The reaction method is not particularly limited. For example, the reactive monomer of the formula (XII) can be obtained simply by mixing.

  As a method for producing the compound of the above formula (XII), when a (meth) acryloyl group-containing aromatic isocyanate compound and a compound containing a hydroxyl group are reacted in a solvent, a urethanization catalyst may be used. Generally done. By using the urethanization catalyst, the reaction can be remarkably accelerated.

  Examples of the urethanization catalyst include dibutyltin dilaurate, copper naphthenate, cobalt naphthenate, and zinc naphthenate. However, since these catalysts all contain heavy metals, it is desirable to avoid using them as much as possible in consideration of environmental considerations.

The reactivity of aromatic isocyanate in the urethanization reaction is greatly influenced by the electron withdrawing property or substituent constant of the substituent on the aromatic ring.
The substituent constant is a parameter that is defined based on Hammett's formula and quantifies the reactivity of a substituent having an active hydrogen on the aromatic ring. When the substituent is a hydrogen atom, the substituent constant is 0. Is defined as Generally, the substituent constant of the electron-donating group is negative and the substituent constant of the electron-withdrawing group is positive. The higher the absolute value, the greater the effect.

  In the aromatic isocyanate represented by the general formula (I) of the present invention, the higher the electron withdrawing property of the substituent, the more desirable in terms of increasing the reactivity of the isocyanate group, and the substituent constant is a positive value. It is desirable in that the reaction can be promoted.

  For example, when unsubstituted phenyl isocyanate or p-methylphenyl isocyanate is used, the reactivity of the isocyanate group tends to be greatly reduced as compared with the aromatic isocyanate represented by the general formula (I). It is in.

  The substituent constant of unsubstituted phenyl isocyanate is 0 as described above, and the substituent constant of p-methylphenyl isocyanate is −0.17, both of which are not positive values, and both are electron-withdrawing groups. not. This supports the result that the reactivity of the isocyanate groups of both compounds is low compared to the isocyanate monomer of general formula (I).

  On the other hand, the compound represented by the general formula (I) has sufficient reactivity with respect to a hydroxyl group, and can complete the reaction for producing the reactive monomer without using a catalyst. is there. The reaction temperature is preferably 0 ° C to 60 ° C, more preferably 25 ° C to 40 ° C. If the reaction temperature is less than 0 ° C., the reaction may not be completed and the raw materials may remain. If the reaction temperature exceeds 60 ° C., side reactions may occur or coloring may occur.

In addition, by using the above method, the reaction composition can be simplified and the burden on the environment can be reduced by eliminating heavy metals, which is very useful industrially.
It is known that the above reaction proceeds even with a group other than a hydroxyl group, an amino group, and a mercapto group. For example, since an isocyanate group also reacts with a carboxyl group or the like, a reactive ethylenically unsaturated group can be introduced by addition by reaction.

Therefore, a hydroxyl group, an amino group, or a combination of such a (meth) acryloyl group-containing aromatic isocyanate compound of formula (I) and an isocyanate compound containing one reactive ethylenically unsaturated group You may make it react with the compound containing a mercapto group.

When the usage-amount of a polymerization initiator will be less than 0.1 weight part, the polymerization rate of a reactive monomer may become slow. Moreover, it may become easy to receive the polymerization inhibition by oxygen etc. On the other hand, when the usage-amount of a polymerization initiator exceeds 20 weight part, a polymerization reaction will be suppressed conversely and the intensity | strength of a cured film obtained, adhesive strength, and heat resistance may fall. Furthermore, it causes coloring.

Thereafter, it is cured by thermosetting at a temperature of 100 to 180 ° C. for about 10 to 40 minutes.

  This curable composition is particularly excellent in flexibility when made into a cured product, and the cured product has good flexibility, so it is particularly suitable for use as an insulating protective film on an FPC board. Therefore, the FPC board can be made excellent in handleability. Further, for example, it may be used as an insulating resin layer between layers of a multilayer printed wiring board.

The cover film is peeled off when the dry film resist is used, but by providing the cover film on the photosensitive layer until the time of use, the photosensitive layer can be protected and a dry film resist excellent in pot life can be obtained.

  In order to form an insulating protective film on a printed wiring board using a dry film resist, first, the photosensitive layer of the dry film resist and the substrate are bonded. Here, when using a dry film resist provided with a cover film, the cover film is peeled off to expose the photosensitive layer, and then contacted with the substrate.

  Next, the photosensitive layer and the substrate are thermocompression bonded at about 40 to 120 ° C. using a pressure roller or the like, and the photosensitive layer is laminated on the substrate. Thereafter, the photosensitive layer is exposed through a negative mask having a desired exposure pattern, the support is peeled off from the photosensitive layer, the unexposed portion is removed with a developer and developed, and the photosensitive layer is thermally cured. A printed wiring board having an insulating protective film provided on the surface of the substrate is manufactured. Moreover, you may form an insulating resin layer between the layers of a multilayer printed wiring board using such a dry film resist.
