PURPOSE:To provide the titled original form, by which a printing plate whose fixing property of a toner picture is excellent and whose printing resisting property is excellent as well can be formed, by providing a hydrophilic picture accepting layer, whose main components are a pigment and a binder comprising ionomer resin or the like, on a supporting body. CONSTITUTION:A binder comprises a mixture of a hydrophilic resin and 5- 50wt%, desirably 10-35wt%, of ionomer resin, whose neutralization degree is adjusted to 50-90%. In this binder, 2-7pts.wt. (with respect to 1pt.wt. of the binder) of a pigment (e.g., zinc oxide or the like) is added, and dissolved or dispersed in water. The material is applied on a supporting body so that the amount of the attachment of a solid component becomes 5-15g/m<2>. The material is dried and a hydrophilic picture accepting layer is provided. Thus a desired original form is obtained. |
