    Abstract: The Specification relates to methine dyes of the general formula: wherein R1 is hydrogen, chlorine, bromine, alkyl, alkoxy, hydroxy alkoxy, amino, acetylamino, benzoylamino, nitro, sulphonamido, alkylsulphonamido, alkyl sulphonyl, alkylsulphonylamino, phenylsulphonylamino, phenyl or carbalkoxy, or represents a fused-on benzene ring, R3 is hydrogen or alkyl, R41 is a cyano, acyl or carbalkoxy group and R5 is the residue of a 5-pyrazolone, cyanacetic acid or an alkyl ester, substituted alkyl ester or amide thereof, or of malonic acid dinitrile, the residue R5 being free from sulphonic acid groups and all the said alkyl and alkoxy groups containing from 1 to 5 carbon atoms. The dyes are prepared by condensing a compound R5H2 with a 3;3-dimethyl-2-methylene -indoline-o -aldehyde having also an o -cyano, acyl or carbalkoxy substituent (R41), preferably in an alkaline medium. An emulsifying agent such as polyoxyethylene oleyl ether also may be present. In the case where R5 is the residue of a 5-pyrazolone, the dyes may be prepared by reacting a 3;3-dimethyl-2-methylene-indoline having an o -cyano, acyl or carbalkoxy substituent (R41) with a 5-pyrazolone having in its 4-position a -CHO or =CH-N(alkyl)2 group, preferably in an acidic medium. Dyes are specified wherein the substituent R1 in the indoline component is methyl, methoxy, carbomethoxy or chlorine. Pyrazolone components are specified having a 1-phenyl, chlorophenyl, dichlorophenyl, nitrophenyl, or methylphenyl substituent and a 3-methyl or carboxylic acid, ester or amide substituent. The group R41 may be cyano, benzoyl or carbethoxy. Specification 929,394 is referred to.

    Abstract: Cyanine dyes are prepared by reacting a 2-cyanmethylene-indoline of the formula wherein n is 0 or 1, A is an ortho phenylene or ortho naphthalene residue, R is H or CN, X is a dialkylated carbon atom and Y is N-alkyl, with a 1; 3; 3-trialkyl-2-methylene-indoline-o -aldehyde, an indole-3-aldehyde or a p-di-substituted aminobenzaldehyde in the presence of an acidic condensing agent. Examples are given of the preparation of trimethine dyes by reacting a 1-methyl- or 1-ethyl-3; 3-dimethyl-2-cyanmethylene-indoline which may have methyl, methoxy, chloro, carbomethoxy or phenyl substituents in the benzene ring, with a 1; 3; 3-trimethyl-2-methylene-indoline-o -aldehyde which may have methyl, methoxy, or chloro substituents in the benzene ring, or with 1-ethyl-3; 3-dimethyl-5-ethoxy-2-methylene-indoline-10-aldehyde. Other 2-methylene-indoline-w-aldehyde starting materials are referred to including ones having in the 5-position a nitro, carboxylic amido or ester, cyano, acylamino, alkylsulphonylamino, arylsulphonylamino or sulphonamido substituent. In Example 11, an a -g -dicyano-pentamethine dye is prepared from 1; 3; 3-trimethyl-2-(a -g -dicyano-propenylidene)-indoline and 1; 3; 3-trimethyl-2-methylene-indoline-o -aldehyde. In Example 12, a dimethine dye is prepared from 1; 3; 3-trimethyl-2-cyanmethylene - indoline and 1 - methyl - 2 - phenyl - indole-3-aldehyde. In Example 13, a styryl dye is prepared from 1; 3; 3-trimethyl-2-cyanmethylene - indoline and p - dimethylamino - benzaldehyde; reference is made to using p-(N-methyl - N - phenylamino) - or p - (N - methyl - N - (p1 - methoxyphenyl) - amino) benzaldehydes. The reactions may be carried out in benzene, ligroin, cyclohexane, chloroform, chlorobenzene, acetone or acetic acid as solvent, and with phosphorus oxychloride, thionyl chloride, acetyl chloride, acetic anhydride, sulphuric acid or phosphoric acid as acidic condensing agent. Specifications 823,520 and 897,195 are referred to.
