Abstract
Abstract A process for pigmenting organic material of high molecular weight, which comprises the use of a compound of the formula ##STR1## in which X is a meta- or para-positioned fluorine, chlorine or bromine atom. The yellow to scarlet colorations obtained are distinguished by excellent fastness to light and atmospheric influences.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
92 words
A pigmented composition comprising (a) a high-molecular weight polymer lacquer resin selected from the group consisting of an alkyd-melamine-formaldehyde resin, an alkyd-urea-formaldehyde resin, a thermoplastic acrylic resin, a thermoset acrylic resin, an epoxy resin and a polyurethane resin, into which is incorporated (b) an effective amount of a finely dispersed pigment compound of formula I ##STR3## in which X is a meta- or para-positioned fluorine, chlorine or bromine atom, which pigment compound has a specific surface area of at least 10 m 2 /g and which compound is insoluble in said polymer.
