PURPOSE:To enable the sticking of a polyethylene (PE) layer having an emulsion layer after peeling like a seal or coat-of-arms by specifying the peeling strength of a base and the PE layer. CONSTITUTION:The peeling strength of the base and the PE layer of photographic paper formed by laminating the PE layer directly on the base and further coating a photographic emulsion layer thereof is specified to 5-30g weight. The peeling strength between the base and the PE layer is made into 5-300g weight if the extrusion temp. of the PE to be laminated is set at 280-305 deg.C, more preferably 285-300 deg.C. While a development processing can be executed without generating the peeling between the base and the PE layer during the time of the development process, the PE layer coated with the emulsion layer is easily peelable from the base if a user tries to peel the PE layer in order to use the same as the seal or the coat-of-arms. |
