  • Dyeing automobile seat covers containing acrylic or cationic-dyeable polyester
    Patent number: 5824118
    Abstract: A dye which is durable for practical use in the field of coloring automobile seat materials for which a good light-fastness is required and a dyeing method making use of the dye is provided. In the method, a disazo dye is obtained by converting guanazole to a tetrazo compound and coupling the tetrazo with an indole derivative to form a compound which is then quaternized using e.g., an alkylating agent resulting in a red dye with superior light-fastness at high temperatures.
