Abstract
Abstract There is disclosed a reflective photographic material having photosensitive emulsion layers applied on at least one side of a support film of thermoplastic resin essentially comprised of polyester resin that contains white pigment containing 90% by weight or more of surface-treated titanium oxide having an average particle size of 0.1 µm to 0.5 µm and including substantially no particles whose size is 50 µm or more. The disclosed photographic material shows excellent whiteness, opacity, gloss and resolving power. A permeation of a photographic processing liquid through the cut edge of the support of said photographic material does not take place.

A photographic material characterized by that photosensitive emulsion layers are applied on at least one side of a support film of thermoplastic resin essentially comprised of polyester resin that contains white pigment containing 90% by weight or more of surface-treated titanium oxide having an average particle size of 0.1µm to 0.5µm and having substantially no particles whose size is 50µm or more.
Claim 2
Dependent Claim
62 words
A photographic material characterized by that photosensitive emulsion layers are applied on at least one side of a support film of thermoplastic resin essentially comprised of polyester resin that contains white pigment containing 90% by weight or more of surface-treated titanium oxide having an average particle size of 0.1µm to 0.5µm and having substantially no particles whose size is 50µm or more.
Claim 3
Dependent Claim
