A PHOTOSENSITIVE COMPOSITION, AN ARTICLE COMPRISING THE COMPOSITION AND THE USE OF THE COMPOSITION AS A PHOTORESIST

摘要

The properties of a dichromated hydrophilic colloid photosensitive composition are improved by the incorporation of certain copolymer latices. More particularly, the copolymer particles in the latex conform to the structure: -A)(B - phi -a wherein A is a polymerized monomer or monomers having the structure: and B is a polymerized monomer or monomers having the structure: 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 independently selected from hydrogen, alkyl of about 1-8 carbon atoms including substituted alkyl, and alkyl containing 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.
