Abstract
The invention relates to a polyester resin which is based on at least one fatty acid, with zero oil length (0%) or an oil length of between 0 and 35%, with a weight ratio of oxidizable fatty acids (monoacids), relative to the overall fatty acids, of 0 or greater than 0 and ranging up to 1, and which is based on an acid component comprising, in addition to the fatty acid, from 30% to 85% by weight, relative to the total weight of said resin, of rosin and/or of derivatives thereof bearing at least one carboxylic acid function.
