<p>PURPOSE:To obtain the titled body having improved application property and adhesive strength against the photographic emulsion of the under coat by maintaining a hydrogen ion concentration of a surface of the under coat to a specific range, and by incorporating an aziridine compd. to a hardener. CONSTITUTION:The hydrogen ion concentration of the surface of the under coat is maintained to a range of 5.2-6.2. And, the hardener contains at least one kind of the aziridine compd. The hardener of the under coat contains at least one kind of the aziridine compd. and preferably contains the aziridine compd. having >=2 ethylene imino groups per one molecule. The used amount of the aziridine compd. to a gelatin is preferably 0.5-3X10<-4>mol per 1g of the gelation. If pH of the surface of the under coat is deviated from a range of 5.2-6.2, the sticking property against the photographic emulsion of the under coat is remarkably reduced.</p> |
