ABSTRACT:
An alkali-soluble binder resin made by a condensation reaction of hydroxy styrene moiety having formulae (I) or (II): ##STR1## wherein x is an integer from 2 to 300; with a monomethylolated phenolic compound having a formula (III): ##STR2## wherein R.sub.1 and R.sub.2 are individually selected from the group consisting of lower alkyl group having 1-4 carbon atoms, lower alkoxy group having 1-4 carbon atoms, amino group, and carboxylic acid group; wherein R.sub.3 and R.sub.4 are individually selected from the group consisting of hydrogen, lower alkyl group having 1-4 carbon atoms, lower alkoxy groups having 1-4 carbon atoms, an amino group, and a carboxylic group; and wherein the mole ratio of the hydroxy styrene moiety to the monomethylolated phenolic compound is from about 1:10 to about 10:1.
