Abstract

1528463 Purine containing colour couplers AGFA-GEVAEBT 2 Dec 1975 [3 Jan 1975] 314/75 Heading C2C [Also in Division G2] A photographic ketomethylene yellow-forming colour coupler has a methylene group carrying a 2,6-dioxo-7-purinyl group in its oxo or enol form which may be substituted. The coupler may have the formula where Cp is a ketomethylene colour coupler residue linked through its active methylene group; each of R1 and R2 is H, optionally substituted alkyl or aryl; and R3 is H, OH, alkoxy, mercapto, cyclic amino, alkylthio, carboxy, alkoxycarbonyl, carbamoyl or optionally substituted alkyl, aryl, or amino. In all the specified couplers. R1 and R2 are CH 3 and R3 is H. α-(2-Hexadecyloxybenzoyl)-α-(1,3- dimethyl – 2,6 – dioxo – 7 – purinyl) – 21,51– dimethoxy – 41 – N,N – dimethylsulphamoylacetanilide is prepared by refluxing theophylline, tetramethylguanidine and α-chloro-α-(2- hexadecyloxybenzoyl)- 21,51 – dimethoxy- 41– N,N – dimethylsulphamoylacetanilide in acetonitrile. Other couplers are prepared similarly.
