ABSTRACT:
A composition comprising
(a) a dianthraquinonyl pigment of formula I ##STR1## (b) a compound of formula II ##STR2## wherein X.sup..sym. is H.sup..sym. or a group of formula M.sup.n.sym.
or N.sup..sym. (R)(R.sub.1)(R.sub.2)(R.sub.3), M.sup.n.sym. is a monovalent metal cation of valency n, n is 1, 2 or 3, each of R, R.sub.1, R.sub.2 and R.sub.3 independently is hydrogen, C.sub.1 -C.sub.18 alkyl, C.sub.5 -C.sub.6 cycloalkyl, phenyl or phenyl which is substituted by C.sub.1 -C.sub.18 alkyl, or R.sub.2 and R.sub.3, together with the linking nitrogen atom, are a pyrrolidine, imidazolidine, piperidine, piperazine or morpholine radical, or R.sub.1, R.sub.2 and R.sub.3, together with the linking nitrogen atom, are a pyrrole, pyridine, picoline, pyrazine, quinoline or isoquinoline radical, r and t are each independently of the other 0 or 1, with the proviso that at least one of r and t must be 1.
Especially when used in varnishes pigment mixtures of this kind are distinguished in particular by enhanced color strength and high gloss and, most particularly, by improved rheology.
