Abstract
Abstract A curable composition comprising (a) a resin containing free hydroxyl groups which is obtained by the reaction of a compound of formula R'(CH.sub. 2 X) a , wherein R' is a divalent or trivalent aromatic hydrocarbon or a di(aromatic hydrocarbon) ether, X is an alkoxy group of 1 to 6 carbon atoms or is chlorine, bromine or iodine and a is 2 or 3, with a phenolic compound, (b) a cycloaliphatic epoxy compound containing at least two 1,2 - epoxide groups per molecule and (c) an amino compound selected from the group consisting of imidazoles, N-substituted imidazoles, triethylene diamine, and benzimidazoles.
