Document Type and Number:
WIPO Patent Application WO/2018/199686
Kind Code:
A1
Abstract:
The present invention provides: an optical transparent adhesive sheet comprising a (meth)acrylate syrup, a photo-initiator, and a (meth)acrylate monomer, wherein in the optical transparent adhesive sheet, the storage modulus after primary UV crosslinking is 1.0 × 106 to 1.0 × 107 Pa at 25°C and 1 Hz and 5.0 × 104 to 5.0 × 105 Pa at 70°C and 1 Hz, and the rate of increase in storage modulus at 25°C after curing after secondary UV crosslinking is 10-100% compared with the storage modulus at 25°C after primary UV crosslinking; a composition for preparing the optical transparent adhesive sheet; and a flat display device using the optical transparent adhesive sheet.
