Abstract
Coating-compositions for coating papers are prepared by adding to a filler a binding agent comprising a neutral solution containing a relatively small amount of one or more water-soluble cellulose ethers. Further binding agents, e.g. casein or starch, may also be incorporated. In examples: (1) a solution in water of 50 parts of methyl cellulose is stirred with 2,000 parts of china clay; (2) 50 parts of methyl, cellulose are dissolved in 5 per cent starch solution and mixed with 5,000 parts of calcium carbonate; (3) 1,000 parts of white pigment are stirred into an aqueous solution of 50 parts of the sodium salt of cellulose glycollic acid; and (4) 20 parts of cellulose glycollic acid dissolved in weak soda solution and 100 parts of casein are mixed with 2,000 parts of blanc fixe. Reference has been directed by the Comptroller to Specifications 181,393, [Class 2 (ii)], and 359,618.
