ABSTRACT:
An under-coating composition comprising 100 weight parts of chlorinated polyolefin resin including 15 to 35 wt. % of chloride and 1 to 70 weight parts of epoxy resin having an equivalent epoxy weight of less than or equal to 600 is capable of eliminating the pretreatment of a surface of polyolefin resin substrate which is to be overcoated 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 resistance to hot water and resistance to humidity. Further, the use of the under-coating composition according to the present invention permits an over-coating film to have a high resistance to water decoloration.
