IPC: G03C1/37
Filed: 1989-10-26
Abstract: PURPOSE:To prevent the elution of a antibacterial and mildew-proofing agent from hydrophilic colloidal layers on a base even after photographic processing and to prevent the impairment of image quality by bacteria and mildew even after long-term preserving after the processing by incorporating dispersion of hardly water-soluble antibacterial and mildew-proofing particles having a specific grain size into the hydrophilic colloidal layers. CONSTITUTION:The dispersion of the hardly water-soluble antibacterial and mildew-proofing agent particles having 0.05 to 10 mum average grain size is incorporated into the hydrophilic colloidal layers on the base. The term 'hardly water-soluble' signifies quantitatively that the solubility in water at 25 deg.C is <=1,000 ppm and qualitatively that the particles hardly dissolve even in the coating soln. of the photosensitive material and exist substantially as particles therein. The outflow of the antibacterial and mildew-proofing agent into a processing bath and washing bath from the inside of the hydrophilic colloidal layers constituting the silver halide photographic material is suppressed in this way and, therefore, the sufficient mildew-proofing effect is obtd. even if the amt. of the antibacterial and mildew-proofing agent to be added into the photosensitive material is little.
