摘要

Formulation for paste dyes for paints and decorative coverings comprising at least water, glycols, mineral charge, biocides, pH stabilizers, at least one organic or inorganic pigment and a combination of wetting and dispersant additives. The additives are chosen from the family of polyesters modified with fatty acids having a molecular weight of between 1000 and 3000 g/mol, an acid value of between 35 and 60 mg KOH/g, an amine value of between 30 and 65 mg KOH/g, provided with at least two polar heads based on amines of the tertiary type, the family of polyesters modified with fatty acids having a molecular weight of between 1000 and 3000 g/mol, an acid value of between 10 and 34 mg KOH/g, an amine value of between 20 and 45 mg KOH/g, provided with polar heads based on amines of the tertiary type, the family of emulsifiers based on fatty acids C16 and C18 unsaturated and esterified with polysaccharide esters, the family of poly-carboxylate or poly-acrylate poly-anionic polymeric dispersants, the family of non-ionic additives based on ethoxylate or propoxylate alcohols C6-C12.
