摘要:
An object of the present invention is to provide a resin-coated metal sheet which not only is excellent in stamping performance (lubricity of a resin layer) and film removability by alkaline cleaning but also has improved blocking resistance. Further, another object of the present invention is to provide a resin composition used for forming a resin layer having such properties on a metal sheet. A resin-coated metal sheet according to the present invention is characterized in that a resin layer containing polyethylene glycol whose number average molecular weight is 18,000 to 500,000 and paraffin wax whose average molecular weight is 400 or less is laminated on one side or both the sides of the metal sheet.
