THERMOSENSITIVE IMAGING COMPOSITION AND LITHOGRAPHIC PLATE COMPRISING THE SAME

摘要

A positive-working thermo-sensitive lithographic printing plate consists of a hydrophilic substrate and a thermo-sensitive image recording composition. Said thermo-sensitive image recording composition comprises (A) a resin having a self-dissolution inhibiting ability; and (B) an infrared absorber. The resin is an alkali-soluble resin that contains phenolic hydroxyl group, and carbamate or thiocarbamate group that has strong electron-absorbing ability.
