摘要 PROBLEM TO BE SOLVED: To obtain the subject new compound having a sufficient hardening performance with a small amount compared to conventional similar compounds and related resol resins, therefore useful as e.g. the main agent for coating materials, molding material, adhesive, binder, additive for photosensitive printing plates. SOLUTION: This new compound is a hydroxymethyl group-contg. phenolic compound of formula I (R is CH2OH or H; wherein at least two of Rs are each CH2OH), e.g. a compound wherein all of Rs are CH2OH each in formula I. The compound of formula I is obtained, for example, by the following process: 15 g of a phenolic compound of formula II is dissolved in a mixed solution of 35 mL of an aqueous NaOH solution (15%) and 25 mL of methanol to form a reaction liquid, into which 33 g of formalin (37%) is dripped at room temperature under agitation; the resulting liquid is heated to 40 deg.C and then agitated for 20 h and subsequently put into an aqueous acetic acid solution, and the resulting viscous oily product is separated by decantation from the resulting aqueous layer and washed with water and then dried under reduced pressures.
