A process of producing a monoazo lake pigment comprising the steps of:
a) diazotizing an aromatic amine having to produce a water soluble group to produce a diazo component;
b) coupling the diazo component with a coupler component; and
c) conducting laking after or simultaneously with the coupling step b, thereby forming a laked pigment aqueous slurry,
wherein the laking is carried out in the presence of 0.1 to 40 parts by weight of a water-soluble acrylic polymer per 100 parts by weight of the coupler component.
一种生产单偶氮湖颜料的方法,包括以下步骤:a)重氮化具有水溶性基团的芳香胺以产生一种重氮组分;b)将重氮组分与偶合剂组分偶联;以及c)在偶联步骤b之后或同时进行湖化,从而形成湖颜料水浆,其中在每100份偶合剂组分中存在0.1至40份重量的水溶性丙烯酸聚合物的情况下进行湖化。
