Abstract (en)
[origin: EP0305926A1] A silver halide color photosensitive material is disclosed, characterized in that a lipophilic fine grain dispersed in at least one hydrophilic colloidal layer formed on a support contains at least one compound of formula (I) and at least one compound of formula (II): R1-SO2.M1 (I) R2-SO3.M2 (II) wherein each of R1 and R2 represents an aliphatic group having 8 or more carbon atoms, an aromatic group having 8 or more carbon atoms or a heterocyclic group having 8 or more carbon atoms; each of M1 and M2 represents a hydrogen atom or an inorganic or organic salt-forming atom or atomic group; also M1 represents a protective group to be hydrolyzed with alkali; and sodium dodecylbenzenesulfonate is excluded from the compounds of formula (II). the combined use of the compounds of formulae (I) and (II) can effectively control the formation of stains on the processed white ground after the lapse of time without substantially lowering the maximum color density.
