Abstract

1469763 Development of photographic silver halide materials MINNESOTA MINING & Mfg CO 13 June 1974 [13 June 1973] 28222/73 Heading G2C Exposed photographic silver halide materials, especially x-ray materials, are developed by contact with separate solutions comprising a non-alkaline solution or solutions containing at least one developing agent and at least one amine development accelerator which will not dye or stain the emulsion, and at least one alkaline solution. Preferably the material is contacted with a solution containing the developing agent and the development accelerator and then with an alkaline solution. Amine development accelerators include alkylene diamines from ethylene to hexylene diamine; trimethylamine; primary monoamines e.g. methylamine, propylamine, cyclohexylamine, benzylamine, aniline; heterocyclic amines e.g. piperazine, hexamethylene tetramine, pyrrolidine, 4-aminopyridine; aminoalcohols e.g. 3-aminopropanol, triethanolamine; and polyamines e.g. diethylene triamine, triethylene tetramine.
