Beschreibung
Zusammenfassung:	The present invention provides for amino-crosslinkable coating formulations based on a mixture of a di or polyhydroxy functional polymeric component selected from the group consisting of diesters, polyesters, alkyd polymers, acrylic polymers and polycarbonate polymers, a methylol (alkoxymethyl) amino crosslinking agent and a bis-aromatic polyhydric phenol component having the structure of formula (I), wherein X is selected from the group consisting of carbon to carbon covalent bond, oxygen, sulfur, -S-S-, -CO-, -SO-, -SO2- and a divalent organic radical having a molecular weight less than about 400, and wherein Y is independently selected from the group consisting of hydrogen, halogen, C1 to C4 alkyl and C1 to C4 alkoxy. The crosslinkable compositions of this invention may be used to prepare curable coating and paint formulations, and also may contain other ingredients such as a crosslinking catalyst, fillers, pigments and the like.
