    摘要： ANTHRAQUINONE DYESTUFFS WHICH ARE HALF SULPHURIC ESTERS OF COMPOUNDS OF THE FORMULA:

    1-((Y-PHENYL)-NH-),3-Z,4-(X-HN-)ANTHRAQUINONE

    WHEREIN THE AROMATIC NUCLEUS A MAY BE SUBSTITUTED BY HALOGEN, LOWER ALKYL OR LOWER ALKOXY IN ADDITION TO THE SUBSTITUENT Y;

    X REPRESENTS HYDROGEN, LOWER ALKYL, CYCLOHEXYL OR BENZYL; Y REPRESENTS HYDROXY LOWER ALKYL, HYDROXY LOWER ALKOXY LOWER ALKYL OR HYDROXY LOWER ALKYLTHIO; AND Z REPRESENTS HYDROGEN, HALOGEN OR LOWER ALKYL.

    THE DYESTUFFS GIVE FAST BLUE SHADES ON NYLON.

    摘要： ANTHRAQUINONES SUBSTITUTED IN THE 1 POSITION BY AN AMINO OR ALKYLAMINO GROUP, IN THE 4 POSITION BY A HYDROXY, ETHER, THIOETHER, AMINO OR SUBSTITUTED AMINO GROUP AND IN THE 2 POSITION BY A PHENOXY OR PHENYLTHIO GROUP CARRYING A PRIMARY, A SECONDARY OR TERTIARY AMINO GROUP ARE PREPARED FROM THE CORRESPONDING ANTHRAQUINONES SUBSTITUTED IN THE 2 POSITION BY A HALOGEN OR SULPHONIC ACID GROUP BY REACTION WITH THE APPROPIATE PHENOL OR THIOPHENOL, AND ARE CONVERTED INTO THEIR QUATERNARY SALTS BY ALKYLATING AGENTS. THE PRODUCTS, BEFORE OR AFTER QUATERNISATION, ARE USEFUL FOR THE COLORATION OF POLYMERIC MATERIALS.
