PURPOSE:To provide the title compsn. having excellent corrosion resistance, processability and moldability and suitable for use in coating containers for beverage and food, containing a specified modified bisphenol epoxy resin and a phenolic resin and/or amino resin. CONSTITUTION:An ester having epoxy groups and a number-average MW of 2,900-3,800, obtd. by esterifying a bisphenol epoxy resin (a) having an epoxy equivalent of 1,700-3,500 and a number-average MW of 2,900-3,800 or a bisphenol epoxy resin (b) having an epoxy equivalent of 180-1,500 with a satd. dibasic acid, is reacted with bisphenol (c) in a ratio of 1mol of epoxy group of the component (a) or (b) to 1-2mol of phenolic hydroxyl group of the component (c) at 130-200 deg.C to obtain a modified bisphenol epoxy resin (A wherein at least one functional group of the formula (wherein R is a 1-4C bivalent aliph. hydrocarbon group) is introduced into the molecular terminal of the component (a) or (b). 50-95pts.wt. component A is blended with 50-5pts.wt. phenolic resin and/or amino resin (B).
