Title:
ADHESIVE LAMINATE HAVING WATER VAPOR BARRIER PROPERTIES AND IMAGE DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/006352
Kind Code:
A1
Abstract:
An adhesive laminate having water vapor barrier properties and including a base material and an adhesive layer provided upon the base material. The adhesive layer is obtained from an adhesive composition including a hydrogenated block copolymer (A), a first compatibilizing agent (B), and a second compatibilizing agent (C).The hydrogenated block copolymer (A) has a hard segment derived from a polymer component of an aromatic vinyl monomer and a soft segment derived from a polymer component of a conjugated diene monomer. The first compatibilizing agent (B) is compatible with the hard segment and has a softening point of at least 80°C. The second compatibilizing agent (C) is compatible with the soft segment and is liquid at normal temperature (23°C). The film thickness of the adhesive layer is 5-300 µm and the water vapor transmission when the film thickness of the adhesive layer is 50 µm is less than 100 g/m2·day at 40°C × 90% RH under JIS Z0208.
