Abstract
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.
