Abstract
1297947 Incorporating photographic ingredients into hydrophilic colloid compositions AGFAGEVAERT 13 March 1970 [20 March 1969] 14763/69 Heading G2C A method of incorporating a photographic ingredient having a solubility in water at 20C. of not more than 3% by weight into a hydrophilic colloid coating composition for forming a waterpermeable colloid layer of a light-sensitive silver halide element comprises dissolving said ingredient in a mainly water-immiscible organic solvent (having a solubility in water of not more than 25% by weight at 20C.), admixing the solution thus obtained with water in the presence of a dispersing agent but in the absence of a hydrophilic colloid, removing the organic solvent forming thereby a dispersion of the ingredient in water and incorporating the dispersion thus formed in the hydrophilic colloid coating composition. The solubility of the solvent in water is preferably between 2 and 10% by weight at 20C. The solvent preferably has a boiling point of not more than 130C. The solvent may be methylene chloride, ethylformate, n-butyl formate, ethyl acetate, n-propyl acetate, isopropyl acetate, butyl acetate, methyl propionate, ethyl propionate, carbon tetrachloride, sym. tetrachloroethane, 1,1,2- trichloroethane, 1, 2-dichloropropane, chloroform, n-butyl alcohol, diethyl ketone, methyl n-propyl ketone, diisopropyl ether, cyclohexane, methyl cyclohexane, benzene, toluene or nitromethane. An organic solvent completely miscible with water may be used together with the mainly waterimmiscible solvent in order to dissolve the ingredient. The solvent may be removed by evaporation. The hydrophilic coating composition may be a light-sensitive silver halide emulsion. The ingredient may be a colour coupler, maskformer, competing coupler, light-absorbing dye, sensitizing dye or stabilizing agent.
