摘要： A hydrophobically capped oligomeric acrylamide or pyrrolidone is employed as a dispersant for hydrophobic materials in an aqueous medium containing a hydrophilic colloid, e.g. gelatin. The hydrophobic materials include photographic addenda such as color couplers or solid particle dyes. Preferred dispersants have the general formula R—L—T   (1) or in which R, R1 and R2 are each independently selected from aliphatic hydrocarbyl, aryl-(aliphatic hydrocarbyl) and (aliphatic hydrocarbyl)-aryl groups, L is a sulphur atom or a linking group that contains a sulphur atom attached to the T group, and T is a hydrophilic oligomeric group obtained by the oligomerisation of one or more vinyl monomers having an amido function.
