This invention relates to a process for preparing perylene pigment compositions by
(a) reacting, at a temperature of less than about 25°C, a mixture of
(1) a perylene tetracarboxylic compound,
(2) at least about 0.1% by weight, relative to the perylene tetracarboxylic compound, of a surfactant of formula (I)
wherein R1, R2, R3, X, Y, Z, and Z' are defined herein,
(3) an equivalent excess, relative to the amount of the perylene tetracarboxylic compound, of ammonia or a primary amine RA-NH2, wherein RA is defined herein, and
(4) optionally, a solvent,
to form a perylene intermediate;
(b) heating the perylene intermediate at a temperature of about 50°C to about 250°C, optionally in the presence of certain non-pigmentary cyclic anhydrides or imides and/or solvents; and
(c) collecting the perylene pigment composition.
本发明涉及一种通过以下方法制备过烯颜料组合物的工艺
(a) 在低于约 25°C 的温度下,使下列物质的混合物发生反应
(1) 一种过烯四羧酸化合物、
(2) 相对于该过烯四羧酸化合物,至少约 0.1%(按重量计)的式 (I) 的表面活性剂
其中 R1、R2、R3、X、Y、Z 和 Z' 在此定义、
(3) 过量的氨或伯胺 RA-NH2(其中 RA 在本文中定义),其用量与过量的四羧基过烯烃化合物的用量相等;以及
(4) 可选的溶剂、
形成一种过烯中间体;
(b) 在约 50°C 至约 250°C 的温度下加热该过烯中间体,可选择在有某些非颜料环 酸酐或亚胺和/或溶剂存在的情况下进行;以及
(c) 收集过烯颜料组合物。
