WIPO Patent Application WO/2014/175463
Kind Code:
A1
Abstract:
Provided is an optical laminate in which a transparent front plate (COV), an ultraviolet curable adhesive layer (ADH), a polarizing plate (POL2), a pressure-sensitive adhesive layer (not shown) and a transparent substrate (SUB2) are arranged in this order. The ultraviolet curable adhesive layer (ADH) is formed of an ultraviolet curable adhesive composition that contains an acrylic acid ester monomer having 6-11 carbon atoms in an ester moiety. The pressure-sensitive adhesive layer has a creep amount within the range of 90-1,000 μm after 3,000 seconds when the pressure-sensitive adhesive layer having an area of 25 mm × 25 mm is bonded to an alkali-free glass substrate and a load of 3 kg is applied thereto at 23°C at a relative humidity of 55%.
