Abstract:
Radiation-sensitive material comprising:A) a flexible laminate of two or more sheet-form materials, of which at least one is transparent to radiation,B) a coloured photopolymerizable layer which comprisesB1) a polymeric binder,B2) a free-radical-polymerizable compound,B3) a compound or combination of compounds which is capable of initiating polymerization of B2 on exposure to actinic light, andB4) a dye or coloured pigment, andC) a heat-activatable adhesive layer on the photopolymerizable layer, wherein the adhesion between the two sheet-form materials is less than the adhesion between the photopolymerizable layer and the adjacent sheet-form material; andwherein the sheet-form material adjacent to the photopolymerizable layer is transparent and has a thickness of from 10 to 35 .mu.m.
