摘要:
The present invention relates to an acrylic pressure-sensitive adhesive composition which comprises a (meth)acrylic copolymer comprising 70 to 95 parts by weight of an alkyl(meth)acrylic acid ester monomer, in which alkyl has 2 to 14 carbon atoms, and 5 to 30 parts by weight of a (meth)acrylic acid ester monomer containing a copolymerizable aromatic group, wherein the composition has a gel fraction of 10 to 55% and a swelling ratio of 30 to 110, and a sol (uncross-linked polymer) eluted therein with a solvent has a weight average molecular weight of 600,000 or more; a polarizing plate comprising the composition; and a liquid crystal display device comprising the same. The composition according to the present invention provides workability such as an excellent durability and re-workability, and has an effect of improving a light leakage phenomenon, since the size of birefringence occurred under stress is very small.

摘要:
Disclosed is a system for providing a coupon service using receipts and a method for providing a coupon service using the same. More specifically, the invention relates to the system and the method that extract coupon information from the image of a receipt provided by a customer or a distribution store in order to accumulate points for a corresponding coupon given to the customer, wherein the consumer and the distribution store are respectively registered as a member and a member store of the coupon service provider. The system according to the invention comprises: a personal terminal of the consumer which includes an image acquisition unit for acquiring an image of the receipt; a coupon product manufacturer server which stores the coupon product information for a product to which a coupon is attached; a coupon service provider server that is connected to the personal terminal and the coupon product manufacturer server through the Internet and provides point information to consumers; a database server that is connected to the coupon service provider server and stores the coupon product information, the receipt image provided by the consumer, and the point information extracted from the receipt image; and an image analyzing and processing device that extracts the coupon information from the receipt information provided by the consumer in order to accumulate the points given to the corresponding consumer, wherein the points are calculated through the extracted coupon information.
