Abstract

1,263,722. Coated sheet material. KODAK Ltd. 22 May, 1969 [24 May, 1968], No. 24865/ 68. Heading B2E. [Also in Division G2] A process of producing a lubricant-containing layer for a photographic material from a coating composition comprising an aqueous hydrophilic colloid solution comprises adding to the coating composition (1) a higher aliphatic carboxylic acid (i.e. one whose calcium salt is substantially insoluble in 10% aqueous gelatin solution and which imparts lubricant properties to a gelatin layer containing its calcium salt) and/or a water soluble salt thereof and (2) alkaline earth metal ions so that the total alkaline earth metal ion concentration of the solution is in stoichiometric excess of the concentration of the carboxylic acid and/or its water-soluble salt and thereafter coating the composition on a substrate. The preferred alkaline earth metal in calcium. The higher aliphatic carboxylic acid may have 8-18 carbon atoms and is preferably lauric or stearic acid, and the water soluble salt thereof may be the sodium salt. The alkaline earth metal ions (2) may be added to the hydrophilic colloid solution before the addition of the acid and/or salt (1). The preferred hydrophilic colloid is gelatin. The pH of the coating solution is preferably 5.8 to 6.5.
