Abstract
Abstract This invention relates to a black dye formulation capable of high concentration in solution which imparts light fast, rich bloomy black shades found to be particularly desirable for printing and dyeing of textiles composed of cationic fibers, such as acrylics nylon, dacrons, polyesters, acetates, or mixtures thereof which formulation consists essentially of a triarylmethane dye portion and a methine dye portion combined in a ratio between about 1:1.2 and 1:2.8 and wherein the triarylmethane portion is composed of C.I. Basic Blue 1 or a mixture of C.I. Basic Blue 1 and C.I. Basic Blue 5 and the methine portion is composed of a mixture of C.I. Basic Violet 16; C.I. Basic Yellow 29 and C.I. Basic Orange 21. This novel dye formulation is prepared as a solution or liquid paste composition by diluting the above formulation with between about 25% and about 70% by weight of an inert solvent solution, which preferably contains water and a water miscible thiodialkylene glycol solvent having between 2 and 4 carbon atoms in the alkylene group. These liquid compositions may additionally contain other solvents, or additives which are conventionally incorporated in dye pastes.
