PURPOSE:To obtain a substratum having superior coatability and adhesion on(to) an emulsion layer causing scarcely putrefaction or decomposition with the lapse of time by providing a substratum cont. a hydrophilic colloid, amphoteric surface active agent, and at least one kind of specified compds.(I) and/or at least one kind of specified compds.(II) on a resin-coated base. CONSTITUTION:A substratum contg. a hydrophilic colloid, an amphoteric surface active agent, and at least one kind of compds. expressed by formula I and/or at least one kind of compds. expressed by formula II, is formed on a resin- coated paper base. In the formulas, R1 is H, alkyl group, or alkoxy group; each R2-R4 is H, halogen, alkyl group, alkoxy group, cyano group, or nitro group; R5 is H, alkyl group, cycloalkyl group, or alkenyl group; each R6 and R7 is H, halogen, alkyl group, cycloalkyl group, aryl group, heterocyclic group, cyano group, or alkylthio group. By this constitution, putrefaction and decomposition of a substratum are prevented, and coatability and adhesion on(to) an emulsion layer are improved. |
