ABSTRACT:
A urethane acrylate resin obtained by reacting a polyisocyanate with a polyester polyol having a molecular weight of 500 to 3,000, a low-molecular-weight polyol having a molecular weight of 60 to 400 and a hydroxyalkyl acrylate containing at least 70 mole % of a monohydroxyalkyl acrylate at an NCO/OH equivalent ratio in the range of 0.7 to 1.20.
The composition comprising the above urethane acrylate resin affords crosslinked products having extremely excellent, tough physical properties, and can therefore be advantageously employed, for example, for base coatings for paper and polyethylene films prior to vacuum metallizing, protective coatings after vacuum metallizing, covering materials for electromagnetic tapes and floppy discs, vehicles for printing ink, adhesives, etc.
