ABSTRACT OF THE DISCLOSURE A method of coating a steel with a resin composition which is characterized by using said resin composition comprising: (A) 55 to 90% by weight of a high-pressure low density polyethylene which has a melt flow rate determined at 190°C under a load of 2.16 kg of 0.1 to 3.0 g/10 min. and a density of 0.915 g/cm3 or more and less than 0.930 g/cm3, and (B) 45 to 10% by weight of an ethylene-.alpha.-olefin copolymer which has a melt flow rate determined at 190°C under a load of 2.16 kg of 0.5 to 10.0 g/10 min., a density of 0.895 to 0.920 g/cm3, and has only one endothermic peak as determined with DSC, and the temperature of the top of said endothermic peak falls within the range of 70 to 115°C, and in which the endotherm in the temperature range of 70 to 115°C is 90% or more to the total endotherm, provides a laminated article comprising the steel and said resin composition having excellent corrosion resistance, abrasion resistance, chemical resistance and processability, and a laminated surface with a low stickiness and a high hardness, and a remarkably improved impact strength at low temperatures.
