摘要:
The present invention provides a laminated polyester film which can be suitably used in the applications requiring a good visibility and a good adhesion property to a hard coat layer, etc., for example, such as various kinds of optical films as members of liquid crystal displays as well as molding films. The laminated polyester film of the present invention comprises a polyester film and a coating layer formed on at least one surface of the polyester film which is produced by applying a coating solution comprising a polyester resin having a naphthalene skeleton, a metal oxide and an aromatic isocyanate compound thereonto.
摘要:
The object of the present invention is to provide a release film in which the oligomer precipitation from the film surfaces constituting the release film in the respective film processing steps such as an adhesive-applying step of, drying step and sticking step is reduced as possible and it can be attained to improve the continuous production of film.The above object is attained by a release film comprising: a polyester film, coating layers which is formed on both surfaces of said polyester film and comprises a polymer containing ammonium base, a polymer containing polyethylene glycol and a crosslinking agent, and at least one release layer formed on at least one surface of said coating layers.
摘要:
The present invention provides an optical pressure-sensitive adhesive sheet excellent in the productivity, and is reduced in the remaining of an air bubble after an autoclave treatment or the generation of a delayed bubble when laminating the optical pressure-sensitive adhesive sheet to an optical member. The present invention relates to an optical pressure-sensitive adhesive sheet, which comprises an acrylic pressure-sensitive adhesive layer, wherein the acrylic pressure-sensitive adhesive layer is formed by an active energy ray polymerization, a gel fraction of the acrylic pressure-sensitive adhesive layer is 80 wt % or less, and a content of a component having a molecular weight of 50,000 or less in a sol matter of the acrylic pressure-sensitive adhesive layer is 20 wt % or less.
摘要:
The present invention provides a laminated polyester film which is excellent in adhesion to a light diffusion layer or an anti-sticking layer, etc., when these layers are formed thereon. The laminated polyester film of the present invention comprises a polyester film and a coating layer formed on at least one surface of the polyester film, which coating layer is produced by applying a coating solution comprising an acrylic resin, an epoxy compound and an oxazoline compound thereonto. In the laminated polyester film of the present invention, a content of the acrylic resin in the coating layer is 20 to 90% by weight, a total content of the epoxy compound and the oxazoline compound in the coating layer is 10 to 80% by weight, and a weight ratio between the epoxy compound and the oxazoline compound (epoxy compound:oxazoline compound) is 1 to 10:1 to 10.
摘要:
The present invention provide a laminated polyester film which is capable of ensuring a good dimensional stability without being subjected to such a surface saponification treatment with an alkali solution as required for triacetyl cellulose films, is available at low costs, exhibits a good adhesion property to adhesives and a high total light transmittance, and can be suitably used as a protective film for polarizing films. The laminated polyester film of the present invention comprises a polyester film; a coating layer formed on one surface of the polyester film which comprises an acrylic resin or a urethane resin as a main component; and a coating layer formed on the other surface of the polyester film which comprises a urethane resin having a polycarbonate structure. In the preferred embodiment of the present invention, the coating layer comprising the acrylic resin or the urethane resin as a main component has a thickness of 0.04 to 0.15 μm, and the polyester film comprises an ultraviolet absorber.
摘要:
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.
