Abstract
Abstract A photographic material capable of receiving and retaining an aqueous ink or other similar materials on the back surface, which is able to serve as a post card, is disclosed. The photographic material comprises a water-proof support comprising a paper sheet coated with a polyolefin resin on both surfaces thereof, and a photographic emulsion layer provided onto one of the surfaces of the support, in which another surface of the support is provided with a gelatin layer containing an inorganic pigment and one or more of specific gelatin hardening agents.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
210 words
In a process for placing letters, pictures or stamps fixedly on a back surface of a photographic material, the improvement which comprises said photographic material comprising a water-proof support comprising a paper sheet coated with a polyolefin resin on both surfaces thereof, and a photographic emulsion layer provided onto one of the surfaces of the support, in which another surface of the support is provided with a gelatin layer containing an inorganic pigment and one or more gelatin hardening agents selected from the group consisting of those of the active vinyl type, active halogen type, epoxy type, ethyleneimino type, methanesulfonic acid ester type, carbodiimide type, isoxazole type, active ester type, isocyanate type, dehydration-condensation peptide type and inorganic type, said gelatin layer being present on the surface of the support in an amount of from 0.5 to 20 g/m 2 , and containing gelatin and an inorganic pigment in the amount from 85-50 parts by weight and 15-50 parts by weight, respectively, and further containing a gelatin hardening agent in an amount from 0.2 to 3 parts by weight of the gelatin layer, said inorganic pigment having an absorbing capacity of not less than 100 cc/100 g, and placing the letters, pictures or stamps on the surface of said gelatin layer.
Claim 2
Dependent Claim
