<p>PURPOSE:To form an extremely strong adhesive structure and to improve remarkably processability and corrosion resistance accompanied therewith by distributing a surface treating agent-interlocating adhesive structure and surface treating agent-unexisting adhesive structure on the adhesive face between a metal sheet and a thermoplastic resin film. CONSTITUTION:A org. surface treating agent is provided on the surface of a metal sheet so as to make an effective coating area ratio to be 98% or less, especially 1-95%. In addition, the surface roughness of the metal sheet after coating with the surface treating agent is made to be 0.01-5 mum, especially 0.02-2mum. The surface treating agent- coated metal sheet 1 consists of a metal sheet 2 and a surface treating agent layer 3 provided on at least one surface thereof but this surface treating agent layer 3 is not continuous and always has an exposed face of the metal sheet of a covered face 4 thereof. On the adhesive face between the metal sheet 2 and the thermoplastic resin film 5, a part 6 of adhesive structure consisting of the metal sheet 2 the surface treating agent 3 and the thermoplastic resin film 5 and a part 7 of adhesive structure consisting of the metal sheet 2 and the thermoplastic resin film 5 are mixed so as to form both adhesive distribution structure. The adhesive structure is remarkably increased thereby.</p> |
