| 20110045288 | EASY-ADHESIVE FILM - The present invention relates to a polyester film having an excellent easy-adhesive property to a topcoat agent which can be suitably used in the applications in which a good adhesion to the topcoat agent is required. There is provided an easy-adhesive film comprising a polyester film and a coating layer formed on the polyester film by a coating/stretching method, wherein the coating layer comprises a polyurethane resin having a polycarbonate structure and a carboxyl group and exhibiting a glass transition point of not higher than 10° C., and further comprises not more than 20% by weight of a crosslinking agent having a heat-crosslinkable functional group in an amount of not less than 10 mmol/g. | 02-24-2011 |
| 20110045291 | EASY-ADHESIVE POLYESTER FILM - The present invention provides a polyester film which is excellent in easy-adhesive property to a topcoat agent, in particular, excellent in adhesion between a coating layer, a topcoat layer and a polyester base film even when the topcoat layer is formed of a solvent-free active energy radiation-curing resin. The present invention relates to an easy-adhesive polyester film comprising a polyester film and a coating layer formed on one surface of the polyester film which is obtained by applying a coating solution comprising a vinyl group-containing polyurethane resin thereonto. | 02-24-2011 |
| 20110051245 | OPTICAL LAMINATED POLYESTER FILM - The present invention provides an optical laminated polyester film which can exhibit a good adhesion to a light diffusion plate, a prism layer and a hard coat layer as well as an excellent antistatic property without deterioration in transparency. The present invention relates to an optical biaxially oriented polyester film comprising a polyester film, a coating layer comprising a cationic polymer which is formed on one surface of the polyester film, and a layer formed on the other surface of the polyester film which is obtained by applying thereonto a coating agent comprising a polyurethane comprising a diol component having a polycarbonate structure, and a heat-crosslinking agent. | 03-03-2011 |
| 20110054090 | POLYESTER FILM - An object of the present invention is to provide a polyester film which is reduced in yellow discoloration, has a high quality and can be suitably used for optical filters (for example AR films, NIR films and EMI films), films for liquid crystal applications (for example diffraction films and prism films), materials for electric appliance, films for packaging, materials for graphic appliance (photograph materials), plate making films, OHP films or the like. | 03-03-2011 |
| 20110070400 | RELEASE FILM - The present invention provides a release film comprising a polyester film which is capable of realizing a high-accuracy inspection of a polarizing plate without undergoing any of problems such as difficulty in detection of foreign matters or defects and likelihood of overlooking thereof when inspecting the polarizing plate by a Cross-Nicol method. The present invention relates to (i) a release film for a polarizing plate which comprises a polyester film and a release layer formed on one surface of the polyester film by a coating/stretching method, wherein a haze of the release film is 7 to 18%, and an L value of the release film is not more than 77 as measured form a side of the release layer by a reflection method; and (ii) a release film for a polarizing plate, comprising a polyester film and a release layer formed on one surface of the polyester film by a coating stretching method, wherein a surface roughness (Ra) of the release film is 11 to 25 nm, and an image clarity value of the release film is not less than 90%. | 03-24-2011 |
