<p>A heat-sensitive plate material for lithographic plate formation which comprises a substrate (1) and a heat-sensitive layer (2) formed thereon. The heat-sensitive layer (2) comprises an organic polymer (4) containing particles (3) forming an oleophilic part. In the heat-sensitive layer (2), a surface part (21) having a thickness of 0.1 µm or more does not contain the particles (3) but contains a metal oxide (5). The surface part (21) comprises a hydrophilic organic polymer (41), which has been cured with the metal oxide (5). That part (22) of the heat-sensitive layer (2) which faces the substrate contains the particles (3). The organic polymer (42) constituting the base part (22) need not be hydrophilic.</p> |
