In a pigment compsn. contg. coated organic pigment particles, the coating comprises (a) 0.5-100 wt.%, pref. up to 20 wt.%, esp. 1-10 wt.% Ca, Mg, Al, Zn, Zr and/or Ti phosphate complex (I) and (b) 0.5-15 wt.%, pref. up to 10 wt.%, esp. up to 5 wt.% amine of formula (IIA) or ammonium salt of formula (IIB), all w.r.t. pigment. In the formulae X1-X4 = opt. substd. hydrocarbyl or H but X1, X2 and X3 are not all H and, if X1 and X2 is H, Me or Et, X3 is not -(CH2)k-O-CO-C(R9)=CH2 or its (co)polymer; k = 1-6; R9 = H or Me; and Y1 = an (in)organic anion. Also claimed are a method of producing the compsn.; and high mol. material pigmented with this, pref. a lacquer or printing ink, more esp. an automobile lacquer or special effect lacquer, esp. a lacquer in which (IIA), is a polyethylene-imine of Mw 2000-70000. |
