A waterless planographic printing plate precursor is capable of plate inspection without a post-dyeing step, capable of being handled in a light room and excellent in coloring matter fixing in silicone rubber layer. The waterless planographic printing plate precursor has at least a photosensitive layer or heat sensitive layer and a silicone rubber layer on a substrate, which is a waterless planographic printing plate precursor characterized in that a color pigment is contained in the above-mentioned silicone rubber layer, and it is possible to obtain a more excellent effect by further incorporating, in the above-mentioned silicone rubber layer, a pigment dispersant containing an organic complex compound comprising of a metal and an organic compound. Furthermore, when aluminum and/or titanium is contained as the above-mentioned metal, a more excellent effect can be obtained.
A waterless planographic printing plate precursor having, on a substrate, at least a photosensitive layer or heat sensitive layer and a silicone rubber layer, which is a waterless planographic printing plate precursor characterized in that a color pigment and a pigment dispersant are contained in said silicone rubber layer, wherein said pigment dispersant contains an amine-based pigment dispersant as described in formulae (3):
