Claims
- 1. A method of wet-laminating a film or foil substrate and a construction substrate comprising(a) forming a one-part aqueous, organic solvent-free laminating adhesive composition comprising an adhesive copolymer consisting essentially of a vinyl ester/acrylic copolymer comprising from about 0.1% to about 20%, by weight based on copolymer weight, of a copolymerized ethylenically unsaturated carboxylic acid monomer, wherein said copolymerized carboxylic acid is neutralized to the extent of from 5% to 100%, on an equivalents basis, with a nonvolatile base, said copolymer having a glass transition temperature from about 10 C. to about −35 C. (b) applying said composition to a first substrate; (c) contacting said composition with a second substrate; and (d) drying said composition.
- 2. The method of claim 1 wherein said glass transition temperature is from about −5 C. to about −25 C..
- 3. The method of claim 1 wherein said copolymer comprises a stabilizer selected from the group consisting of hydroxyethyl cellulose and polyvinyl alcohol.
- 4. The method of claim 1 wherein said copolymer comprises from about 0.2% to about 10%, by weight based on copolymer weight, of said copolymerized polar monomer.
- 5. The method of claim 1 wherein said copolymer comprises a copolymerized acrylic monomer selected from the group consisting of n-butyl acrylate and 2-ethylhexyl acrylate.
- 6. The method of claim 1 wherein said vinyl ester/acrylic copolymer is a vinyl acetate/butyl acrylate/2-ethylhexyl acrylate/acrylic acid copolymer comprising from about 0.1% to about 20%, by weight based on said copolymer weight, of acrylic acid, said copolymer having a glass transition temperature from about 10 C. to about −35 C.
- 7. A laminate prepared by the method of claim 1.
