Pigment formulations, processes for their preparation and their use

Abstract

The invention relates to readily dispersible pigment formulations which are stable to flocculation and are used for pigmenting naturally occurring and synthetic materials, preferably paints and printing inks, plastics and lacquers, in particular stoving lacquers. The pigment formulations contain compounds of the general formula (I) ##STR1## in which Q.sup.1, Q.sup.2 and Q.sup.3 each denote --X--A, --OR.sup.1, --SR.sup.1, halogen, --NR.sup.2 R.sup.3 or a radical Q which is built up from up to 15 trivalent groups (Ia) such that in each case one group (Ia) is bonded via W to a free valency of the next group (Ia) or to the triazine ring of (I) and the other free valencies are bonded to --X--A, --O--R.sup.1, halogen or --NR.sup.2 R.sup.3, at least one radical --X--A being present in (I), and A stands for an aromatic system with 2 to 6 rings and at least 9 ring atoms, or stands for a group of 2 to 3 aromatic ring systems, bonded via O, S, CO, SO, SO.sub.2 or C.sub.1 -C.sub.12 -alkylene, of in each case 1 to 4 rings, A optionally also being substituted by C.sub.1 -C.sub.24 -alkyl, OR', halogen, NR'R', COOR', CONR'R', NR'COR', CN, CF.sub.3 or NO.sub.2, and R' and R' denote H or C.sub.1 -C.sub.12 -alkyl or, with N, a heterocyclic radical with 5 or 6 ring atoms, X stands for NR*, O or S, in which R* denotes H, C.sub.1 -C.sub.6 -alkyl, -hydroxyalkyl or -alkoxyalkyl or C.sub.5 -C.sub.7 -cycloalkyl, R.sup.1, R.sup.2 and R.sup.3 each stand for H, alkyl, alkenyl, cycloalkyl, aralkyl, heteroalkyl, or phenyl, optionally substituted by C.sub.1 -C.sub.12 -alkyl, halogen, OR.sup.4, NR.sup.4 R.sup.5 COOR.sup.4, CONR.sup.4 R.sup.5, NR.sup.5 COR.sup.4, CN, CF.sub.3, NO.sub.2 or --T(CH.sub.2).sub.p NR.sup.o R.sup.t, in which R.sup.4 and R.sup.5 denote H or alkyl and R.sup.o and R.sup.t denote alkyl, p denotes 1-6 and T denotes a direct bond or O, S, CO, SO, SO.sub.2, NR.sup.a, NR.sup.a CO, NR.sup.a SO.sub.2, SO.sub.2 NR.sup.a or CONR.sup.a, and R.sup.a denotes H or C.sub.1 -C.sub.12 -alkyl, or stand for C.sub.1 -C.sub.12 -hydroxyalkyl or -polyhydroxylkyl or alkyl which is interrupted once or several times by O and/or NR.sup.v, in which R.sup.v denotes H or alkyl, and can be substituted by a 5- or 6-membered heterocyclic ring, or R.sup.1 has the above mentioned meaning and R.sup.2 and R.sup.3 together with N, stand for a 5- or 6-membered ring of a heterocyclic system with 1 or 2 rings, W is Y.sup.1 --Y--Y.sup.1, in which Y denotes alkylene, optionally interrupted by O, S, NH, N(alkyl), CO, SO, SO.sub.2, C.sub.5 -C.sub.7 -cycloalkylene, C.sub.5 -C.sub.10 -arylene or heteroarylene with 5-7 ring atoms or a 1-3-nuclear carbocyclic or heterocyclic ring system with 5 to 14 ring atoms or two of the ring systems, which are linked via a direct bond or O, S, CO, SO or SO.sub.2, and Y.sup.1 denotes O, S or NR.sup.5, in which R.sup.5 denotes alkyl, hydroxyalkyl, alkoxyalkyl or cycloalkyl or, together with N--Y--N, a heterocyclic ring. The dispersing agents used can be prepared by reaction of cyanuric halides with corresponding compounds H--X--A, HOR.sup.1, HSR.sup.1, HNR.sup.2 R.sup.3 and/or HWH.
