PROBLEM TO BE SOLVED: To obtain a new compound useful as a raw material or an additive of a resist for the fine processing of a semiconductor. SOLUTION: The objective compound is expressed by the formula (one of R<1> to R<5> is OH, one of R<6> to R<10> is OH and the remaining R<1> to R<10> are each H, a 1-6C alkyl or OH), e.g. 4,4'-methylenebis[2- 2-hydroxy-3-(2-hydroxybenzyl)-5- methylbenzyl}-3,6-dimethylphenol]. The compound can be produced by reacting 4,4'-methylenebis[2-(2-hydroxy-3-hydroxymethyl-5-methylbenzyl)-3,6- dimethylphenol] with a phenolic compound at a molar ratio of 1:(2-50) in the presence of an acidic catalyst. |
