- 20 - ABSTRACT The present invention relates to an under-coating composition which comprises 100 weight part of chlorinated polyolefin resin including 15 to 35 wt. % of chloride and 1 to 70 weight part of epoxy resin having an equivalent epoxy of 50 to 600 in order to be capable of eliminating the pretreatment of a surface to be overcoated of polyolefin resin substrate and improving the adhesion strength between the over-coatings and the surface of the substrate of polyolefin resin. Especially, the coating surface according to the present invention is much improved in a resistance to hot water and a resistance to humidity. Further, an use of the under-coating composition according to the present invention permits an over-coating film to have a high resistance to the water decoloration.
