PIGMENTAL PASTE Russian patent published in 2008 - IPC C09D17/00 C09B67/00 C09D167/08 

FIELD: chemistry.

SUBSTANCE: invention relates to the pigmental paste for paint toning. The pigmental paste for toning the covering composition is described, where the pigmental paste includes: at least one ramified alkide with the viscosity less than 5 Pa·s at 23°C and shift rate 100 c^-1 and the number-average molecular weight M_n>1500, which contains the groups for the oxidising drying produced from the fatty acids; one or several solvents without aromatic substances - 28 mass percent; and one or several pigments. At that, the rate of alkide ramification is at least 0/35 and preferably less than 0.42, alkide fatness is at least 76 and preferably less than 84, the alkide acidity index is within 6 to 9 mg KOH/g; the solvent without the aromatic substances contains the aliphatic hydrocarbon solvents, ketones and/or complex ethers with molecular weight M_n>1500. The method for paint toning is described where the principal paint is selected from the set of principal paints and then mixed with the said pigmental paint, at that, the principal paint corresponds to the composition based on solvent and containing alkide.

EFFECT: invented pigmental paint is useful in toning paint with high concentration of solid substances.
