    摘要： A planographig printing plate precursor which can be written by heat mode exposure of low energy, has excellent strength in image portions and blemishing resistance, can be developed with water, or can be installed in a printing machine as it is for conducting printing without requiring specific treatment such as wet developing treatment, rubbing and the like after writing of an image, and a method for producing the same, are provided. The planographic printing plate precursor of the present invention is obtained by laminating on a substrate having a hydrophilic surface a layer composed of a hydrophobic polymer which is made hydrophilic by heating and either a layer composed of a hydrophilic polymer compound having in the side chain at least one of alkylene oxide groups or functional groups selected from --COOR, --COOM, --SOR, --SO.sub.2 R, --SO.sub.3 R, --SOM, --SO.sub.2 M, --SO.sub.3 M, --OH, --NR.sup.22 R.sup.23 (wherein, R represent a hydrogen atom, alkyl group or aryl group, M represents a metal atom, R.sup.22 and R.sup.23 each independently represent a hydrogen atom, alkyl group or aryl group) or a layer of which exposed portions can be removed by heat mode exposure.
