Colour photographic material with increased image dye stability towards light, heat and humidity

摘要

In colour photographic material with a base and blue-, green- and red-sensitive silver halide (AgX) emulsion layer(s) containing yellow, magenta and cyan coupler respectively and optionally other layers, at least one layer containing cyan coupler contains (a) a first type of dispersed particles containing the particular colour coupler in solution and (b) a second type of dispersed particles containing a 2-(2-hydroxyphenyl)- 4,6-diphenyl- 1,3,5-triazine of formula (UV-I) as ultraviolet (UV) absorber and/or an image stabiliser of formula Rc1-W-Rc2 (ST-I) or Rd1-Z (ST-II) and/or an oil former of formula O=P(O-Re1)3-s)(Re2)s (OF-I), Rf1-L-Y-Rf2 (OF-II), or Rg1-V-Rg2 (OF-III), or polymers (OF-IV) with repeating units containing a group of the formula -CO-K-, In the formulae, Rb1 = hydroxyl (OH), halogen, alkyl, alkoxy, aryloxy, alkylthio, arylthio, acyloxy, acylamino or acyl; Rb2 = hydrogen (H), alkyl, aryl or acyl; Rb3 = H or -ORb2; Rb4 = halogen, alkyl, alkoxy, aryloxy, alkylthio, arylthio, acyloxy, acylamino or acyl; o, p, q = 0, 1 or 2; Rc1, Rd1 = aryl or heterocyclyl; Rc2 = H, alkyl, aryl, heterocyclyl or acyl; W = -O-, -S-, -SO-, -SO2- or -NRc2-; Z = a nucleophilic group or a group releasing a nucleophilic group in the photographic material; Re1 = H, alkyl or aryl; Re2, Rf1, Rg1 = alkyl or aryl; s = 0 or 1; at least one Re1 group not = H; Rf2 = H, alkyl, aryl or acyl; L = -CO- or -SO2-; Y = -O- or -NRf2-; Rg2 = H or as Rg1; V = -O-, -S-, -SO-, -SO2-, -CO- or -NRg2-; Rc1, Rc2 and W, Rf1, Rf2, L and Y and Rg1, Rg2 and V may form a 5-8-membered ring; K = -O- or -NRh1-; and Rh1 = H, alkyl, alkylene, aryl, arylene or acyl.
