PURPOSE:To obtain the titled body having the stable and strong sticking property to an emulsion layer by coating an aqueous coating solution of an undercoating layer on a prescribed surface of the titled body which is provided with a photographic constituting layer, when the titled body is wound up, after a resin having the film forming property is coated on the both surfaces of a running paper by melt-extruding, followed by drying it, thereby providing with an undercoating layer on the titled body. CONSTITUTION:The aqueous coating solution of the undercoating layer is coated on the prescribed surface of the titled body which is provided with the photographic constituting layer, when the titled body is wound up, after the resin having the film forming property is coated on the both surfaces of the running paper by melt-extruding, followed by drying it, thereby providing with the undercoating layer on the titled body. The coating amount of the undercoating layer is not specified, and is preferably coated 1-10gm<2> of the aqueous coating solution contg. 0.1-5.0wt.% gelatin. If necessary, the undercoating solution may optionally contain various kinds of the surface active agents such as an anionic, a cationic, a nonionic or a fluorine contg. surface active agent, etc., and a pH controller or a pH buffer solution and a gelatin curing agent, a toning agent, a whitening agent and a fuller, etc. Thus, the titled body having the stable and strong sticking property to the emulsion layer is obtd. |
