Abstract: BASIC DYES OF THE INDAZOLE SERIES OF THE FORMULA

(1,2-DI(A-),3-(K-N=N-),R3-1H-INDAZOLE)(+) X(-)

WHEREIN A IN METHYL, ETHYL OR A HYDROXYETHYL GROUP WHICH MAY BE FURTHER SUBSTITUTED WITH THE PRIVOSO THAT NOT MORE THAN ONE A IS METHYL OR ETHYL, R2 IS HYDROGEN, METHYL, METHOXY, CHLORO, NITRO, OR SO2R WHERE R IS AN AMINO RADICAL OR AN ALKYL OR ARYL RADICAL K IS A NITROGENEOUS COUPLING COMPONENT WHICH COMPLETES THE DYE MOLECULE ACID FORM A DIAZACYANINE SYSTEM AND X$ IS A COLORLESS ACID ANION. THE ORANGE TO BLUE DYES HAVE EXCELLENT FASTNESS PROPERTIES AND ARE SUITABLE FOR DYEING ANIONICALLY MODIFIED TEXTILE FIBERS, PARTICULARLY ACRYLONITRILE POLYMERS AND POLYESTERS.

Abstract: Azo dyes of the diaminopyrimidine series which may be exemplified by the formula

OR

IN WHICH Y is an electron-attracting substituent such as nitro, cyano, methylsulfonyl or the like and B is hydrogen or a substituent such as an alkyl, benzyl or phenyl group. The phenyl diazo component may also contain additional substituents and other readily available diazo components may replace the phenyl diazo component. The amino groups may also be substituted by replacement of one or both hydrogen atoms. These dyes are useful as disperse dyes for synthetic fibers, particularly polyesters. The dyes give yellow to blue violet shades having excellent fastness properties.

Abstract translation: 二氨基嘧啶系列的偶氮染料可以由式OR IN示例，其中Y是吸电子取代基如硝基，氰基，甲基磺酰基等，B是氢或烷基，苄基或苯基等取代基。 苯基重氮组分还可以含有另外的取代基，并且其它容易获得的重氮组分可代替苯基重氮组分。 氨基也可以通过置换一个或两个氢原子而被取代。 这些染料可用作合成纤维，特别是聚酯的分散染料。 该染料产生黄色至具有优异坚牢度性质的蓝紫色阴影。
