Abstract
Flyback transformers having good adhesiveness, crack resistance, arc resistance, without producing corona discharge can be produced by insulation treating flyback transformers with a low-shrinkage resin composition comprising (a) an unsaturated polyester produced by reacting partially esterified dicyclopentadiene carboxylic acid, which has been obtained by reacting dicyclopentadiene or hydroxylated dicyclopentadiene, and maleic acid or anhydride, with one or more polyhydric alcohols, (b) a monomer having a vinyl group and (c) a low-shrinkage agent.
