Abstract

FIELD: production of coatings for paper, mainly, painting inks. SUBSTANCE: polyol is modified by vegetable oil or its fatty. Modification product is subjected to reaction with dicarboxylic acid or its anhydride and rosin ester with acid number of 120-150 mg KOH/g and melting temperature of 130-145 C with consumption of rosin ester in the amount of 5-30% of mass of carboxyl-containing polyol oligoester. The latter is treated with di- or polyisocyanate in the medium of organic solvent. EFFECT: higher efficiency. 2 tbl

Область использования: изготовление покрытий для бумаги, преимущественно печатных красок. Сущность изобретения: полиол модифицируют растительным маслом или его жирной кислотой, продукт модификации подвергают взаимодействию с дикарбоновой кислотой или ее ангидридом и эфиром канифоли с кислотным числом 120-150 мгКОН/г и температурой плавления 130-145°C при расходе последнего 5-30% от массы карбоксилсодержащего олигоэфира полиола. Последний обрабатывают ди- или полиизоцианатом в среде органического растворителя.Field of use: production of coatings for paper, mainly printing inks. The inventive polyol is modified with vegetable oil or its fatty acid, the modification product is reacted with dicarboxylic acid or its anhydride and rosin ester with an acid number of 120-150 mgKOH / g and a melting point of 130-145 ° C at a flow rate of 5-1-30% of the latter mass of carboxyl-containing oligoester of the polyol. The latter is treated with di- or polyisocyanate in an organic solvent.
