ABSTRACT A coating composition for coated front copy papers comprises pre-treated caxboxylated soybean protein, pigment, binder, phenolic resin, and defoamer. In a preferred embodiment, the carboxylated soybean protein is pre-treated by the steps of: (a) adding carboxylated soybean protein to water in a mixer, (b) continuing mixing to achieve an even dispersion, (c) heating the dispersion to a temperature of 58 - 65°C while continuing mixing, (d) adding sufficient ammonia solution to neutralize the carboxylic acid groups in the protein, and (e) maintaining the temperature in the range 58 - 65°C until the reaction is complete as indicated by pH, or by complete dissolution of the protein, and (f) adding defoamer and mixing by gentle agitation. A method for coating paper is also claimed.
