PRINTING PLATE MATERIAL AND PROCESS FOR PRODUCING PRINTING PLATE

摘要

This invention provides a printing plate material comprising a base material and a thermal image forming layer and a constituent layer provided on the base material. The printing plate material is characterized in that the thermal image forming layer contains a silicate and a carbonate, the constituent layer is provided between the base material and the thermal image forming layer, and at least one of the constituent layer and the thermal image forming layer contains a photothermal conversion agent. The printing plate material has excellent print starting properties, printing durability, and scratch mark fouling preventive properties. There is also provided a process for producing a printing plate.
