20100104853 | FOAM TAPE - Provided is a foam tape including a foam and an adhesive layer. Since interfacial adhesion strength between the foam and the adhesive layer is improved through corona treatment, the foam tape can support heavy articles, even at high temperature, for a long time. Also, a manufacturing process for a foam tape is provided, by which the foam tape can be simply prepared, and the manufacturing cost can be reduced. | 04-29-2010 |
20100183189 | IMAGE SIGNATURE CREATING METHOD AND APPARATUS FOR DISCRIMINATING STILL IMAGES - An image signature creating method includes: creating a map by partitioning a still image using rings defined by concentric circles radially spaced apart from each other by a predetermined interval and radial lines circumferentially spaced apart from each other by a predetermined angle, the center of the still image being that of the concentric circles; and creating an image signature from the created map on the basis of distribution of pixels in regions defined by the rings and the radial lines. Accordingly, distribution of illegal contents is prevented and interrupted by search for and discrimination of a still image illegally deformed by a copying of or an intended attack on the still image. | 07-22-2010 |
20110051051 | ACRYLIC PRESSURE-SENSITIVE ADHESIVE COMPRISING OPTICALLY ANISOTROPIC COMPOUND, POLARIZING PLATE AND LIQUID CRYSTAL DISPLAY INCLUDING THE SAME - Disclosed are (A) an acrylic pressure-sensitive adhesive; and (B) an acrylic pressure-sensitive adhesive comprising an optically anisotropic compound having at least one substituent which contains an alkyl group, alkenyl group or alkynyl group at a meta-position of a mesogen. A polarizing plate and a liquid crystal display using the same are also disclosed. The optically anisotropic compound ensures excellent compatibility with the adhesive and high birefringence. Thus, main properties such as adhesion, reliability and durability in the conditions of high temperatures or high temperatures and high humidity are not worsened. Moreover light leakage is prevented by efficiently controlling the birefringence caused by shrinkage stress of the polarizing plate. | 03-03-2011 |
20120121897 | WATER-BASED ADHESIVE COMPOSITION , METHOD FOR MANUFACTURING SAME, AND ADHESIVE FILM - The present invention relates to a water-based adhesive composition, to a method for manufacturing same, and to an adhesive film. The water-based adhesive composition according to the present invention has excellent physical properties such as detachability and reworkability, and can stably prevent changes in the physical properties thereof caused by longitudinal or environmental factors. In addition, the water-based adhesive composition according to the present invention has excellent wettability with respect to various adherends. Accordingly, the water-based adhesive composition according to the present invention can be effectively applied to various industrial adhesive products such as adhesive films for advertisements. | 05-17-2012 |
20130164518 | RESIN COMPOSITION FOR INJECTION COMPRISING LOW BIREFRINGENCE POLYMER BLEND, AND FRONT PANEL PREPARED USING THE SAME - The present invention relates to a resin composition for injection including a low birefringence polymer blend, and a front panel prepared using the same, wherein 2-10 parts by weight of a fluidizing agent is added to the composition based on 100 parts by weight of the polymer blend, and the polymer blend comprises 80-90 wt % of a polycarbonate resin and 10-20 wt % of a negative birefringence polymer resin. It is possible to provide an optical panel using the resin composition for injection, wherein the optical panel is mounted on a front panel of a display such as PDP TVs, LCD TVs, borderless TVs or 3D TVs, and comprises a low birefringence polymer blend plastic resin. | 06-27-2013 |
20130224416 | SILICONE ADHESIVE COMPOSITION FOR A WINDOW FILM HAVING EXCELLENT RELEASE PROPERTIES AND COMPATIBILITY, AND WINDOW FILM USING SAME - Provided are a silicone adhesive composition for a window film, and a window film using same, wherein the composition has excellent release properties for easy release from a window, and also has excellent compatibility with a UV absorbent. The silicone adhesive composition for a window film, according to the present invention, is characterized by comprising: a) 100 parts by weight of a combination of a silicone adhesive and a silicone release agent; b) 1 to 10 parts by weight of a crosslinking agent; c) 0.1 to 2 parts by weight of a platinum based catalyst; and d) 0.1 to 5 parts by weight of an anchoring agent, wherein the weight ratio of the silicone adhesive to the silicone release agent is in the range of 1:1 to 1:0.2. | 08-29-2013 |
