20130172476 | FLUORINE-BASED SURFACTANT, AND COATING COMPOSITION AND RESIST COMPOSITION EACH USING THE SAME - Provided is a fluorine-based surfactant including a copolymer synthesized by copolymerizing, as essential monomers, a polymerizable monomer (A) having a poly(perfluoroalkylene ether) chain and polymerizable unsaturated groups at both ends of the chain and a polymerizable monomer (B) having an oxyalkylene group and a polymerizable unsaturated group. The fluorine-based surfactant cannot structurally generate PFOS or PFOA, which tend to accumulate in the environment and living bodies; even when the fluorine-based surfactant has lower fluorine content than surfactants having a fluoroalkyl group having 8 or more carbon atoms, the fluorine-based surfactant has a higher capability of decreasing surface tension than the surfactants. Accordingly, the fluorine-based surfactant can be suitably used as a leveling agent for a coating composition, a resist composition, or the like. | 07-04-2013 |
20130172463 | INORGANIC FINE PARTICLE DISPERSANT AND INORGANIC FINE PARTICLE DISPERSION USING THE SAME - Provided is a inorganic fine particle dispersant comprising, as an essential component, a compound resin (A) in which a polysiloxane segment (a1) having a structural unit represented by general formula (1) and/or general formula (2) and a silanol group and/or a hydrolyzable silyl group is bonded to a vinyl-based polymer segment (a2) through a bond represented by general formula (3). An inorganic fine particle dispersion liquid that contains the inorganic fine particle dispersant and inorganic fine particles, an inorganic fine particle dispersion containing the inorganic fine particle dispersion liquid, a paint, and a cured product are also provided. | 07-04-2013 |
20130168138 | SUBSTRATE HAVING TRANSPARENT CONDUCTIVE LAYER, METHOD FOR PRODUCING SAME, TRANSPARENT CONDUCTIVE FILM LAMINATE FOR TOUCH PANEL, AND TOUCH PANEL - A substrate having a transparent conductive layer has a transparent conductive pattern that is not easily visually recognizable by a naked human eye on a transparent substrate and can be formed by a simple and efficient method. In the case where a transparent conductive pattern is formed on a transparent substrate, the pattern region does not include conductive regions covered with uniform transparent conductive films or a high-resistance region that is not covered with the transparent conductive film, the high-resistance region electrically insulating the conductive regions. Instead of the conductive regions or the high-resistance region, the inventors use a region having a structure including a mixture of a portion covered with the transparent conductive film and a portion not covered with the transparent conductive film, thereby solving the foregoing visual recognition issue. | 07-04-2013 |
20130158186 | OXYGEN-BARRIER FILM AND ADHESIVE - An oxygen-barrier film and an adhesive used therefor. Provided are an adhesive, which can be used for packaging foodstuffs and contains mainly a polyester having excellent oxygen-barrier properties, and an oxygen-barrier film that uses the adhesive. The oxygen-barrier film is prepared using an adhesive that includes: an amorphous polyester polyol, which is obtained by polycondensation of a polyvalent carboxylic acid component including at least one type of ortho-oriented aromatic dicarboxylic acid or anhydride thereof, and a polyhydric alcohol including at least one compound selected from the group consisting of ethylene glycol, propylene glycol, butylene glycol, neopentyl glycol and cyclohexanedimethanol, and a curing agent capable of reacting with the amorphous polyester polyol. | 06-20-2013 |
20130158149 | ACTIVE-ENERGY-RAY-CURABLE HOT-MELT URETHANE RESIN COMPOSITION, MEMBER FOR ELECTRONIC DEVICE, THE MEMBER INCLUDING THE RESIN COMPOSITION, AND PACKING - An active-energy-ray-curable hot-melt urethane resin composition contains a hot-melt urethane and an active energy ray polymerization initiator, the hot-melt urethane being obtained by converting more than 50% and 100% or less of the total number of isocyanate groups in an isocyanate group-terminated urethane prepolymer into terminal (meth)acryloyl groups by a reaction with hydroxyl groups in a reactive functional group-containing (meth)acrylic compound, the isocyanate group-terminated urethane prepolymer being obtained by reacting a polyisocyanate component with a polyol component that contains an aromatic polyester polyol containing a 2,2-dimethyl-1,3-propylene structure in its molecule in an amount of 90% by mole or more of a glycol component and a polyol other than the aromatic polyester polyol. The hot-melt urethane resin composition has excellent properties such as hot melting, rapid curability, a shape-retaining property after being applied, flexibility, durability, a property of adhering to a base, a low outgas property, mechanical strength, and flame retardancy. | 06-20-2013 |
