ジメチルアミノメチル基を有する染料

抄録

Several azo- and anthraquinone-dyes containing dimethylaminomethyl group were synthesized, and their dyeing properties were tested using several kinds of fibers.
Azo dyes were obtained by coupling 2-dimethylaminomethyl-1-naphthol (obtained by the reaction of α-naphthol with N, N, N', N'-tetramethyldiaminomethane) with diazonium or tetrazonium salts derived from aromatic primary amines.
Anthraquinone dyes were synthesized by the reaction of substituted or unsubstituted 1-amino-4-hydroxyanthraquinones with N, N, N', N'-tetramethyldiaminomethane in acetic acid in the presence of hydrochloric acid.
The dyes containing no sulfonic group readily dissolve in diluted acetic acid and dye acrylic fibers of Orlon type, and the dyes containing sulfonic group dye cotton in the presence of alkali by chemical combination.
