An epoxy resin composition for moving the remaining trace of an old building such as cultural properties is provided to improve storage stability for a long time and releasability. An epoxy resin composition comprises 100 wt% of a base which comprises 5-15 wt% of lauryl glycidyl ether, 1-5 wt% of 3-glycidoxypropyltrimethoxysilane, 5-10 wt% of trimethylolpropane polyglycidyl ether, 1-10 wt% of butadiene-acrylonitrile copolymer, 0.05-1 wt% of epichlorohydrin, and the balance of diglycidyl ether of bisphenol F; and 40-60 wt% of a curing agent which comprises 5-20 wt% of 1,4-bis(amino(cyclohexyl)methane), 2-10 wt% of 3,3-(oxybis-2,4-ethane-diyloxy)bis-1-propanamine, 5-10 wt% of a C18 unsaturated fatty acid dimer, 5-10 wt% of poly(oxy(methyl-1,2-ethanediyl)), 7-10 wt% of alpha-2-(2-aminomethylethyl)-Ћ-(2-aminomethylethoxy), 5-10 wt% of nonyl phenol, 10-15 wt% of 2,4,6-tri(dimethylamino)methyl phenol, and the balance of triethylene tetramine.
