摘要:<p>Surfactants useful as dispersing aids in the preparation of compositions comprising a hydrophilic colloid having hydrophobic particles dispersed therein have the structure <IMAGE> I wherein M is a cation; X represents a group having the structure <IMAGE> wherein each of R1, R2, R3 and R4 independently represents hydrogen or alkyl; or R1 and R2 taken together represent cycloalkyl; or R3 and R4 taken together represent cycloalkyl; and, n represents 0 or 1; provided that the total number of carbon atoms in each X group is 3 or 4, and when R1 is hydrogen R2 is other than methyl. Such surfactants offer coating and photographic property advantages when incorporated in multilayer photographic materials comprising a support bearing a plurality of hydrophilic colloid layers.</p>
