Abstract
1,194,051. Processing photographic silver halide colour materials. AGFA GEVAERT A.G. June 21, 1967 [July 2, 1966], No.28636/67. Heading G2C. Exposed photographic silver halide colour material is processed by colour-developing, bleaching and fixing, a treatment with a bath containing a black- and-white developing agent being given after the colour development step. Black-and-white developing agents specified are P-amino-phenol or derivatives thereof and 1-phenylpyrazolidones, and the bath may also contain antioxidants such as hydroxylamine, sequestering agents such as sodium hexametaphosphate, stabilizers such as potassium bromide and alkali such as sodium or potassium carbonate or alkali-metal phosphates, borates or hydroxides. The colour sensitivity of the material is increased.
