Abstract

Dyes having one of the general formulae:-<FORM:0749192/IV(c)/1> <FORM:0749192/IV(c)/2> wherein R1 and R2 are alkyl or aralkyl groups or together complete a carbocyclic ring such as cyclopentamethylene, R5 is an alkyl group, R6 is H or an alkykl group, R7 and R8 are alkyl groups, Y is an anion, m, n and p are O or I and D1, D2 and D3 complete heterocyclic nitrogen nuclei, are prepared by reacting the dyes of Specification 749,189 which have a reactive thioalkyl group on the 4 position of the iminazolenine ring with a compound of formula:- <FORM:0749192/IV(c)/3> where Z is an anion, or with a compound of formula:- <FORM:0749192/IV(c)/4> D1, and D2 may complete nuclei such as thiazoles, oxazoles, or selenazoles and their benzene or naphthalene homologues, pyridine, quinoline, naphthoquinolines, indolenines, pyrimodines, quinazolines, 1:3:4-thiadiazole, thiazolines and selenazolines, or, when n is O, iminazolenines. The carbocyclic rings of such nuclei may be substituted with alkyl, aryl, alkoxy or methylene dioxy groups or by halogen atoms. D3 may complete a rhodanine, oxarhodanine, oxindole, 5-pyrazolone, hydantoin, thio-hydantoin, pseudohydantoin, pseudothiohydantoin, oxazolone or thiazolidone (including 21:11 - benziminazo - 2:3 - thiazold - 4 - one) nucleus. Specifications 734,793, 749,190 and 749,193 also are referred to. In the Provisional Specification, R1, R2 and R6 are defined as hydrocarbon groups, R7 and R8 (R9 and R10 in formulae in Provisional Specification) are defined also as arakyl and aryl groups and substituted alkyl groups are referred to in connection with R5 and R7 (R9) and R8 (R10). D1 and D2 may also complete acenaphthene or anthracene homologues of the thiazole, oxazole or selenazole series or nuclei of the oxazoline, pyrazolenine or triazole series. Reference is also made to reacting dyes of the formula:- <FORM:0749192/IV(c)/5> where R9 is alkyl, aralkyl or aryl, p is 1 or 3, D2 has the same significance as D3 above and the other symbols have the meanings given above, with a compound of formula IV or V above. The methine chain in formula VI and VIII above may also carry alkyl substituents in addition to R6.
