    摘要: 3'' - HYDROXY - QUINOPHTHALONE DYESTUFFS WHICH ARE FREE FROM SULPHONIC ACID GROUPS AND CROSSESPOND TO THE FORMULA

    2-(1-(O=),3-(HO-),6-(R1-N(-R2)-CO-)INDEN-2-YL),3-(HO-),

    (Z1)M,(Z2)N-QUINOLINE

    IN WHICH R1 AND R2, INDEPENDENTLY OF ONE ANOTHER, STAND FOR A C1C17-ALKYL RADICAL, WITH THE PROVISO THAT THE SUM TOTAL OF CARBON ATOMS CONTINUED IN R1 AND R2 AMOUNTS TO AT LEAST 16 PREFERABLY TO 16 TO 25; Z1 STANDS FOR A HALOGEN ATOM, A NITRO, C1-C4-ALKYL, C1-C4ALKOXY OR AN ACRYLAMINO GROUP; M IS A NUMBER FROM 0 TO 3; Z2 IS A FUSED BENZENE RING; AND N IS 1 OR, PREFERABLE, 0, AND A PROCESS FOR THEIR PRODUCTION. THE DYESTUFFS ARE ESPECIALLY SUITABLE FOR THE DYEING OF SYNTHETIC FIBER MATERIAL FROM ORGANIC SOLVENTS.
