Abstract
This invention relates to a novel phosphorus-containing phenol novolac resin, use of the phosphorus-containing phenol novolac resin as a halogen-free flame retardant epoxy hardener, and an epoxy resin composition having high phosphorus content because it includes the phosphorus-containing phenol novolac resin, thereby exhibiting superior flame retardancy and heat resistance.
