Zusammenfassung:	A PHOTOIMAGABLE SOLDER MASK COATING A UV sensitive coating composition is described which is a polymer prepared from a condensation reaction of a diisocyanate, a hydroxy alkyl (di or tri) (meth)acrylate and a carboxylic acid polyol. Optionally, a polyol and/or a dicarboxylic acid polyol can also be included as reactants. The coating polymer, thus prepared, can also be combined with binders and crosslinkers.
