摘要:
Photographic elements comprising loaded latex compositions are prepared by (a) combining under conditions of low or moderate shear, in the presence of surfactant, and in the substantial absence of water-miscible or volatile organic solvents, a liquid organic composition comprising at least one photographically useful compound with an aqueous polymer latex, (b) holding the combination resulting from (a) in a liquid state for sufficient time for substantial loading of the organic coposition into the polymer latex to occur, and (c) coating the loaded latex resulting from (b) on a support.
