Abstract
1,238,573. Processing photographic silver halide materials. FUJI SHASHIN FILM K. K. April 21, 1969 [April 19, 1968], No.20325/69. Heading G2C. An exposed photographic light-sensitive silver halide material is hardened by treatment with a processing bath, e.g. a prehardener or developing bath containing formaldehyde and a compound of the general formula: - wherein R and R<SP>1</SP> are each hydrogen, alkyl or 1-5 carbon atoms or a water-solubilizing group, e.g. - SO 3 H, -COOH, -OH or the K, Na or NH 4 salts thereof. Compounds specified are phthalaldehyde, isophthalaldehyde, terephthalaldehyde; 4-hydroxy- and 4:5-dimethyl-phthalaldehyde; 2-hydroxy-, 4-hydroxy-, 2:4-, 4:5- and 4:6-dihydroxy-, 2-hydroxy-5-methyl-, 4-hydroxy-5-methyl-, 5-methyl-, 4:6-dimethyl-, 4-sulpho- and 4:6- dicarboxy-isophthalaldehyde; and 2-methyl-, 2:5-dihydroxy- and 2:5-dicarboxyterephthalaldehyde.
