A heat-sensitive lithographic printing plate precursornwhich comprises a substrate having thereon an anodic oxidationnlayer, with the printing plate precursor comprising anhydrophilic layer containing at least one kind of fine particlesnselected from the group consisting of heat-fusible hydrophobicnthermoplastic fine particles, finely divided polymers havingnthermally reactive functional groups and microcapsules in whichncompounds having heat-reactive functional groups arenencapsulated, and with the anodic oxidation layer having ansurface over which micropores having an average pore size ofn6 to 40 nm are uniformly distributed. |
