Abstract
Photographic glass plates can be prepared by directly coating the appropriate layer formations onto a glass support. One element comprises a thin subbing layer (less than 2 .mu.m), an antihalation layer, a silver halide emulsion layer, and a protective overcoat layer that can also include a matting agent or lubricant. Another embodiment has the antihalation layer coated directly onto the support.
