Document Type and Number:
WIPO Patent Application WO/2015/099022
Kind Code:
A1
Abstract:
This laminated polarizing film comprises a polarizing film and a non-polarizer optical film laminated together with a low-modulus-adhesive layer (a) interposed therebetween. The polarizing film comprises a polarizer, at least one surface of which has a transparent protective film laminated thereto with an adhesive layer (b) interposed therebetween, and the aforementioned low-modulus-adhesive layer (a) is laminated to (one of) said transparent protective film(s). The low-modulus-adhesive layer (a) is between 0.1 and 5 µm thick, inclusive, and at 25°C, exhibits a storage elastic modulus between 3.0×105 and 1.0×108 Pa, inclusive. This laminated polarizing film exhibits good impact resistance and heat-buckling characteristics.
