Phenolic resin |
| abstract |
(57) [Problem] To provide a phenol resin which gives a good pattern shape, heat resistance, resolution and sensitivity in a resist for lithography and the like. SOLUTION: Compound (A) (4-hydroxymethyl- A phenolic resin obtained by reacting at least two components of a polymerizable phenol compound (e.g., parahydroxystyrene) or a polymer (B) which is a polymer of the polymerizable phenol compound; The compound (A) and the polymerizable phenol compound are used in an amount of 1 to 50 mol per 100 mol of the polymerizable phenol compound or 100 mol of the structural unit of the polymerizable phenol compound contained in the polymer (B). A phenol resin having a weight-average molecular weight of 2,000 to 20,000 obtained by reacting at least two components of the acidic phenol compound or the polymer (B) in the presence of an acid. |
