Phosphorus-containing phenolic resin, method for manufacturing the same, and use of the same
The present invention provides a novel phosphorus-containing phenolic resin. When the phosphorus-containing phenolic resin is used as an epoxy resin curing agent, the cured product thereof has various excellent properties such as excellent moisture resistance, low permittivity, a low dissipation factor, and excellent adhesion in addition to improved flame retardation. Specifically, the phosphorus-containing phenolic resin of the invention is represented by formula (1). The invention also provides a method for manufacturing the novel phosphorus-containing phenolic resin, a phenolic resin composition including the phosphorus-containing phenolic resin, an epoxy resin curing agent including the phenolic resin composition, an epoxy resin composition including the epoxy resin curing agent and an epoxy resin, a cured product obtained by curing the epoxy resin composition, and a copper-clad laminated plate obtained by using the epoxy resin composition as a matrix resin.
