Abstract:
A phenol resin obtained by reacting at least two components, i.e., a compound (A) represented by the following general formula (I) and a polymerizable phenol compound represented by the following general formula (II) or a polymer (B), which is a polymer of the polymerizable phenol compound, in a ratio of 1 to 50 moles of the compound (A) to 100 moles of the polymerizable phenol compound or 100 moles of a structural unit of the polymerizable phenol compound contained in the polymer (B) in the presence of an acid and having a weight average molecular weight of 2,000 to 20,000 ##STR9##(wherein R.sup.1, R.sup.2, R.sup.3, and R.sup.4, which are the same or different, independently represent a hydrogen atom, an alkyl group, an alkoxy group, an aryl group, an aralkyl group, a hydroxyl group or a halogen atom) ##STR10##(wherein R.sup.5 represents a hydrogen atom or a methyl group, R.sup.6, R.sup.7, R.sup.8, and R.sup.9, which are the same or different, independently represent a hydrogen atom, an alkyl group, an alkoxy group, an aryl group, an aralkyl group, a hydroxyl group or a halogen atom, provided that at least one of R.sup.7 and R.sup.9 is a hydrogen atom).
