Compositions and methods useful for imparting coloration to various substrates including plastics, paper, wood, fabrics, fibers and textiles. Materials comprising water-soluble colorants including an amidine group and a chromophore moiety are contacted with a substrate, and the substrate permitted to dry to provide substantially water-proof coloration on the substrate. In one embodiment an ink, coating, or dye is an aqueous composition comprising one or more amidines as provided herein, which is contained within a vessel that includes a gas at an effective level of pressure to enable the gas to react with an amidine as herein provided, to provide and maintain the amidine substantially in its protonated form prior to application of the aqueous composition to a desired substrate.
