FIELD: paint materials based on pentaphthallic alkyd resins. SUBSTANCE: high degree of trituration can be attained by treatment of pigments during or prior to dispersion process with solutions of surface active agents to lyophilize the surfaces thereof. SAA are adsorbed on surfaces of pigments and render them wettable and dispersive in varnish and solvent. Composition comprises alkyd resin, pigments, siccative, solvent, SAA of cationically active group, e.g. catamine AB, the ratio of components being as follows (wt %): 55- 70 alkyd resin; 20-33 pigment; 1-3 siccative; 1-3 solvent; from 0.01 catamine AB. EFFECT: improved properties of the paint composition. |
