Abstract

PURPOSE:To enable a photographic coating fluid to be uniformly coated at a high speed to form a thin film by adding a polysaccharide having glucose units as the principal chain and mannose and glucuronic acid units as the linear side chains to the fluid. CONSTITUTION:To a photographic coating fluid containing acid-treated gelatin, etc. is added about 0.01-30wt% of a polysaccharide having units of glucose of formula I as the principal chain and units of mannose of formula II and glucuronic acid of formula III as the side chains. This polysaccharide preferably has two glucose units, two mannose units and one glucuronic acid unit in one constitutive unit. By this composition the fluid can uniformly be coated onto a support to form a thin film without causing looseness and running of the film, and the fluid has increased stability and becomes easy to handle.
