Abstract
805,826. Photographic light - sensitive materials. ILFORD, Ltd. April 23, 1957 [June 7, 1956], No. 17580/56. Class 98(2) A photographic element comprises a gelatino silver halide emulsion layer and a supercoat colloid layer containing a condensation product of ethylene oxide capable of increasing the effective emulsion speed, either or both of the emulsion layer or supercoat containing an antifogging agent of the formula : where R is an alkyl group. The condensation product may be a direct polymer of ethylene oxide, or a produce obtained by condensing ethylene oxide with a phenol, a glycol, an aliphatic alcohol, a hexitol ring dehydration product, an alphatic acid, amine or amide, or castor oil. The antifoggant may be a 4-hydroxy-6-alkyl-1:3: 3a:7- tetrazaindene. The supercoat is said to have antistatic properties. Specifications 380,431, 380,851 [both in Group VI], 548,019, 592,676, 600,058, 748,745, 748,750 and 805,827 are referred to.
