<p>A waterless dye composition for apparel and other thermoplastic articles comprises an aromatic polyester of the formula C6Hz'-(COOR1)z, wherein z is 3, 4, 5, or 6; z' is 6 - z; and R1 is higher alkyl; and/or a cycloaliphatic diester of the formula <IMAGE> wherein R is substituted or unsubstituted straight or branched chain alkyl of 4-20 carbon atoms, polyoxyalkylene of the formula HO(CxHyO)nCxHy- or phosphated polyoxyalkylene of the formula (HO)2P(=O)O(CxH2xO)nCxH2x or a salt thereof, wherein (CxH2xO)n is (CH2CH2O)n, (C3H6O)n or (CH2CH2O)p- (C3H6O)q, n is 2-22, and the sum of p+q is n; and an organic colorant. A process for coloring apparel or other articles, fabricated from polyester, polyamide, polyurethane, acrylic, halogenated polyolefin or epoxy plastic, comprises exposing an article to the foregoing compositions, maintained at a temperature between 100 DEG C. and the temperature at which the plastic is degraded, for a time adequate to achieve the desired degree of coloration. The compositions may further be diluted with water and used for textile finishing processes or as dyeing assistants in aqueous baths.</p> |
