Abstract
A heat mode type lithographic printing plate precursor which can be directly mounted on a printing press without development processing after scanning exposure for a short time to conduct plate-making, has excellent press life and also gives few print stains onto a printed face, which comprises a substrate having provided thereon an image recording layer containing fine light-heat convertible particles which are coated with a hydrophilic material, the layer being made hydrophobic by the action of heat.
Claims5
A lithographic printing plate precursor comprising a substrate having provided thereon an image recording layer containing fine light-heat convertible particles which are coated with a hydrophilic material, the layer being made hydrophobic by the action of heat.
A lithographic printing plate precursor comprising a hydrophobic substrate or a substrate provided with a hydrophobic layer, the substrate having provided thereon an image recording layer comprising a hydrophilic medium comprising fine light-heat convertible particles which are coated with a hydrophilic material, and image recording is conducted by removing the hydrophilic medium by laser beam irradiation.
