Appl. No.:

7/871869

Inventors:

Arlene L. Meyer - Pittsford NY

Assignee:

Eastman Kodak Company - Rochester NY

International Classification:

G03C 1815

US Classification:

430510

Abstract:

Photographic glass plates are advantageously prepared by a process in which the functional layers are applied to the glass plate support by lamination. In a first form of this process, a multilayer-composite comprising antihalation, silver halide emulsion and protective overcoat layers is transferred from a flexible polymeric film support to the glass support. In carrying out this first form of the process, a release layer, protective overcoat layer, silver halide emulsion layer and antihalation layer are coated, in order, on a flexible polymeric film and laminated via an adhesive layer to a glass plate having suitable thickness and flatness for use as a photographic support. The release layer is designed to have greater adhesion to the flexible polymeric film than to the protective overcoat layer, whereby the film and release layer can be stripped off prior to the plate being put into use. In a second form of the process, an antihalation layer, silver halide emulsion layer and protective overcoat layer are coated, in order, on a support material comprised of a release sheet, a very thin polymeric film and an adhesive layer interposed between the release sheet and the film, the release sheet is then stripped away and the remainder of the coated support material is laminated via the adhesive layer to the glass plate support. The process of lamination eliminates the difficult task of directly coating photographic layers on glass plates and greatly facilitates the preparation of high quality photographic glass plates in a wide variety of different sizes.

Abstract:

Radiation-sensitive photographic plates are prepared by laminating to a rigid transparent plate support a photographic element comprised of a flexible photographic film support having a radiation-sensitive silver halide emulsion layer on one side thereof and a remoistenable adhesive layer on the opposite side thereof. The adhesive layer is non-tacky in the dry state but is reactivated by moistening so as to strongly bond the photographic element to the rigid transparent plate support.
