| titleOfInvention | Method for preparing P.Y.97 permanent yellow pigment |
| abstract | The invention relates to a method for preparing a pigment, in particular to a method for preparing a P.Y.97 permanent yellow pigment, and mainly solves the technical problems that the preparation method in the prior art cannot be used for directly preparing the P.Y.97 permanent yellow pigment and currently, the produced P.Y.97 permanent yellow pigment has poor chromatic light, low yield and the like. The method comprises the following steps of: carrying out diazotization on 4-amino-2,5-dimethoxy-N-benzenesulfonyl amine; coupling 4-amino-2,5-dimethoxy-N-benzenesulfonyl amine with 4-chlorine-2,5-dimethoxy-N-acetoacetanilide; then carrying out post treatment, pressure filtration, drying and grinding on the materials; and finally packaging to obtain the finished product. |
