<p>A photothermally sensitive composition which is primarily energy sensitive in the near infrared and ultraviolet region of the electromagnetic spectrum is composed of a novolak polymer, a melamine derivative crosslinking compound, an acid-generating compound, a polymeric dissolution inhibitor selected from cellulose acetate butyrate, cellulose acetate propionate and mixtures thereof and an infrared absorbing dye. When applied to the proper support and processed, the composition is useful as an offset lithographic printing plate, color proofing film or image resist.</p> |
