-1- DICHROMATED HYDROPHILIC COLLOID-LATEX COPOLYMER COMPOSITIONS ABSTRACT OF THE DISCLOSURE The properties of a dichromated hydrophilic col- loid photosensitive composition are improved by the incor- poration of certain copolymer latices. More particularly, the copolymer particles in the latex conform to the struc- ture: Image wherein: A is a polymerized monomer or monomers having the structure: Image and B is a polymerized monomer or monomers having the structure: Image wherein: each R1 is independently hydrogen or methyl; R2 is phenyl, substituted phenyl or a straight- or branched-chain alkoxycarbonyl group of about 2-8 carbon atoms; R3 is -NR4R5 or -OR6 wherein R4 and R5 are inden- dently selected from hydrogen, alkyl of about 1-8 carbon atoms including substituted alkyl, and alkyl containing -11- hetero atoms in the alkyl chain, and R6 is hydroxyalkyl of about 1-8 carbon atoms; and a represents a weight percent of about 75-95.
