Abstract

NEW MATERIAL:A benzopyran compd. of formula I, wherein R1 and R2 are each H, straight-chain or branched alkyl, halogen, cyano, (carbo)alkoxy, aryl (oxy), acetoxy-substd. alkyl, cycloalkyl or phenyl, where R1 and R2 may constitute a heterocyclic residue in combination with each other; X is imino or O; Y, and Y2 are halogen; m and n are 1W3 where m+n=2W4.
USE: A colorant for coloring a fiber or a molded product consisting of an org. high- molecular material in bright red with excellent fastness.
PREPARATION: It is obtd. by the reaction of an imino-coumarin of formula II with a malonodinitrile of formula III in an org. solvent (e.g.,dimethyl-formaldehyde) at 50W200°C, followed by hydrolysis in the presence of an acid, e.g., HCl.
