Abstract

1,274,302. Photographic silver halide materials containing silica particles. AGFAGEVAERT. Sept. 10, 1969 [March 17, 1969], No. 13884/69. Heading G2C. A photographic material comprises a support, a light-sensitive silver halide emulsion layer and a non-light-sensitive hydrophilic colloid protective surface coating which is coated at the same side of the support as the said emulsion layer and contains dispersed therein silica particles wherein said material contains in one of its hydrophilic colloid layers resorcinol and in the same or other hydrophilic layer a poly-N-vinyl lactam or polyvinyl lactone and the said hydrophilic protective surface coating also contains a polycarbocyclic aromatic (i.e. two or more benzene rings fused together, or at least two aromatic rings directly joined together or joined by an aliphatic or carbocyclic aromatic group which groups may be interrupted by one or more hetero atoms) sulphoric acid or a water soluble salt thereof, preferably of the formula:- wherein M is H, a water-solubilizing metal cation or ammonium, B 1 is H, a fused aromatic ring which may be substituted, or an amino group which may be substituted, A is alkylene, alkenylene or bisamido, and B 2 is an aromatic group which may be substituted. Resorcinol is preferably present in the light-sensitive silver halide emulsion layer, and the poly-N-vinyllactam or polyvinyllactone is preferably present in the non- light-sensitive hydrophilic colloid protective surface coating. The poly-N-vinyl lactam is preferably poly-N-vinyl-2-pyrrolidone and the preferred polyvinyl lactone is poly-N-vinyl-2- oxazolidone. These compounds are anti-foggants. The average silica particle size is preferably less than 1 micron. The hydrophilic colloid of the surface coating is preferably gelatine. The silver halide emulsion layer may be a gelatino silver halide X-ray emulsion layer and the material may be an X-ray film having both sides coated as above. The milkiness and cloudiness produced by resorcinol and a polyvinyl lactam or lactone is reduced or eliminated by the presence of silica and a polycarbocyclic aromatic (as defined above) sulphonic acid or water-soluble salt thereof in the surface coating.
