Description

The invention relates to printing industry, in particular printing ink for offset or letterpress printing on paper.

The purpose of the invention is to increase the stability of paint and gloss print,

Alkyd-amine resin used in this invention, get in 3 stages:

a) alcoholysis of sunflower oil with pentaerythritol at a temperature of 255-280 C and the esterification of the resulting product with isophthalic acid at the same temperature and an 8: 1: 2 ratio (w / w) to an acid number of 8-14 mg KOH / g;

b) amination of the obtained alkyd polyether from 6 to 12% by weight of polyethylene-polyamines (80-90% of triethyltertetramine and 10-20% of diethylenetriamine) at 110-130 ° C and the formation of a gelled (non-flowing) mass with an amine number of 80 -110 and free amine content not more than 2% and acid number not more than 4 mg KOH / g;

c) diluting the alkyd-aminine resin with an olefin fraction at 50-80 ° C from T., n 265-310 ° C to a working one in h. (250-350 P at).
