Abstract

1,157,914. Photographic materials. E.I. DUPONT DE NEMOURS & CO. Oct.24, 1967 [Oct.24, 1966], No.48227/67. Heading G2C. A photo-developable silver halide emulsion layer comprises silver halide grains, of average grain sizes 0À1 - 10Á, dispersed in a waterpermeable macromolecular organic colloid, and, based onthe silver halide, 0À05-15 mole per cent of molecular iodine or an iodide ion-yielding compound, and 0À0005-1 mole per cent of a gold salt. The layer may also contain up to 120 mole per cent of a water-soluble bromide, and up to 5 mole per cent of a water-soluble plumbous salt. The iodideion yielding compound may be an alkali metal or alkaline earth metal iodide, NH 4 I, PbI 2 or organic iodides which will release I<SP>-</SP> by metathesis with the silver halide, e.g. an acyl, alkyl or quaternary ammonium iodide. The gold salt may be a gold halide, complex gold halide or other complex gold salt, or auric sulphate, many of which are listed. The soluble halide may be a halide of Li, Na, K, Ca, Hg or ammonium. The layer may contain a sensitizing dye, some of which are exemplified, and the usual binders and supports may be used. After imagewise exposure, the material may be kept in the dark, e.g. for 1 - 18 secs, with or without heating, to allow autolatensification to take place, and then photo-developed or it may be directly developed. The photo-developed material may then be further processed in a conventional silver halide developers and fixer to obtain a reversal image.
