PURPOSE:To easily remove an antihalation layer at the time of a development by forming silver halide emulsion layer on one side of a support and on the other side the antihalation layer contg. a specified cellulose acetate phthalate. CONSTITUTION:On one side of the support, the silver halide emulsion layer is formed and on its other side, the antihalation layer is formed. This layer contains hydroxyalkyl alkyl cellulose acetate phthalate, such as hydroxypropyl methyl cellulose acetate phthalate, thus permitting the obtained photographic sensitive material to be prevented from the migration of the antihalation material even when this layer contacts with the silver halide emulsion layers at high temp., and this layer to be easily removed at the time of the development. |
