METHOD OF COATING A STEEL WITH A THERMOPLASTIC RESIN (COMPOSITION) AND A LAMINATED ARTICLE OBTAINED BY SAID METHOD

摘要

A method of coating a steel with an ethylene-.alpha.-olefin copolymer resin which is characterized by using said ethylene-.alpha.-olefin copolymer resin (A) having a density of 0.915 to 0.927 g/cm3, a melt flow rate (MFR2.16) determined at 190.degree.C under a load of 2.16 kg of 0.1 to 1.0 g/10 min., a melt flow rate ratio (MFRR) defined by the following formula (1) of 30 or more, and the product of MFR2.16 and MFRR of 8 to 45. MFRR= MFR21.6 / MFR2.16 (1); MFR21.6 : A melt flow rate determined at 190.degree.C under a load of 21.6 kg; MFR2.16 : A melt flow rate determined at 190.degree.C under a load of 2.16 kg. A method of coating a steel with a thermoplastic resin composition which is characterized by using said thermoplastic resin composition comprising not less than 75 % by weight and less than 100 % by weight of a component (A) and not more than 25 % by weight of a component (B). Component (A) : the above-mentioned ethylene-.alpha.-olefin copolymer resin (A). Component (B) : at least one component selected from the group consisting of the following components (B-1), (B-2) and (B-3). Component (B-1) : a high-pressure low density polyethylene having a melt flow rate determined at 190.degree.C under a load of 2.16 kg of 0.2 to 100 g/10 min. Component (B-2) : an ethylene-unsaturated carboxylic acid ester copolymer resin containing 0.1 to 10 % by weight of an unsaturated carboxylic acid ester and having a melt flow rate determined at 190.degree.C under a load of 2.16 kg of 0.2 to 100 g/10 min. Component (B-3) : an ethylene-vinyl ester copolymer resin containing 0.1 to 10 % by weight of a vinyl ester and having a melt flow rate determined at 190.degree.C under a load of 2.16 kg of 0.2 to 100 g/10 min. Laminated articles obtained by said methods.
