    Abstract: THIS INVENTION RELATES TO PHOTOGRAPHY, AND MORE PARTICULARLY, IT RELATES TO THE USE OF CERTAIN INDICATOR DYES DERIVED FROM INDOLES AS OPTICAL FILTER AGENTS TO PROTECT A SELECTIVELY EXPOSED PHOTOSENSITIVE MATERIAL FROM POSTEXPOSURE FOGGING IN PHOTOGRAPHIC PROCESSES WHERE DEVELOPMENT OF THE PHOTOSENSITIVE MATERIAL IS CONDUCTED IN THE PRESENCE OF EXTRANEOUS INCIDENT LIGHT. THESE INDICATOR DYES CONTAIN AN INDOLE RADICAL, A SECOND AROMATIC RADICAL AND A RING-CLOSING MOIETY BONDED TO THE AROMATIC RADICAL AND TO THE 2- OR 3-POSITION OF THE INDOLE RADICAL. AT A FIRST PH THEY HAVE A HIGHLY COLORED, LIGHT-ABSORBING FORM CAPABLE OF ABSORBING RADIATION WITHIN A PREDETERMINED WAVELENGTH RANGE IS THE SHORTER WAVELENGTH REGION OF THE VISIBLE SPECTRUM AND AT A SECOND PH HAVE A COLORLESS FORM THAT IS SUBSTANTIALLY NON-LIGHT-ABSORBING IN THE VISIBLE

    SPECTRUM. BY SELECTING A DYE FROM THIS CLASS WHICH IS IN ITS LIGHT-ABSORBING FORM AT THE PH AT WHICH DEVELOPMENT IS PERFORMED, PROTECTION OF THE EXPOSED PHOTOSENSITIVE MATERIAL FROM RADIATION ACTINIC THERETO IS AFFORDED WITHIN THE WAVELENGTH RANGE ABSORBED BY THE DYE AND SUBSEQUENT TO AT LEAST THE INITIAL STAGES OF DEVELOPMENT, THE DYE MAY BE RENDERED SUBSTANTIALLY COLORLESS BY ADJUSTING THE PH TO PERMIT VIEWING OF THE FINAL IMAGE.

    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).
