Title:
OPTICAL LAMINATE
Document Type and Number:
WIPO Patent Application WO/2021/261119
Kind Code:
A1
Abstract:
This optical laminate 1 comprises a glass plate 2, an adhesive layer 3, a film 4, and a pressure-sensitive adhesive layer 12 in the stated order toward one side in the thickness direction. The glass plate 2 has a thickness of 40-60 μm (inclusive). The average tanδ of the film 4 at a temperature from -100°C to -50°C is 0.06 or higher, said average being derived through a dynamic viscoelasticity test in a tension mode and at a frequency of 10 Hz and a warming rate of 2°C/min. The average tensile elastic modulus E' of the film at a temperature from -100°C to -50°C is 3-6 GPa (inclusive), said average being derived through the dynamic viscoelasticity test. The pressure-sensitive adhesive layer 12 has a thickness of 20 μm or less.
