Epoxide resin-modified polyesters derived from carboxyl polyol |
摘要 |
A water-dilutable coating comprising a binder obtained from an epoxide resin-modified polyester possessing free carboxyl groups prepared from the reaction of: A) a polyester polymerized from: a1) a polycarboxylic acid containing at least three carboxyl groups and/or a2) a polyol containing at least one carboxyl group and a3) a polycarboxylic acid containing two carboxyl groups and a4) a polyol; wherein the polyester contains (cyclo)aliphatic elements having at least six carbon atoms; and B) from 0.3-1.5 equivalents per polyester molecule of a bisphenol epoxide resin or a reaction product thereof containing at least one epoxide group per molecule with a carboxylic acid.
