  A phenolic resin composition in which the phenolic resin can be smoothly cured at a low temperature while inhibiting the generation of free formaldehyde and trapping free phenol. An epoxy compound is dispersed or dissolved as a hardener in an aqueous phenolic resin solution. The epoxy compound functions not only as a hardener for the phenolic resin but as a trapping agent for free phenol. The phenolic resin has been sulfoalkylated and/or sulfialkylated so as to have improved hydrophilicity.
