Abstract

826,005. Photographic light-sensitive materials. OZALID CO. Ltd. Feb. 3, 1956 [Feb. 4, 1955], No, 3452/55. Class 98(2) The support of a light-sensitive photocopying material such as diazo-type material is treated with an aqueous suspension of finely divided aluminium silicate of average particle size from 0.01 to 1 microns. Finely divided silica and/or unburst starch grain may be mixed with the aluminium silicate. Alternatively the silicate may be mixed with casein. A binder such as polyvinyl acetate, solubilized starch or starch ether may be added to the suspension and the sensitizing solution also may be included in the suspension. Reference has been directed by the Comptroller to Specification 762,117.
