Light-sensitive compositions and articles utilizing a compound or polymer containing an aromatic diazonium salt group and a light-absorbing residue of a sensitizing dye for trichloromethyl-s-triazine or azinium salt photopolymerization initiators

摘要

A light-sensitive composition comprising either an alkali- soluble resin or radical-polymerizable, unsaturated compound, and a diazonium compound represented by general formula (I) or (II):P P(S). sub.1 --(L.sup.1).sub.m --(D).sub.n (I)PP-- (L.sup.2 (S)). sub.o --(L.sup.3 (D)).sub.P -- (II)PP wherein D is a diazonium salt group, S is a light absorbing group, L.sup. 1, L.sup.2 and L.sup.3 are connecting groups connecting S and D, provided that S and D are not conjugated by L.sup.1, L.sup.2 and L.sup.3 ; l, m, n, o and p are integers.
