A planographic printing plate precursor comprises a support and two or more positive recording layers which are formed on the support, contain a resin and an infrared absorbing agent and exhibit an increase in solubility in an aqueous alkali solution by exposure to infrared laser light, wherein the positive recording layer closest to the support among these two or more positive recording layers contains at least two types of resins among which at least one type forms a dispersion phase. It is pr...

A lithographic printing plate precursor capable of forming an image upon irradiation with an infrared laser comprising a support, a first layer containing as the main component an alkali-soluble resin and a second layer containing as the main component an alkali-soluble resin that is different from the alkali-soluble resin contained as the main component in the first layer in this order, and at least one of the first layer and the second layer contains a mixture comprising at least two kinds of ...

A planographic printing plate precursor includes a support having disposed thereon a recording layer containing a water-insoluble and alkali-soluble resin, a development inhibitor and an infrared absorber and exhibiting enhanced solubility in an aqueous alkali solution through light exposure. The recording layer may have either a mono-layer construction or a multi-layer construction containing a lower layer and an upper layer. In the case of the multi-layer construction, a layer containing the w...
