Patent ID: 7544462

Claim:
A radiation-sensitive composition comprising: a. an aqueous alkaline developer soluble polymeric binder that comprises a poly(vinyl acetal), and b. a developability-enhancing composition comprising a basic nitrogen-containing organic compound, wherein said developability-enhancing composition comprises one or more basic nitrogen-containing compounds that are represented by the following Structure (II): (R 7 ) s —N—[(CR 8 R 9 ) t —OH] v (II) wherein s is 0, 1, or 2 and v is 1 to 3, provided that the sum of s and v is 3, and t is 1 to 6, and when s is 1, R 7 is hydrogen or an alkyl, alkylamine, cycloalkyl, heterocycloalkyl, aryl, arylamine, or heteroaryl group, and when s is 2, the multiple R 7 groups can be the same or different alkyl, alkylamine, cycloalkyl, heterocycloalkyl, aryl, arylamine, or heteroaryl groups, or the two R 7 groups together with the nitrogen atom, can form a substituted or unsubstituted heterocyclic ring, and R 8 and R 9 are independently hydrogen or an alkyl group, wherein said poly(vinyl acetal) comprises recurring units represented by the following Structure (PVAc): wherein R and R′ are independently hydrogen or an alkyl or halo group, and R 2 is a substituted or unsubstituted phenol, naphthol, or anthracenol group.
