| 摘要 | 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. |
