    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.

    摘要： The present invention provides an abrasive pad for abrading a surface to be abraded in the presence of an abrasive solution, which includes a hydrophobic polymer as a base material, and in which a graft-polymer chain having a hydrophilic group is introduced into the surface of the hydrophobic polymer. The hydrophilic group possessed by the graft-polymer chain is preferably a nonionic hydrophilic group selected from the group consisting of hydrophilic groups having an N-monoalkyl substituted structure and hydrophilic groups having an N-dialkyl substituted amide group. An amount of the hydrophilic graft-polymer to be introduced into the base material is preferably 10.0% to 150.0% in terms of graft ratio.

    摘要： A negative planographic printing plate precursor includes a negative recording layer on a support. The support has a hydrophilic surface with hydrophilic graft polymer chains present therein. The negative recording layer contains a radical generator, a radical-polymerizing compound, and a photo-thermal converting agent. Preferably, the hydrophilic graft polymer chains are directly bonded to the support surface or to an intermediate layer formed on the support surface, or are introduced into a crosslinked polymer film structure.
