Abstract
Abstract A laminated member comprising a metal foil or sheet (1) and a thermoplastic resin film (4) bonded together with an adhesive selected from a carboxyl group-containing polyolefin and a polyolefin based resin prepared by heat-compounding a carboxyl group-containing polyolefin and a metal compound, is heated at a higher temperature than the melting temperature of the adhesive and pressed using a heated roll (3) and a nip roll (6). The laminated member is then cooled at the heat distortion of the adhesive or at a temperature somewhat higher than the heat distortion temperature while applying a pressure of at least 0.2 Kg/cm<2> with a cooling roll (10) and a nip roll (11).

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
131 words
A process for producing a laminated member including a metal foil or sheet (1) and a thermoplastic resin film (4), said process comprising the steps of heating thefoil or sheet (1) and the film (4) with at least one adhesive disposed therebetween, said adhesive being selected from a carboxyl group-containing polyolefin and a polyolefin based resin prepared by heat-compounding a carboxyl group-containing polyolefin and a metal compound, at a temperature which is higher than the melting temperature of the adhesive and pressing to form a laminated member (8); and cooling the laminated member (8) when at the heat distortion temperature of the adhesive or at a temperature higher than the heat distortion temperature while applying a pressure at least 0.2 Kg/cm using a cooling roll (10) and a nip roll (11).
Claim 2
Dependent Claim
131 words
A process for producing a laminated member including a metal foil or sheet (1) and a thermoplastic resin film (4), said process comprising the steps of heating thefoil or sheet (1) and the film (4) with at least one adhesive disposed therebetween, said adhesive being selected from a carboxyl group-containing polyolefin and a polyolefin based resin prepared by heat-compounding a carboxyl group-containing polyolefin and a metal compound, at a temperature which is higher than the melting temperature of the adhesive and pressing to form a laminated member (8); and cooling the laminated member (8) when at the heat distortion temperature of the adhesive or at a temperature higher than the heat distortion temperature while applying a pressure at least 0.2 Kg/cm using a cooling roll (10) and a nip roll (11).
Claim 3
Dependent Claim
25 words
The process as claimed in Claim 1, wherein the adhesive is a graft polymer of polyolefin and an α, β - ethylenically unsaturated carboxylic acid.
Claim 4
Dependent Claim
37 words
The process as claimed in Claim 1 wherein the adhesive is a polyolefin based resin prepared by heat -compounding a graft polymer of polyolefin and an α, β - ethylenically unsaturated carboxylic acid, and a metal compound.
Claim 5
Dependent Claim
33 words
The process as claimed in Claim 3, wherein the polyolefin based resin is prepared from 100 parts weight of the carboxyl group-containing polyolefa-and 0.05 to 10 parts by weight of the metal compound.
Claim 6
Dependent Claim

Claim 7
Dependent Claim
40 words
The process as claimed in Claim 1, 2, 3, 4 or 5, wherein the heating and pressing step is carried out by bringing the metal foil or sheet (1) of the laminated member in contact with a heated roll (3).
Claim 8
Dependent Claim
37 words
The process as claimed in Claim 1, 2, 3, 4, 5 or 6, wherein the adhesive is extruded as a molten film and sandwiched between the metal foil or sheet (1) and the thermoplastic resin film (4).
Claim 9
Dependent Claim
27 words
The process as claimed in Claim 1, 2, 3, 4, 5, 6 or 7,wherein the thermoplastic resin film (4) is a polyolefin film or a nylon film.
Claim 10
Dependent Claim
27 words

Claim 12
Dependent Claim
14 words
A laminated member when produced by the process as claimed in any preceding claim.
