ABSTRACT IMPROVEMENTS IN OR RELATING TO PHOTOPOLYMERISABLE COMPONENTS OF RADIATION SENSITIVE COMPOSITIONS Colorants, polymeric binder resins, photoinitiators, photosensitizers, colour-change agents, anti-halation agents, stabilizers, and other active hydrogen-containing components of radiation sensitive compositions for lithographic printing plate production and the like are reacted with a polyethylenically unsaturated monoisocyanate compound of the formula Image wherein Y is the residue of a monohydroxyl compound of formula YOH and Y contains at least two ethylenically unsaturated double bonds. In this way the components are bonded to the image on exposure.
