Abstract
A water-insoluble condensation product of a polyalcohol, a dicarboxylic acid, from 5 to 35% by weight of a saturated monohydric alcohol having from 1 to 3 carbon atoms and, optionally, a monocarboxylic acid, said condensation product being soluble in lacquer solvents and useful for producing stoving lacquers.
Claims6
A water-insoluble product consisting essentially of the condensation product of an aliphatic or cycloaliphatic polyalcohol having 2 to 15 carbon atoms, an aromatic, cycloaliphatic or aliphatic dicarboxylic acid, from 0 to 40% by weight of a monocarboxylic acid and from 5 to 35% by weight of a saturated monohydric alcohol having from 1 to 3 carbon atoms, said condensation product having a molecular weight of between 500 and 2000, an acid number of 3 to 40 and an OH number of 40 to 300 and being soluble in lacquer solvents selected from the group consisting of hydrocarbons, alcohols, esters and ketones.
