    Abstract: A naphthol-modified phenolic resin having low softening point and good flowability is obtained by allowing a naphthol and a phenol to react with an aldehyde in the presence of an acid catalyst at 60 to 110.degree. C. to obtain a primary reaction mixture, heating the primary reaction mixture in the presence of a strong acid, a super acid or a mixture thereof under ambient pressure at 120 to 180.degree. C. for 1 to 12 hours to obtain a secondary reaction mixture, and subjecting the secondary reaction mixture to vacuum concentration or steam distillation, and the naphthol-modified phenolic resin is suited to use as a curing agent in epoxy resin molding materials for sealing electronic parts.

    Abstract: The present invention provides a phenol resin having, as a unit in its main-chain skeleton, a structure represented by the following general formula (I), as well as a resin composition using the same. According to the phenol resin of the invention, epoxylation thereof, chemical modification thereof, reaction thereof with an epoxy resin, and the like are facilitated. Phenol resins ranging from low-molecular-weight resins rich in fluidity to high-melting resins can be synthesized, and these phenol resins are industrially useful. When the phenol resin of the present invention is used as a hardening agent for epoxy resin etc., its resin composition can give a cured product of high Tg without deteriorating adhesiveness.
