Abstract:
A one-packed epoxy resin composition comprising:(A) an epoxy resin having two or more epoxy groups in the resin molecule and said epoxy resin having a number average molecular weight of 250 to 4,500,(B) a ketimine compound,(C) a dehydrating agent, and(D) at least one epoxy resin (d-1) selected among urethane-modified epoxy resins prepared by reacting a polyisocyanate or monoisocyanate compound with an amine-added epoxy resin; amine-modified epoxy resins obtained by addition-polymerizing an epoxy resin with a polyvalent phenol such as bisphenol A to obtain an epoxy resin having a desired molecular weight and then reacting the obtained resin with an alkanol amine; and dimer acid-modified epoxy resins obtained by addition-polymerizing a polyvalent phenol such as bisphenol A and an adduct of an epoxy resin with a dimer acid; and/or a resin (d-2) which has a softening point of 60.degree. C. or above and is at least one member selected among xylene resins obtained by reacting meta-xylene with formaldehyde using a catalyst such as sulfuric acid and further reacting the obtained xylene resin with a phenol or a rosin; ketone resins obtained by reacting a ketone such as cyclohexanone with a formaldehyde using a catalyst such as sulfuric acid; coumarone resins obtained by refining a 160 to 180.degree. C. distillate fraction of naphtha and polymerizing the refined product by heating or with sulfuric acid; and petroleum resins obtained by cationically polymerizing, with a Friedel-Crafts catalyst, C.sub.5 or higher olefin residues from oil cracking.
