Abstract

1421123 α – (Aromatic acyl) – α – (diacylamino)acetamides FUJI PHOTO FILM CO Ltd 28 Dec 1972 [28 Dec 1971] 59952/72 Heading C2C [Also in Division G2] Novel yellow-forming colour couplers are α- (aromatic acyl) – α – (diacylamino) – acetamides preferably having the general Formula I: wherein R1 is an aryl group, R2 is an aryl group or a heterocyclic group and Z represents the non-metallic atom(s) required to complete a 4-6 membered ring and are prepared by reacting in an organic solvent the corresponding α- haloacetamide (4-equivalent coupler) with the corresponding imide or salt thereof in the presence of a base. Alternative preferred structures for the couplers are represented by the formulµ: wherein R1a and R2a each represents an arylene group or a group of formula -Y-Ya-Y-, wherein each Y represents an arylene group and Ya represents a divalent group (e.g. -CH 2 -, -O- and -NHCONH-) and R2a may also represent a heterocyclic group. In a preferred case, Z in Formula I is selected from the formulµ wherein R3-R20, R22-R25, R27-R34 and R38 and R39 are each independently H, halogen, sulpho, carboxyl, alkyl, alkoxy, aryl or aryloxy; or R3 and R5, R7 and R8, R9 and R11, R12 and R13, R15 and R16, R16 and R17, R24 and R25, R31 and R32 are combined together in said pairs to form saturated or unsaturated 5- or 6-membered fused rings; R21, R26, R35, R36 and R37 each independently represents H, optionally substituted C 1-32 alkyl or an aryl group; and W is -O- or -S-. Fig. 1 (not shown) comprises specific examples of imide residues comprising Z. At least one of R1, R2, R1a, R2a and Z may be substituted by a hydrophobic ballast group having 8 to 32 C atoms which renders the coupler diffusionresistant when present in a photographic emulsion layer. Specific examples of the yellow-forming couplers of Formula I are given in Fig. 2 (not shown). The 2-equivalent couplers are used in the processing of silver halide photographic emulsions in conjunction with an aromatic primary amino developing agent.
