Abstract

Cyanine dyes having one of the general formulae:-<FORM:0749189/IV(c)/1> <FORM:0749189/IV(c)/2> wherein R1 and R2 are alkyl or aralkyl groups, or together complete an aliphatic carboxylic ring such as cyclopentamethylene, R3, R5 and R7 are alkyl groups, R6 is H or alkyl, D1 and D2 complete heterocyclic nitrogen rings, n and m are 0 or 1 and Y is an anion, are prepared by reacting a compound of the formula:- <FORM:0749189/IV(c)/3> wherein X is an anion with a compound of the formula.- <FORM:0749189/IV(c)/4> wherein Q is a thio ether, thio ether vinyl or acetanilidovinyl group, or with a compound of the formula:- <FORM:0749189/IV(c)/5> The reactions are preferably carried out in the presence of a base such as pyridine, triethylamine, sodium acetate or sodium ethoxide. Instead of either of the above quaternary salts, the free bases may be used together with sufficient alkyl salt (R5 or R7Y) to convert them to the corresponding quaternary salts. D1 may complete a nucleus of the thiazole, oxazole or selenazole series, including their benzene and naphthalene homologues, or of the pyridine, quinoline, naphthoquinoline, indolenine, pyrimidine, quinazoline, 1:3:4-thiadiazole, thiazoline or selenazoline series, or, when n is O, D1 may be iminazolenine (i.e. by reacting two mols of a compound of formula III together, or by using a compound as described in Specification 734,792). The carbocyclic rings of such nuclei may carry alkyl, aryl, alkoxy, methylene dioxy or halogen substituents. D2 may complete a rhodanine, oxarhodanine, oxindole, 5-pyrazolone, hydantoin, thiohydantoin, pseudohydantoin, pseudothiohydantoin, oxazolone or thiazolidone (including 21:1 - benziminazo - 2:3 -thioazolid - 4 - one) nucleus. Some of the products are identical with those described in Specification 734,792. In the Provisional Specification, R1 and R2 are defined also as aryl, R6 as hydrocarbon and R7 (9 in the Provisional formula) as aryl or aralkyl. Additional values of D1 are given and merodicarbocyanine dyes similar to formula VII are referred to. Substituents on the methine chain in formula VI, other than R6, are indicated. Compounds of formula V may also be employed by having a reactive =CHOH or =CHNAC6H5 group. Specifications 743,133, 749,191 [Group IV(b)] and 749,192 also are referred to.
