ABSTRACT:
Surfactants useful as dispersing aids in the preparation of compositions comprising a hydrophilic colloid having hydrophobic particles dispersed therein have the structure ##STR1## wherein M is a cation; X represents a group having the structure ##STR2## wherein each of R.sup.1, R.sup.2, R.sup.3 and R.sup.4 independently represents hydrogen or alkyl; or R.sup.1 and R.sup.2 taken together represent cycloalkyl; or R.sup.3 and R.sup.4 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 R.sup.1 is hydrogen R.sup.2 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.
