Abstract
The invention provides a pyrrolopyrroledione pigment composition. The pyrrolopyrroledione pigment composition comprises the following components in percentage by weight: 1.0-3% of micro-wax 3620, 0.1-1.0% of an antioxidant 1010, 0.1-1.0% of an ultraviolet light absorber 327, 0.1-1.0% of a hindered amine light stabilizer and the balance of pyrrolopyrroledione. All the components are dispersed, mixed and grinded at a high speed to obtain the pyrrolopyrroledione pigment composition. According to the pyrrolopyrroledione pigment composition, the heat resistance is 300 DEG C, the light-resisting grade is 7 grades and the migration resistance is 4.3 grades. Compared with the prior art, the heat-resisting stability, the light fastness resistance and migration resistance are better; the pyrrolopyrroledione pigment composition can be used for coloring pigments, plastic and paints and can also be used for synthesizing fibers and coloring a basic solution.
Description
Technical field
The present invention relates to a kind of color compositions, particularly, relate to a kind of dione pyrrolo-pyrrole color compositions.
Background technology
In printing-ink, coating etc., by making pigment disperse to bring into play its high tinting strength with micro situation, and make it have the adaptability that is suitable for print or is coated with distinct tone, the gloss etc. of machining object.In addition, by pigment is disperseed with steady state, can significantly cut down the labor capacity while manufacturing printing-ink, coating, and the dispersion of steady state, also has good storage stability conventionally.But in order to realize distincter tone, pigment used in printing-ink, coating, is in most cases minuteness particle, the therefore cohesive force grow between pigment particles, is difficult to possess adaptability as above as a rule.In order to address the above problem, known have the pigment dispersing agent of employing to improve the affinity between pigment and vehicles, thereby realize the method for the stabilization of dispersion, and disclose up to now various pigment dispersing agents.For example, in pigment dyestuff, import the pigment derivative of the functional groups such as acidic groups, basic group, phthalimide methyl.But, because pigment derivative is using pigment dyestuff as precursor skeleton, therefore there is intrinsic strong pigmentation, and in the time of the pigment for different tones, be subject to sometimes significant limitation, for example, to printing-ink, coating, in the system of especially the diketopyrrolo-pyrrole pigment particle of inkjet, ink, the miniaturization of ink for color filter equal altitudes being disperseed, although this pigment dispersing agent is dispersed good, the problem that its dispersion exists distinctiveness (brightness) to reduce.Conventionally, having in the pigment of high tinting strength or distinct tone, in most cases particle is fine, particularly in the pigment of using as colour filter, in order to improve the contrast gradient of film, will apply further miniaturization as a rule compared with pigment in the past.By the method that extensively conduct is applied for preparing the pigmenting method of fine pigment particles, can enumerate lyonium salt mill facture etc. at present.But, in the situation that only pigment being packed into together with common grinding aid used such as inorganic salt or solvent etc., the heating or the solvent adding as dispersing auxiliary etc. that during based on pulverizing, produce, can cause also occurring the phenomenon of the growth of pigment particles simultaneously, or, owing to becoming unstable applying for a long time the state that mechanical force causes pigment particles, therefore can cause the variations such as crystalline transition, even if thereby making time and energy also cannot stably obtain the pigment of abundant miniaturization sometimes.On the other hand, if make the further miniaturization of pigment, can strengthen the cohesive force between pigment particles, ink and coating show high viscosity as a rule.And, manufacturing when this dispersion, exist and be not only difficult to product from dispersion machine, to take out, be transferred to container from dispersion machine, and worse situation is sometimes can initiated gel in storage and become and be difficult to use.In order to address the above problem, known have the pigment dispersing agent of employing to improve the affinity between pigment and vehicles, to realize the stabilization of dispersion, and discloses up to now various pigment dispersing agents.For example, developed the pigment derivative that has imported the functional groups such as acidic groups, basic group, phthalimide methyl in pigment dyestuff; Import the resin type dispersion agent of acidic groups or basic group in the part of acrylate copolymer or vibrin, these can be by separately or and use by mode.
But current dione pyrrolo-pyrrole pigment thermotolerance is 260 ℃, rating for light fastness is 5 grades, resistance to migration is 3 grades, and therefore bad dispersibility has limited its widespread use in coating and plastics, paint, synthon.
Summary of the invention
The object of the invention is to overcome the defect of above-mentioned prior art existence and a kind of dione pyrrolo-pyrrole color compositions is provided, the present invention has improved resistance to migration, light fastness and heat-resistant stability, can be used for the painted of coating and plastics, paint, also can be used for synthon and original liquid coloring.
Object of the present invention is achieved through the following technical solutions, and a kind of dione pyrrolo-pyrrole color compositions comprises the component of following weight percent:
Above-mentioned each component, through high speed dispersion mixed grinding, is obtained final product.
Preferably, described dione pyrrolo-pyrrole color compositions comprises the component of following weight percent:
Above-mentioned each component, through high speed dispersion mixed grinding, is obtained final product.
Preferably, described dione pyrrolo-pyrrole color compositions comprises the component of following weight percent:
Above-mentioned each component, through high speed dispersion mixed grinding, is obtained final product.
Preferably, described hindered amine as light stabilizer is selected from one or more in photostabilizer 622, photostabilizer 770, photostabilizer 944, photostabilizer 783, photostabilizer 791, photostabilizer 3853, photostabilizer 292 and photostabilizer 123.
Preferred, described each component adopts centrifugal high speed dispersion mixed grinding.
Compared with prior art, the present invention has following beneficial effect: thermotolerance of the present invention is 300 ℃, rating for light fastness is 7 grades, 4.3 grades of resistance to migrations, the thermotolerance of the dione pyrrolo-pyrrole pigment in currently available technology is 260 ℃, rating for light fastness is 5 grades, resistance to migration is 3 grades, therefore heat-resistant stability of the present invention, light fastness and resistance to migration are obviously better than prior art, can be used for the painted of coating and plastics, paint, also can be used for synthon and original liquid coloring.
