Novel compositions based on C.I. Pigment Red 177
Abstract
Abstract A composition comprising (a) a dianthraquinonyl pigment of formula I ##STR1## (b) a compound of formula II ##STR2## wherein X.sup.⊕ is H.sup.⊕ or a group of formula M n ⊕ /n or N.sup.⊕ (R)(R 1 )(R 2 )(R 3 ), M n ⊕ is a monovalent metal cation of valency n, n is 1, 2 or 3, each of R, R 1 , R 2 and R 3 independently is hydrogen, C 1 -C 18 alkyl, C 5 -C 6 cycloalkyl, phenyl or phenyl which is substituted by C 1 -C 18 alkyl, or R 2 and R 3 , together with the linking nitrogen atom, are a pyrrolidine, imidazolidine, piperidine, piperazine or morpholine radical, or R 1 , R 2 and R 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.
