<p>Liquid petroleum sulphonates are useful, on their own or 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. Crystallisation of the addenda is inhibited and, for some addenda, other advantages are obtained.</p> |
