| titleOfInvention | ARYLHYDRAZIDE-CONTAINING PHOTOGRAPHIC SILVER HALOGENIDE MATERIALS |
| abstract | Aryl hydrazides Ar-NR-NR1-G-X(+)A(-) (I) used in photographic Ag halide (AgX) materials for producing images with ultra-steep gradation; and new aryl hydrazides are of formula (IA) where Ar = substd. phenyl or another opt. substd. aryl gp.; G = CO, SO, SO2, PO2, PO3 or C=NR2; X(+) = a radical contg. a cationic gp.; R, R1 and R2 = H, 1-6C alkyl or 1-6C alkylsulphinyl; A- = an anion; R1-5 = 1-5 substit(s)., i.e. alkyl, hydroxyalkyl, haloalkyl, alkoxy, alkylamino, aliphatic acylamino or cycloalkyl with 1-20C; aryl, aryloxy or aromatic acylamino with 6-10C; aralkyl or aralkoxy with 1-3C in the alkylene chain; or a 1-4C aliphatic acylamino gp. substd. by phenoxy, opt. with 1-10C alkyl substit(s). Q(+) = trialkylammonium, pyridinium-1yl or N-alkylpyridinium-m-yl with m = 2, 3 or 4 or thiazolinium-3-yl or N-alkylthiazolinium-m-yl with m) 2,4 or 5, in which thge heterocycle may have other alkyl substits. opt. with OH or SO3H substits. with max. 12C; in the case of trialkylammonium, two gps. attached to the quat. N can form a 3-12 membered ring; B = a bridge with 1-3 methylene gps; opt. with Me or Et substits., or, if Q(+) = N-alkylpyridinium-m-yl or N-alkylthiazolinium-m-yl, B may also = O or a single bond; A(-) = anion, which is absent if Q(+) contains a SO3H gp. |
