<P>PROBLEM TO BE SOLVED: To provide a phenol derivatization type compound useful for epoxy resin curing agents, a method for producing the same, an epoxy resin curing agent which has high compatibility with an epoxy resin composition and gives an epoxy resin cured product having a high glass transition temperature, and an epoxy resin composition containing the curing agent and an epoxy resin. Ž<P>SOLUTION: The phenol derivatization type compound is a phenolic compound of formula (1) [wherein Ar<SP>1</SP>and Ar<SP>2</SP>are each a phenylene group of formula (2) or a naphthalene group of formula (3); X is a direct bond, a divalent hydrocarbon group which may contain an atom of a different kind, O, S or SO<SB>2</SB>; R<SP>1</SP>to R<SP>3</SP>are each a 1-15C hydrocarbon group or a hydroxy group; v, w, and x are each 0-3; and n is not less than 0] having two or more hydroxy groups which are substituted with a substituent of formula (4) (wherein R<SP>4</SP>is a 1-15C hydrocarbon group) at a substitution rate of 10 to less than 100%. The method for producing the same, the epoxy resin curing agent composed of the same, and the epoxy resin composition including the curing agent are provided. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
