ABSTRACT:
A radiation sensitive composition containing an adduct of a diazonium resin having pendant diazonium groups, with a sulfonated acrylic copolymer having pendant sulfonate groups. The sulfonated acrylic copolymer contains an acrylic moiety and a sulfonated styryl or acrylic moiety. The copolymer may optionally contain styryl moieties. The composition is useful as a radiation sensitive layer in imaging elements for graphic arts applications and is particularly useful in preparing durable, long-wear, printing plates.
