6 Methylquinizarin was synthesized through the Diels-Alder reaction of naphthazarin or 5, 8-diacetoxy-1, 4-naphthoquinone with isoprene. Disperse dyes were prepared from 6-methyl-quinizarin, and their dyeing properties on acetate and Tetoron examined. The .Emax of these dyes in ethyl alcohol shifts to shorter wave length than that of the corresponding 1, 4-disubstituted anthraquinones. The colors of dyed cloth vary from violet to greenish blue. Their dyeabilities on Tetoron were as good as that of the corresponding 1, 4-disubstituted anthraquinones. The light fastness on acetate was better but that on Tetoron was worse than that of the corresponding 1, 4-disubstituted anthraquinones. Their wash fastness on acetate was good. The dyes which have bulky substituents or hydrophilic groups showed good sublimation fastness on Tetoron.
