RETARDATION FILM WITH PRESSURE-SENSITIVE ADHESIVE LAYER AND ELLIPTICAL POLARIZER AND LIQUID-CRYSTAL DISPLAY BOTH EMPLOYING THE SAME |
摘要 |
A retardation film with a pressure-sensitive adhesive layer is provided which has improved adhesion between a retardation film (20) comprising a polypropylene resin and the pressure-sensitive adhesive layer (40). The adhesive-layer-coated retardation film is constituted of a retardation film (20) comprising a polypropylene resin, a primer layer (30), and a pressure-sensitive adhesive layer (40) which have been formed in this order. The primer layer (30) comprises a modified polyolefin resin which has been modified with an unsaturated polycarboxylic acid or a derivative of an unsaturated polycarboxylic acid and with (meth)acrylic acid or a derivative of (meth)acrylic acid and has a weight-average molecular weight of 15,000-150,000. The retardation film (20) is made of a propylene/ethylene copolymer containing up to 10 wt.% ethylene units. It is preferable that the retardation film (20) of the adhesive-layer-coated retardation film be a quarter-wave plate. |
