Abstract
1379615 Photographic hardening bleach-fixing bath AGFA-GEVAERT AG 19 Jan 1972 [21 Jan 1971] 2625/72 Heading G2C A hardening, bleaching and fixing bath contains an organic aldehyde as a gelatine hardener, an iron (III) or cobalt (III) complex of a complex-forming aminopolyacetic acid as a bleaching agent and sodium thiosulphate as a fixing agent. The hardener may be an aliphatic mono- or di-aldehyde and may be formaldehyde or an aliphatic dialdehyde having 4-5C in which the carbon chain may contain an O, S or N atom, e.g. succinaldehyde, glutaraldehyde, bis- (formylmethyl) ether, bis- (formylmethyl) sulphide or bis- (formylmethyl) amine, the last mentioned being optionally substituted on the N atom by methyl, hydroxyethyl or formylmethyl. The aminopolyacetic acid may be nitrilotriacetic, an aliphatic or cycloaliphatic 1, 2- or 1, 3- diaminotriacetic or diaminotetraacetic acid. The bath may be used in the silver dye-bleach process (see Example 5).
