    摘要： A process for tinting a molded article is disclosed. The process entails applying by spraying or by flow coating a hot, dye-solution onto at least a portion of the surface of a molded article to obtain a tinted article and washing the tinted article. In addition to the dissolved dye, the dye solution that is substantially free of particulate matter contains an aqueous solution of an organic solvent and a surfactant. The article is one molded of a thermoplastic molding composition. In an embodiment of the invention, the dye solution is prepared by filtering a hot aqueous solution through a bag filter that contains a dye to obtain a hot, dye-solution. In a further embodiment, activated carbon is used to purify the dye solution to obtain a dye-free aqueous solution.

    摘要： Process for the single-bath dyeing of cellulose fibers and their mixtures with synthetic fibers with water-insoluble azo dyestuffs produced on the fiber according to the exhaustion method, wherein an aqueous dyebath is allowed to act on the textile material, at room temperature or moderately elevated temperature, which liquor contains, in addition to alkaline substances, sodium nitrite and an anionic dispersing system, the solution or dispersion of at least one component capable of entering into azo coupling and at least one non-diazotized primary aromatic amine in a medium on the basis of a water-miscible organic solvent or solubilizer, and after absorption of the coupling component, the diazotization of the amine and the dyestuff formation by coupling is caused in that acid or acid salts are added to the dyeing bath at room temperature.
