Abstract
796,020. Photographic colour development. AGFA AKT.-GES., '[formerly AGFA AKT.-GES. FUR PHOTOFABRIKATION]. .July 8. 1955 [July 8, 1954], No. 19855/55. Class 98(2) The colour development of exposed silver halide emulsion layer with colour developing agents in the presence of colour couplers is performed in the present of 1 - (p - aminophenyl) - 3 - aminopyrazoline or a derivative thereof wherein either or both of the p - amino group or the 1 - phenyl nucleus is substituted, which may be incorporated either in the colour developing solution or in the photographic emulsion. The pamino group may be substituted by an alkyl or acyl group and the 1 - phenyl group may be substituted by halogen or by an alkyl or alkoxy group replaced by at least one substituent, e.g. a halogen atom or an alKyl, aralkyl, aryl, acyl or alkoxy group. Examples of such derivatives are 1 - p - methalaminophenyl - 3 - animonpyrazoline, 1 - p - methenesulphonamidophenyl - 3 - aminopyrazoline, and 1 - (4' - ethylamino - 3' - methylphenyl) - 3 - aminopyrazoline. The 1 - (p - aminophenyl) - 3 - aminopyrazolines which are substituted in the amino residue are not themselves colour developers. From 1 to 10 per cent by weight of the compound, based on the colour developing substance, may be used. In Examples 1 and 2, an exposed "Agfacolor" (Registered Trade Mark) film is developed in (1) a developer containing 4 - amino - N - ethyl : N -# - hydroxyethyl - aniline, 1 - (4<SP>1</SP> - methylsulphonamidophenyl) - 3 - aminopyrazoline, potassium carbonate, and sodium sulphite, or (2) 4 - amino - N : N - diethylaniline, 1 - (4<SP>1</SP> - methylaminophenyl) - 3 - aminopyrazoline hydrochloride, potassium carbonate, potassium bromide, and sodium sulphite. In Example 3, an exposed film is developed in a solution containing 4 - amino - N - ethyl : N - # - hydroxyethylanilihe, 1 - (4<SP>1</SP> - acetylaminophenyl) - 3 - aminopyrazoline, 1 - hydroxy - 4 - sulpho - 2 - naphthoylanilide, potassium carbonate, potassium bromide, and sodium sulphite. In Examples 4 and 5, exposed material containing 1 - hydroxy - 4 - sulpho - 2 - naphthyl - N - stearylanilide and, in Example 4, 1 - (4<SP>1</SP> - methylaminophenyl) - 3 - aminopyrazoline hydrochloride, is developed in a solution containing (4) 4 - amino - N - ethyl. : N - # - hydroxyethyl - aniline, potassium carbonate, and sodium sulphite or (5) 4 - amino - N : N - diethylaniline, 1 - (p - methenesulphonylamino - m - ethoxyphenyl) - 3 - aminopyrazoline, potassium carbonate, sodium sulphite, and potassium bromide. In Examples 7 and 8, exposed subtractive multilayer colour films are developed in developers containing 4 - amino - N : N - diethylaniline, potassium carbonate, sodium sulphite, potassium bromide and (7) 1 - (4' - methylaminophenyl) - 3 - aminopyrazoline dihydrochloride or (8) 1 - (4<SP>1</SP> - amino - 3' - chlorophenyl) - 3 - aminopyrazoline dihydrochloride. In Examples 9 and 10, exposed subtractive multilayer colour films are developed in developers containing potassium carbonate, sodium sulphite, potassium bromide, and (9) 4 - amino - N - ethyl : N - # - hydroxyethyl - aniline and 1 - (4<SP>1</SP>- methanesulphonamido- 3<SP>1</SP> - methylphenyl) - 3 - aminopyrazoline or (10) 4 - amino - N butyl : N - # - hydroxyethyl - aniline and 1 - (4<SP>1</SP> - ethylaminophenyl) - 3 - aminopyrazoline dihydrochloride. Specifications 679,678 [Group IV(b)], 757,840, 776,322 [Group IV(b)], 778,657 and 795,476 are referred to.
