Abstract
Methine dyes of the general formula: <FORM:0856068/IV (c)/1> wherein X is H or one or more substituents or a fused benz or substituted benz ring, R1 is alkyl or substituted alkyl, D completes a 5- membered nucleus and m is 0 or 1, are prepared by condensing a coumarin -4- acetic acid with a compound of the formula: <FORM:0856068/IV (c)/2> wherein Q is a thioether, thioethervinyl or acetanilidivinyl group and Y is an anion. Examples are given of the condensation of coumarin -4-acetic acid or its 7-hydroxy, 7-methyl, 7-methoxy, 7- diethylamino, 6; 7- dimethyl or 5; 6- benz derivatives with quaternary compounds of formula III wherein D completes a benzthiazoline, benzexazoline, indolenine, 5- methylthio -1; 3; 4- thiadiazoline, 4; 4- dimethylpyrrolidine or thiazolidine nucleus. According to the Provisional Specification, D may complete a 6-membered nucleus and the central carbon atom of the trimethine chain (m=1) may have an alkyl or -S- alkyl substituent. Specification 743,133 is referred to.
