Abstract
It is generally undesirable to have surfaces on photographic elements which are highly reflective and therefore reduce the attractiveness of the image. One of the traditional means of correcting this reflectance is to coat the developed film or print with an anti-reflective coating or to place a glass cover over the imaged photographic element where the glass itself has an anti-reflective surface. According to the present invention, an anti-reflective surface may be provided within the photographic element itself by including within a top coat gelatin layer a combination of a first water-soluble soft matting agent incompatible with gelatin and a second water-insoluble soft matting agent.
