Abstract

Pigment preparations comprising at least PA1 a) 5 to 80% by weight, based on the preparation, of pigment, PA1 b) a paste-making agent which is liquid at 20.degree. C. under normal pressure, PA1 c) an amine and/or salt thereof with an average molecular weight, determined as the number-average, of M.sub.n .ltoreq.500 g/mol and PA1 d) a homo- and/or copolymer of ethylenically unsaturated monomers or comonomers having an average molecular weight, determined as the number-average, of M.sub.n =10,000-100,000, are suitable for pigmenting organic macromolecular material, in particular polyurethane foams.
