| 主权项 | 1. A modified naphthalene formaldehyde resin obtained by reacting a deacetalized naphthalene formaldehyde resin and a compound represented by formula (2) in the presence of an acidic catalyst: wherein X and Y each independently represent a hydrogen atom, an alkyl group having 1 to 10 carbon atoms, an aryl group having 6 to 10 carbon atoms or a cyclohexyl group, a and b each represent an integer of 1 to 3, and n represents an integer of 0 to 2, the deacetalized naphthalene formaldehyde resin is obtained by subjecting a naphthalene formaldehyde resin to a deacetal treatment in the presence of water and an acidic catalyst, and the naphthalene formaldehyde resin is obtained by reacting a compound (A) represented by formula (1) and formaldehyde (B) in a molar ratio, (A):B), of 1:1 to 1:20 in the presence of an acidic catalyst, | ||
