PURPOSE:To lessen the generation of a fog in an image, and the penetration of a developer from the cut end of a photographic printing paper by incorporating a specified compd. in the base paper layer of a resin coated paper and by specifying pH of the base paper layer. CONSTITUTION:Dialkyl ketene and/or dialkyl ketone A, an epoxidized higher fatty acid amide B contg. a higher fatty acid and a polyalkylene polyamine as a main component, and a polyamide polyamine epichlorohydrin resin C are incorporated in the base paper layer of the resin coated paper which is the supporting body of the sensitive material. And, the pH of the base paper layer is 5.5-8.0. The sensitive material is subjected to a development processing with the color developer which does not substantially contain benzylalcohol, at a temp. of >=30 deg.C for less than 90sec. And, the component A/B is incorporated in the sensitive material in a ratio of (9/1)-(3/7). The component A of 0.1-1.0wt.%, and the component C of 0.1-1.5wt.% based on a pulp are incorporated in the base paper, respectively. |
