Photographic silver halide element with gelatin layer containing silica

摘要

The adhesion of photographic layers to a film base that either has, on one or both sides, a surface consisting of a polyolefin layer that has been treated with a corona discharge, or consists of a polyester film provided with a (first) substrate layer is improved by an adhesive layer that is applied in the form of an oil-in-water emulsion consisting of 50 to 60 wt % of oil-formers and 40 to 50 wt % of a solid consisting of 50 to 80 wt % gelatin and 20 to 50 wt % colloidal SiO2 together with the following layers to the surface of the film base.
