PROBLEM TO BE SOLVED: To provide a resin composition good in adhesion property including heat shock durability of a cold and warm bath cycle including water at injection molding without requiring pre-molding treatment such as primer coating to a metal such as a steel plate or a stainless.SOLUTION: A resin composition for coating a metal contains (A) a polyester elastomer obtained by copolymerizing polyether diol having a number average molecular weight of 500 to 4,000 and having a content of the polyether diol of 50 to 65 mass%, (B) a low crystallinity resin, (C) a polyolefin elastomer, (D) an epoxy compound and (E) a tackifier, with mass ratios of [(A)+(B)]/(C)/(D)/(E)=[100]/(20-50)/(10-30)/(10-30) and (A)/(B)=(92-80)/(8-20). |
