The present invention relates to a heat mode-compatible planographic printing plate comprising a photosensitive layer which is capable of recording with an infrared laser and formed by applying a photosensitive layer coating solution onto a hydrophilic support and then drying the photosensitive layer coating solution, the photosensitive layer coating solution being obtained by dissolving or dispersing I) an IR absorber, II) a polymerization initiator, and III) a compound having a polymerizable unsaturated group in a solvent, wherein the residual solvent in the photosensitive layer is 5% by weight or less relative to the weight of the photosensitive layer.
A heat mode-compatible planographic printing plate comprising a photosensitive layer which is capable of recording with an infrared laser and formed by applying a photosensitive layer coating solution onto a hydrophilic support and then drying the photosensitive layer coating solution, said photosensitive layer coating solution being obtained by dissolving or dispersing I) an IR absorber, II) a polymerization initiator, and III) a compound having a polymerizable unsaturated group in a solvent, wherein the residual solvent in the photosensitive layer is 5% by weight or less relative to the weight of the photosensitive layer.
A heat mode-compatible positive planographic printing plate comprising a photosensitive layer whose solubility in an aqueous alkali solution increases upon heat-mode exposure and which is formed by applying a photosensitive layer coating solution onto a support and then drying the photosensitive layer coating solution, said photosensitive layer coating solution being obtained by dissolving or dispersing a photosensitive composition in a solvent, said photosensitive composition contains a polymer insoluble in water but soluble in an aqueous alkali solution, wherein the residual solvent in the photosensitive layer is 5% by weight or less relative to the weight of the photosensitive layer.
