ABSTRACT:
Liquid petroleum sulfonates are useful alone or in combination with less lipophilic anionic surfactants in the preparation of dispersions of water-insoluble photographic addenda, such as couplers and ultraviolet absorbers, in hydrophilic colloid compositions. Such dispersions are useful in photographic elements. Crystallization of the addenda is inhibited and, for some addenda, other advantages are obtained.
