Process for the preparation of polyesters or alkyd resins, resins which may be obtained according to this process and the use thereof as lacquer binders

摘要

Penta- or hexahydric sugar alcohols are outstandingly suitable as a polyol component for the preparation of polyesters or alkyd resins. Secondary reactions resulting in darkening are substantially avoided if as small a quantity as possible of aromatic polycarboxylic acid components is used.
