Abstract
A novel resin composition which is composed of molecules having an epi-bis type main skeleton of the formula ##STR1## X.sub.1 -X.sub.4 : H, Cl or Br R: H, or CH.sub.3 and has a Gardner-Holdt viscosity of C to Z.sub.8 determined at 25.degree. C. for a solution in butyl carbitol in a concentration of 40% by weight. At least 40% of the entire terminal groups of the molecules of the novel composition consists of .alpha.-glycol groups of the formula ##STR2## wherein R represents hydrogen or methyl. The composition is more rapidly curable at lower temperatures than known epoxy resins having an epi-bis type main chain skeleton, and is useful as a paint or adhesive and also as an adhesion improver for other resins.
