117 Fluorescent quinacridone pigments US319399 1994-10-06 US5561232A 1996-10-01 Zhimin Hao; John S. Zambounis; Abul Iqbal
Compounds of formulaA(B).sub.x, (I),whereinx is an integer from 1 to 4,A is the radical of a chromophore of the quinacridone, anthraquinone, perylene, indigo, quinophthalone, isoindolinone, isoindoline, dioxazine, phthalocyanine or azo series, which radical contains x N-atoms attached to B, preferably with at least one directly adjacent or conjugated carbonyl group,B is a group of formula ##STR1## and, if x is 2, 3 or 4, may also be one, two or three hydrogen atoms. The symbols Q, R.sub.1, R.sub.2, R.sub.3, R.sub.4, X, Y, Z, m and n, are as defined in claim 1. These carbamate group-containing soluble chromophores am distinguished by outstanding solid state fluorescence in the UV range as well as the by ease with which they can be converted to the corresponding pigments in the substrate in which they are incorporated.
118 Process for producing 4,4'-diamino-1,1,'-dianthraquinonyl pigments US921574 1992-07-30 US5320678A 1994-06-14 Hiroki Inoue; Toshiaki Kishimoto; Iwao Sakaguchi; Kunitoshi Takahashi; Yoshiaki Hayashi; Keisuke Ito
A desulfonation reaction mixture of 4,4'-diamino-1,1'-dianthraquinonyl-3,3'-disulfonic acid obtainable in a conventional manner is mixed in the form of an aqueous acid suspension with a surface active agent, followed by filtration, whereby filterability and flowability of the produced 4,4'-diamino-1,1'-dianthraquinonyl pigment are efficiently improved.
119 Anthraquinone vat dyes US5991 1987-01-21 US5028709A 1991-07-02 Jean-Marie Adam
The invention relates to vat dyes of the formula ##STR1## wherein [A] and [A'] and X are as defined in claim 1. The vat dyes of formula I are suitable for dyeing or printing a wide range of materials. Dyeings with good fastness properties are obtained in particular on cellulose material.
120 Process for the preparation of 1-aminoanthraquinones US110162 1987-10-19 US4770818A 1988-09-13 Eric Plattner; Gottfried Seifert; Tibor Somlo
There is disclosed a process for the preparation of 1-aminoanthraquinones from 5-nitro-1,4,4a,9a-tetrahydroanthraquinones with a basic reducing agent, which process is carried out under pressure in the temperature range above 100.degree. C. and in an aqueous-organic medium. The process affords very pure 1-aminoanthraquinone, which is, inter alia, an important intermediate.
