Abstract:
1. A printing plate material comprising a support and provided thereon, a hydrophilic layer and a thermosensitive image formation layer containing a blocked isocyanate compound, which is a reaction product of an isocyanate compound, a polyol, and an isocyanate group-blocking material, wherein the isocyanate compound is selected from the group consisting of an aromatic polyisocyanate, an aliphatic polyisocyanate, an alicyclic polyisocyanate and an aromatic aliphatic polyisocyanate, and the polyol is selected from the group consisting of propylene glycol, triethylene glycol, glycerin, trimethylol methane, trimethylol propane, pentaerythritol, neopentyl glycol, 1,6-hexylene glycol, hexamethylene glycol, xylylene glycol, sorbitol, sucrose, polyether polyol, polycarbonate polyol, polycaprolactone polyol, polyester polyol, and polybutadiene polyol, and wherein the thermosensitive image formation layer is formed by coating on the support an aqueous thermosensitive image formation layer coating liquid containing the blocked isocyanate compound.
