Abstract

947,790. Photographic silver halide materials. GEVAERT PHOTO-PRODUCTEN N. V. Oct. 23, 1961 [Oct. 24, 1960], No. 15322/63. Divided out of 945,340. Heading G2C. [Also in Divisions C2 and C3] A photographic silver halide emulsion or adjacent layer contains as sensitizer a compound obtained by condensing a polyoxyalkylene compound with a diepoxide of the formula:- R-(CH 2 ) n -R where R is a 2;3-epoxypropoxy group and n is 1 to 4. The condensation products of polyethylene glycol and 1;2-di (2<SP>1</SP>;3<SP>1</SP>-epoxypropoxy)- ethane or 1;4-di (2<SP>1</SP>;3<SP>1</SP>-epoxypropoxy)- butane are referred to. The emulsions may contain a stabilizer such as 7-hydroxy-5-methyl-S-triazolo- (2, 3a)- pyrimidine. Specifications 548,019, 592,676, 600,058, 748,745, 748,750, 789,823, 793,915, 920,637 and Belgian Specifications 493,464, 568,687, 571,916 and 571,917 also are referred to.
