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 heating roll (3) and a nip roll (6). The laminated member is then cooled at the heat distortion temperature of the adhesive or at a temperature 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: 11
Claim 1
Independent Claim
155 words
A process for producing a laminated member including a metal foil or a metal foil backed with a thermoplastic resin (1) and a thermoplastic resin film (4) said process comprising steps of: heating the foil (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) at the heat distortion temperature of the adhesive or at a temperature higher than the heat distortion temperature while applying a pressure of at least 1 kg/cm 2 using a cooling roll (10) and a resilient nip roll (11) such that said laminated member (8) is brought into contact first with the resilient nip roll (11).
Claim 2
Dependent Claim
155 words
A process for producing a laminated member including a metal foil or a metal foil backed with a thermoplastic resin (1) and a thermoplastic resin film (4) said process comprising steps of: heating the foil (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) at the heat distortion temperature of the adhesive or at a temperature higher than the heat distortion temperature while applying a pressure of at least 1 kg/cm 2 using a cooling roll (10) and a resilient nip roll (11) such that said laminated member (8) is brought into contact first with the resilient nip roll (11).
Claim 3
Dependent Claim
22 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
33 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
35 words
The process as claimed in claim 3, wherein the polyolefin based resin is prepared from 100 parts by weight of the carboxyl group-containing polyolefin and 0.05 to 10 parts by weight of the metal compound.
Claim 6
Dependent Claim
26 words
The process as claimed in claim 4, wherein the polyolefin based resin is prepared from a graft polymer of polypropylene and maleic acid, and aluminum hydroxide.
Claim 7
Dependent Claim
43 words
The process as claimed in claim 1, 2, 3, 4 or 5, wherein the heating and pressing at the first 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
36 words
The process as claimed in claim 1, 2, 3, 4, or 5, 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
26 words
The process as claimed in claim 1, 2, 3, 4, or 5, wherein the thermoplastic resin film (4) is a polyolefin film or a nylon film.
Claim 10
Dependent Claim
23 words
The process as claimed in claim 1, 2, 3, 4, or 5, wherein the metal foil (1) is backed with a heat-resistant resin.
Claim 11
Dependent Claim
28 words
The process as claimed in claim 1, 2, 3, 4 or 5, wherein the second step is carried out at the softening point of the adhesive or more.
