PURPOSE:To reduce the sweating phenomenon of the titled material due to a lipophilic additive by incorporating the lipophilic additive for photography which is dispersed with a lipophilic surfactant without using a high boiling point org. solvent, in the hydrophilic colloidal layer of the titled material. CONSTITUTION:The titled material contains said additive which is dispersed with the lipophilic surfactant without using the high boiling point org. solvent in at least one layer of the hydrophilic colloidal layers. The lipophilic surfactant used for dispersing said additive in the hydrophilic colloidal layer without using the high boiling point org. solvent, is composed of an anionic surfactant having one of an aliphatic hydrocarbon group contg. at least 15 carbon atoms or having at least two aliphatic hydrocarbon groups contg. at least 17 total carbon atoms. Thus, the sweating phenomenon of the titled material due to said additive is improved. |
