Methods for coloration of substrates, including textiles, by plasma polymerization of dyes to which polymerizable moieties have been chemically bonded at sites on the dye capable of bonding to such moieties, and that have been deposited on at least one surface of the substrate, are described. Atmospheric pressure plasmas were used for the polymerization process. Generally, the plasma polymerization is performed away from the dye deposition so that undeposited dye is not exposed to the plasma. Textiles may include cotton, polyester, wool, silk, acrylics, polypropylene, polyolefins, aramids, and nylon, and blends thereof. The plasma-polymerizable moiety may be chosen from acrylates, methacrylates, and vinyl amides. Dye functional groups may include hydroxyl groups, carboxyl groups, amines: primary, secondary, and tertiary, epoxides, carboxylic acids, and chlorides, and dyes may include acid dyes, disperse dyes, azo dyes, vat dyes, sulfur dyes, direct dyes, reactive dyes, basic dyes, pigment dyes, aniline dyes, anthraquinone dyes, and coumarin dyes, as examples.
