Patent ID: 7220337

Claim:
A method of large-surface-area adhesive bonding of a UV-transparent film substrate to second substrate, which comprises: applying a laminating adhesive comprising: an aqueous polymer dispersion, wherein a) the laminating adhesive comprises from 0.0001 to 0.5 mol of a photoinitiator which on exposure to high-energy light causes a crosslinking reaction; and b) the polymer dispersed in the dispersion has from 0.0001 to 1 mol of keto or aldehyde groups, the molar data being based in each case on 100 g of the dispersed polymer to at least one of the substrates to form an adhesive film; drying the adhesive film; adhesively bonding the substrates; and then exposing the UV-transparent film to high-energy light, wherein the second substrate comprises paper or card.
