    摘要： Provided is a dye composition for keratinous fibers, which comprises (A) a hydrolyzate of a lower alkyl vinyl ether/maleic anhydride copolymer partially crosslinked with a terminal unsaturated diene compound, or a monoalkyl ester of the hydrolyzate; and (B) a dye.
    The dye composition for keratinous fibers according to the present invention has a stable and appropriate viscosity even in a wide pH range and even in a system containing a salt or solvent at a high concentration; and has excellent usability and dyeing properties. It is particularly suited for use with an acid dye.
