Abstract

Disclosed is a lithographic printing plate material having a heat-sensitive image-forming layer on a supporting body. This lithographic printing plate material is characterized in that the heat-sensitive image-forming layer contains particles (A) having a recessed portion in the surface. This lithographic printing plate material is excellent in on-press developability and exposure visible image properties, while being suppressed in changes in visible images after exposure.
