Abstract

Dyes having one of the general formulae:-<FORM:0749193/IV(c)/1> 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 an alkyl or hydroxyalkyl group R7 is an alkyl group, Y is an anion, m, n and p are O or I and D1, D2 and D3 complete heterocyclic nitrogen rings, are prepared by reacting the dyes of Specification 749,190 having a reactive methyl group on the 2 position of the iminazolenine ring with a compound of the formulae:- <FORM:0749193/IV(c)/2> where Q represents a thioether, thioethervinyl, or acetanilidovinyl group, or with a compound of the formulae:- <FORM:0749193/IV(c)/3> where R8 is an alkyl group. D1 and D2 may complete nuclei of the thiazole, oxazole or selenazole series including their benzene and naphthalene homologues, or of the pyridines, quinoline, naphthoquinoline, indolenine, quinazoline, 1:3:4-thiadiazole, thiazoline, selenazoline or iminazolenine series. The carbocyclic rings of such nuclei may carry alkyl, aryl, alkoxy, methylene dioxy or halogen substituents. D3 may complete a rhodanine, oxarhodanine, oxindole, 5-pyrazolone, hydantoin, thiohydantoin, pseudohydantoin, pseudothiohydantoin or thiazolidone nucleus. Some of the dyes are also described in Specifications 734,793 and 749,192. The Provisional Specification relates also to dyes of the formulae:- <FORM:0749193/IV(c)/4> and <FORM:0749193/IV(c)/5> wherein the symbols have their usual significance. Most of the symbols, however, are defined in terms wider than those of the corresponding symbols in the Complete Specification. Compounds of formulae III may be employed but having a reactive =CHOH or =CHNHC6H5 group. Specification 743,133 also is referred to.
