Method for dispersing photographic additives

In a method for preparing a photographic material, wherein an oil-soluble photographic additive is dispersed in water or a hydrophilic colloid composition the improvement which comprises dispersing said oil-soluble photographic additive in water or a hydrophilic colloid composition in the presence of a polymer having a recurring unit represented by the following general formula (I):

• --(A).sub.x --o--(B).sub.y -- (I)
• wherein A represents a monomer unit of the formula (II):
• ##STR20## wherein R represents a hydrogen atom or a methyl group;
• m represents 0 or 1;
• M represents a cation;
• and X represents an alkylene group having 1 to 4 carbon atoms, an arylene group, an aralkylene group having 7 to 11 carbon atoms or a --CO--NH--Y-- group where Y is an alkylene group having 1 to 6 carbon atoms or a phenylene group;
• B represents a copolymerizable ethylenically unsaturated monomer;
• x is about 10 to 100 mol%;
• and y is about 0 to 90 mol%.
