Abstract
Trinuclear polymethine merocyanine dyes are prepared by reacting a compound of the general formula <FORM:0638047/IV (c)/1> wherein R1 is an alkyl, hydroxyalkyl, acyloxyalkyl, aralkyl, hydroxyaralkyl, or acyloxyaralkyl group, R2 is H or a hydrocarbon group, R3 is an alkyl or aralkyl group, X is an acid radical, Q is O or S, n is 0 or 1, and D1 is the residue of a 5- or 6-membered heterocyclic nitrogen nucleus, with a heterocyclic nitrogen compound containing a reactive methylene group. [2 - (3 - Ethylbenzthiazole) - 51 - (3-ethyl-2-thio - 4 - ketotetrahydrothiazole) - g .211 - (1-ethylquinoline) - tetramethinemerocyanine] iodide is prepared by boiling 1-ethylthio-2-a -quinolyl-3-(31 - ethyl - 21 - thio - 41 - ketotetrahydrothiazolylidene)-propene ethiodide and 2-methylbenzthiazole ethiodide in pyridine. [2-(3-Ethylbenzthiazole) - 51 - (3 - ethyl - 2 - thio - 4 - ketotetrahydrothiazole) - g .211 - (1 : 3 : 3 - trimethylindolenine) - tetramethinemerocyanine] iodide, [2-(3-ethylbenzthiazole) - 51 - (3 - methyl - 2 - thio - 4 - ketotetrahydrothiazole) - g .211 - (3 - ethylbenzoxazole) - tetramethinemerocyanine] iodide, [2 - (1-ethylquinoline) - 51 - (3 - ethyl - 2 - thio - 4 - ketotetrahydrothiazole) - g .211 - (1 - ethylquinoline)-tetramethinemerocyanine] iodide, and bis - 5-(3-ethyl - 2 - thio - 4 - ketotetrahydrothiazole) - b - 21-(1 - ethyldihydroquinoline) - trimethinemerocyanine are similarly prepared. Specifications 549,202 and 638,021 are referred to.
