Abstract

1,201,940. 940. Photographic silver halide emulsions. GAF CORP. Nov.15, 1967 [Nov.16, 1966; Aug.1, 1967], No.51936/67. Heading G2C. [Also in Division C3] A gelatine composition, such as a photographic silver halide emulsion, contains piperonal or is prepared using a gelatine which has been digested with piperonal. The gelatine may be bone gelatine or pigskin gelatine. In Examples, silver halide emulsions are prepared both using gelatine pretreated with piperonal and by adding piperonal at the chemical ripening stage. Other ingredients of the emulsions are gold thiocyanate, sodium thiosulphate, hydrazine, stannous chloride and thioacetamide.
