<p><P>PROBLEM TO BE SOLVED: To provide a resin composition using a urethane decomposition product and more particularly an epoxy resin composition using a urethane decomposition product and having good properties. <P>SOLUTION: The epoxy resin composition comprises (a) a product (functional group equivalent: X) obtained by decomposing a urethane resin with an amine compound and (b) an epoxy resin (epoxy equivalent: Y), wherein the mixing ratio Z = [(x/X)/(y/Y)] is adjusted so that the ratio Z may fall in the range; 0.5 < = Z < = 2 [wherein x (g) and y (g) are the amounts of the resins used, respectively] in order for the composition to have stable curability better than that attained in different mixing ratios. <P>COPYRIGHT: (C)2004,JPO</p> |
