The invention relates to novel soluble pigment precursors possessing not only higher thermal stability but also improved solubility characteristics and to a process for mass coloration of high temperature polymers that utilizes these novel soluble pigment precursors.
The pigment precursors of the invention are essentially of the formula
A(B)x (I)
where
x is an integer from 1 to 8,
A is the radical of a chromophore of the quinacridone, anthraquinone, perylene, indigo, quinophthalone, indanthrone, isoindolinone, isoindoline, dioxazine, azo, phthalocyanine or diketopyrrolopyrrole series, this radical being linked with xB groups via one or more heteroatoms, these heteroatoms being selected from the group consisting of N, O and S and forming part of the radical A, and
B is hydrogen or a group of the formula
although at least one B group is not hydrogen and when x is from 2 to 8 the B groups may be identical or different. E1, E2, R1, R2, R3, R4, R7, R11, R14 and G1 are as defined in the specification.
Also claimed are some materials pigmented according to the invention.
该发明涉及一种新型可溶性颜料前体,不仅具有较高的热稳定性,而且具有改善的溶解特性,以及一种利用这些新型可溶性颜料前体进行高温聚合物的质量着色的方法。该发明的颜料前体基本上具有以下公式A(B)x(I)其中x是从1到8的整数,A是喹啉酮、蒽醌、苝、靛蓝、喹酮、靛基酮、异吲哚酮、异吲哚烷、二氧嗪、偶氮、酞菁或二酮吡咯吡咯烯系列的色团的基团,该基团通过一个或多个杂原子与xB基团连接,这些杂原子选自N、O和S组成的群,是基团A的一部分,B是氢或具有以下公式的基团,尽管至少一个B基团不是氢,当x为2到8时,B基团可以相同也可以不同。E1、E2、R1、R2、R3、R4、R7、R11、R14和G1如规范中所定义。还声明了根据该发明进行着色的一些材料。
