Control of pressure-fog with gelatin-grafted and case-hardened
gelatin-grafted soft polymer latex particles
摘要:
This invention describes a substantially less pressure sensitive photographic film comprising a support, at least one light sensitive silver halide element, and an overlaying element comprising gelatin-grafted or case-hardened gelatin-grafted soft polymer particle composite element. The incorporation of such an overlaying composite particle cushioning layer does not compromise either the physical properties or physical integrity of the film unit. This invention is particularly suitable for highly pressure sensitive tabular grain emulsions.
