Compositions containing benzodifuranone compounds and methods for dyeing hydrophobic materials using the same.

摘要

The invention is to provide a composition made by blending a benzodifuranone compound of the formula (I): wherein R1 represents a methylene or straight or branched C2-C6alkylene group optionally substituted with a hydroxy, C1-C4alkoxy or C1-C4alkylcarbonyloxy group; and Q represents 5- or 6-membered saturated or unsaturated heterocyclic ring residue, with an anthraquinone compound of the formula (II): wherein R2 represents an optionally substituted C1-C6alkyl, optionally substituted phenyl or C1-C4alkoxyphenylsulfonyl group, and a method for dyeing hydrophobic materials using the composition to obtain red dyed products with excellent pH dependency and fastnesses to light and washing.
