摘要:A process for the preparation of a disperse methine dye containing at least one dicyanomethylidene group comprising the steps of (A) preparing an anhydrous solution of an aldehyde formed by contacting an aromatic amine, 1,2,3,4-tetrahydroquinoline or benzomorpholine compound capable of undergoing the Vilsmeier-Haack reaction with POCl3 and a N,N-di-alkylformamide wherein the alkyl moiety is 1-4 carbon atoms; (B) subsequently adding to said solution at least one equivalent of cyanoacetamide based on the equivalents of aldehyde formed in (A), thereby forming a reaction mixture of aldehyde and in situ generated malononitrile; and (C) adjusting the pH of the solution to a point sufficient for the condensation of the aldehyde and in situ generated malononitrile to occur thereby producing a disperse methine dye.
