摘要： The objective is to provide a direct drawing-type waterless lithographic printing original plate which is highly sensitive and is not susceptible to formation of blisters, namely a direct drawing-type waterless lithographic printing original plate which has a wide latitude. Provided is a direct drawing-type waterless lithographic printing original plate which has at least a heat-sensitive layer and a silicone rubber layer on a substrate in this order. The direct drawing-type waterless lithographic printing original plate is characterized in that the heat-sensitive layer contains non-photosensitive particles and the average particle diameter of the non-photosensitive particles is not less than ½ of the average film thickness of a portion of the heat-sensitive layer where the non-photosensitive particles are not present.

摘要： A directly imageable waterless lithographic printing plate precursor includes at least a heat sensitive layer and a silicone rubber layer formed on a substrate in this order, wherein the heat sensitive layer contains at least a novolac resin, a polyurethane and a light-to-heat conversion material, and also has a phase separation structure including at least a phase containing a novolac resin and a phase containing a polyurethane. The directly imageable waterless lithographic printing plate precursor has high sensitivity and is less likely to cause blister, that is, having wide latitude.

摘要： A directly imageable waterless planographic printing plate precursor includes at least a heat sensitive layer and a silicone rubber layer formed on a substrate in this order and has a high sensitivity not only immediately after the precursor production but also after the passage of time. In the directly imageable waterless planographic printing plate precursor, the heat sensitive layer contains liquid bubbles filled with a liquid with a boiling point in the range of 210 to 270° C. A production method comprises applying a solution of a heat sensitive layer composition containing a solvent with a solubility parameter of 17.0 (MPa)1/2 or less and a boiling point in the range of 210 to 270° C. and a solvent with a solubility parameter of more than 17.0 (MPa)1/2 over a substrate or a substrate coated with a resin layer, drying the solution of a heat sensitive layer composition to form a heat sensitive layer, and applying a silicone rubber layer composition over the heat sensitive layer to form a silicone rubber layer.
