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.
