Abstract: 1,243,048. Azo and anthraquinone dyes. INTERNATIONAL POLAROID' CORP. 23 July; 1968 [24 July, 1967], No. 1734/71 Divided out of 1,243,045. Heading C4P. [Also in Division C2] Mono-azo, dis-azo or anthraquinone dyes for photographic transfer processes are-of formula wherein A represents the atoms necessary to complete a benzene or naphthalene radical that may be further substituted; D is a monoazo, disazo or anthraquinone colour providing moiety, Z is hydrogen, chloro, bromo, carboxy sulpho, hydroxy, alkoxy, hydroxyalkyl, or an aromatic amino radical unsubstituted ortho to said amino group; Y is the residue'of an acid group forming an amide with and reducing the basic character of the nitrogen atom to which it is bonded; X is hydroxy; or when Z is an anilino or naphthylamino radical containing, a y-amino or p-hydroxy substituent but unsubstituted ortho to said amino group joined to the ring completed by A, X may also be hydrogen or a primary, secondary or tertiary amino group or an alkyl, aromatic or heterpcyclic substituent; R 1 is hydrogen, alkyl, cycloalkyl or substituted alkyl, and wherein the values of A, X, Z and R 1 are such that the compound is non-diffusible in alkaline photographic processing solution. The examples describe (1) reacting (2- hydroxy - 4 - amine-HCl - 5 - chloro - 4 1 - carbon-dodecylamide) diphenyl and 4- (2-naphthol- 1 - azo) benzene sulphonyl chloride (A) to form a dye of Formula (I) (2) reacting N'-(o-aminophenyl)-4-methoxy-3- (N 1 ,-dodecylamidoethyl) aniline (B) and sulphonyl chloride (A) to form a dye of Formula (XIX) (3) repeating (2) but using an octadecamido compound to form a dye of Formula (XX) (4) reacting diazotized sulphanilic and 1-phenyl- 3. - carbethoxy - pyrazolone - 5 to form 1- phenyl - 3 - carbethoxy - 4 - (p -,'ulphophenylaze)- pyrazolone-5 sodium salt which,is reacted with propylamine to form the corresponding 3-propylamido compound which is reacted with thionyl chloride to form the corresponding pchlorosulphonylphenylazo compound which is reacted with compound (B) to form a methoxy compound which is demethylated with BBr 3 to form a due of Formula (XXI) (5) 2 - amino - 4 - stearylamide. - N - (41.- methoxy - 3 1 - carboxyphenyl) aniline is reacted with 4 1 - (sulphonylchloride) - phenylazo - 2 - naphthol to form a methoxy compound which is demethylated to a dye of Formula (XVI).

Abstract: PHOTOGRAPHIC SYSTEMS FOR PREPARING COLOR TRANSFER IMAGES EMPLOYING A PHOTOSENSITIVE ELEMENT HAVING AT LEAST ONE LIGHT-SENSITIVE SILVER HOLDS EMULSION HAVING ASSOCIATED THEREAFTER A FIRST COLOR-PROVIDING MATERIAL WHICH A NORMALLY DIFFUSIBLE IN AN AQUEOUS ALKALINE PROCESSING MEDIUM AND A SECOND COLOR-PROVIDING MATERIAL WHICH IS NOT, WHEREIN THE PHOTOSENSITIVE ELEMENT IN EXPOSED AND THEREAFTER DEVELOPED, AS A FUNCTION OF DEVELOPMENT THE FIRST-NAMED MATERIAL IS SELECTIVELY IMMOBILIZED TO PROVIDE A FIRST IMAGEWISE DISTRIBUTION OF MOBILE AND DIFFUSIBLE COLOR-PROVIDING MATERIAL AND SAID SECOND-NAMED MATERIAL IS SELECTIVELY RENDERED DIFFUSIBLE TO PROVIDE A SECOND IMAGEWISE DISTRIBUTION OF MOBILE AND DIFFUSIBLE COLORPROVIDING MATERIAL IN AREAS CORRESPONDING TO SAID FIRST IMAGEWISE DISTRIBUTION, AND SAID TWO IMAGEWISE DISTRIBUTIONS OF MOBILE AND DIFFUSIBLE COLOR-PROVIDING MATERIAL ARE THEN TRANSFERRED TO A DYEABLE STRATUM TO IMPART THERETO A COLOR TRANSFER IMAGE. THE PHOTOGRAPHIC SYSTEMS ARE ALSO CHARACTERIZED AS EMPLOYING EXPOSED SILVER HALIDE TO CONTROL TRANSFER OF ONE COLOR-PROVIDING MATERIAL; AND UNEXPOSED SILVER HALIDE TO CONTROL TRANSFER OF THE OTHER.
