ABSTRACT:
Novel red azo pigment--fortified latex compositions for use in printing inks. The novel pigment compositions have superior burn-out resistance and color strength. The novel pigment compositions are made by coupling orthanilic acid derivatives (including optionally, disulfonated amine derivatives) with B-napthal precipitating the metal salts and mixing with fortified latex dispersions. The fortified latex dispersion comprises a dispersed polymer phase in a dissolved polymer phase. The dispersed polymer is preferably a high molecular weight copolymer while the soluble polymer is preferably a low molecular weight acrylic copolymer containing carboxyl group functionality. The novel pigment compositions have superior color strength.
