Abstract

883,843. Printing-surfaces. AGFA A.G. Sept. 2, 1959 [Sept. 2, 1958], No. 29941/59. Class 100(2) [Also in Group XX] Gelatin used for the production of planographic layers is contacted with an aqueous fluosilicic acid solution of pH5-pH6À5 as by addition thereto prior to casting or incorporation therein by means of an after-treatment bath, which acid at this pH gives a water-absorbing effect even to hardened gelatin; and a printing image may be produced thereon by methods such as typewriting. Examples (see Group XX) are, however, directed to production of the. images by the photographic silver salt diffusion process. Specifications 830,623, 847,436 and 855,610 are referred to.
