摘要
The present invention provides a flame retardant phenol resin material which includes a phenol condensate, wherein a poly-aromatic compound obtained by a reaction of phenols (A) to aromatics (B) except for phenols and a heterocyclic compound (C) including nitrogen as heteroatom are condensed via aldehydes (D), and also provides a flame retardant epoxy resin material which includes an epoxy resin obtained by glycidyl-etherification of at least a part of phenolic hydroxyl groups of a poly-aromatic compound obtained by a reaction of phenols (A) to aromatics (B) except for phenols and a heterocyclic compound (C) including nitrogen as heteroatom are condensed via aldehydes (D).
