| titleOfInvention | Colour development of photographic silver halide emulsion layers |
| abstract | 931,018. Colour development. AGFA A.G. April 7, 1961 [April 8, 1960], No. 12681/61. Class 98 (2). Photographic colour material comprising at least one silver halide emulsion layer containing a colour coupler is reversal developed using a colour developer in the presence of a compound of formula wherein R, R<SP>1</SP>, R<SP>11</SP> and R<SP>111</SP> each represents an alkylene radical having 1-10 carbon atoms or R and R<SP>111</SP> each represent a phenylene radical, m is 0-100, n is 1-50, p is 1-2, q is 1-100 and X is a hydrogen atom, an alkyl radical with 1- 10 carbon atoms which may be substituted by an amino, carboxyl, sulphonic acid or phosphonic acid group, an aryl radical which also may be substituted as above or an aliphatic mono- or di-carboxylic acid radical and in which compounds some of the sulphur atoms may be oxidized to sulphoxide or sulphone groups or alkylated to sulphonium groups. The material may be treated with a bath containing the above compound without making a second exposure and then colour developed in the normal way. Specified compounds are the condensation products of mono- or di-thiodiethylene glycol with polyethylene and polypropylene oxides and such compounds with the terminal hydroxyl groups esterified or etherified. Specifications 647,911, 859,632, 895,674 and 896,999 are referred to. |
