Abstract (en)
[origin: EP0695968A2] An aqueous photographic coating composition comprises an aqueous solution comprising gelatin and an anionically charged, hydrophobic group-containing compound that is (a) soluble in water or a mixture of water and a water-miscible organic solvent, and (b) which confers an undesirably high viscosity to aqueous gelatin solutions, wherein the composition further comprises a cyclodextrin in an amount sufficient to reduce the viscosity of the solution. <MATH>
