Title:
ADHESIVE SHEET
Document Type and Number:
WIPO Patent Application WO/2010/067745
Kind Code:
A1
Abstract:
Disclosed is an adhesive sheet comprising a substrate and an adhesive layer formed from an adhesive composition containing a polyrotaxane (A) for which a linear molecule penetrates the aperture parts of at least two cyclic molecules, one or more reactive groups exist in the aforementioned cyclic molecules, and a blocking group exists at both terminals of the aforementioned linear molecule. The rupture elongation of the aforementioned adhesive layer is 300% or higher, the haze value is 30% or less, and the retention strength of the aforementioned adhesive sheet measured in accordance with JIS Z0237—except that the measurement temperature is 80°C—is 1000 μm or less as the displacement of the aforementioned adhesive sheet after 70,000 seconds. When applied to an optical member such as a polarizing plate or a retardation plate, due to said adhesive sheet and the adhesive layer thereof the stress-relaxation property and thus the ability to prevent optical leakage are excellent, and the durability is excellent, while optical characteristics such as the total light transmittance are sufficiently achieved.
