Abstract
Abstract Disclosed are a photopolymerizable mixture and photopolymerizable copy materials made therefrom. The mixture contains a polymerizable compound having terminal acrylic or methacrylic acid ester groups and being selected from a compound of the formula I ##STR1## wherein R 1 is a naphthylene group, a biphenyldiyl group or a dinaphthyl-methanediyl group or a group formed by two phenylene groups which are linked by a bridge comprised of an oxygen atom, a sulphur atom, a sulfone group or an alkylene group which is substituted by at least one carboxylic acid group, carboxylic acid alkyl ester groups, halogen atom or phenyl group, or by such a substituted alkylene group which is connected to the group R 1 of another molecule via said substituent; R 2 is a hydrogen atom or a methyl group; and m is 0 or 1, m being 1 if R 1 is a naphthylene group or a biphenyldiyl group.

Claim 1
Independent Claim
171 words
A mixture which is polymerizable by radiation, comprising: (a) a polymerizable compound having terminal acrylic or methacrylic acid ester groups and being selected from a compound of the formula I ##STR35## wherein R 1 is a naphthylene group, a biphenyldiyl group or a dinaphthylmethanediyl group or a group formed by two phenylene groups which are linked by a bridge comprised of an oxygen atom, a sulphur atom, a sulfone group or an alkylene group which is substituted by at least one carboxylic acid group, carboxylic acid alkyl ester groups, halogen atom or phenyl group, or by such a substituted alkylene group which is connected to the group R 1 of another molecule via said substituent; R 2 is a hydrogen atom or a methyl group; and m is 0 or 1, m being 1 if R 1 is a naphthylene group or a biphenyldiyl group; (b) a polymeric binder which is soluble or at least swellable in an aqueous-alkaline solution; and (c) a polymerization initiator which can be activated by radiation.
