Abstract:
(EN) 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.
(FR) La présente invention concerne : une feuille adhésive transparente optique comprenant un sirop (méth)acrylate, un photo-initiateur et un monomère (méth)acrylate, où dans la feuille adhésive transparente optique, le module de stockage après réticulation UV primaire est de 1,0 × 106 à 1,0 × 107 Pa à 25 °C et 1 Hz et de 5,0 × 104 à 5,0 ×105 Pa à 70 °C et 1 Hz, et le taux d'accroissement du module de stockage à 25 °C après durcissement, par réticulation UV secondaire est de 10 à 100 % comparativement au module de stockage à 25 °C après réticulation UV primaire ; une composition pour préparer la feuille adhésive transparente optique ; et un dispositif d'affichage plat utilisant ladite feuille adhésive transparente optique.
