Abstract
A photopolymerisable material comprises a carrier having a layer composed of (1) ethylenically unsatd. monomers which are soluble in water (-alcohol mixts.) and which contain >=1 terminal double bond and >=1 polar gp. having a lone electron pair; (2) a photoinitiator having a ring system of formula: (where Z is n or C-R; R is H or a substituent; and the cpd. is opt. quaternised); (3), as a matrix for the monomer (1), the swellable -reaction prod. of (a) a macromolecular binder which is soluble in water (-alcohol mixts.) and which has >=1 polar gp. contg. a lone electron pair, and (b) a hardener which is different from monomers (1); and opt. (4) a chemically inert macromolecular cpd. which does not reac with binder (a) or hardener (b). The material is used for recording images. The hardened binder (matrix) in which the photopolymer is embedded imparts to the image a good mechanical strength and a good adhesion to the carrier, so that then polymeric images can be used e.g. as printing plates.
