摘要： PROBLEM TO BE SOLVED: To provide an optical functional membrane which has excellent gas barrier property such as moistureproofness firstly, and to provide an antiglare-antireflection film which has antiglare property and antireflection property at the same time and can reduce reflection of light in the interfaces of layers inside the film and its manufacturing method secondarily. SOLUTION: On a transparent substrate film 11, an antiglare layer 12 whose surface is finely uneven is formed directly or through another layer, and further a low-refractive-index layer 13 having a lower refractive index than that of the antiglare layer 12 is formed thereupon. The antiglare layer 12 has a higher refractive index than that of a layer in contact with the surface of the low refractive index 13, the surface being on the opposite side from the surface with which the antiglare layer 12 is in contact. An SiO x film may be used for the low refractive index 13. The SiO x film itself has excellent gas barrier property as an optical functional membrane and is excellent in moistureproofness, scratch resistance, adhesion to a substrate, transparency, low-refractive-index property, dye deterioration prevention property, etc. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To prevent the damage of a hard coat film due to the concentration of stress as well as to enhance the surface hardness and to obtain a hard coat film hard to be scratched by making the elastic modulus of a hard coat layer formed nearest to a transparent substrate higher than that of a hard coat layer as a surface layer. SOLUTION: Hard coat layers 2, 2' are formed on one side of a transparent substrate 1 in 10-50 μm total thickness to obtain the objective hard coat film. The hard coat layer 2 contains 20-80 mass% inorganic fine particles and the elastic modulus of the hard coat layer 2 is higher than that of the hard coat layer 2'. An adhesive layer 3 comprising a known adhesive may be disposed on the other side of the substrate 1 so as to stick the hard coat film to an object to be coated.

摘要： PROBLEM TO BE SOLVED: To produce a highly functional high-quality thin film by a coating method, i.e., a method advantageous in terms of mass production and equipment cost. SOLUTION: A transparent resin substrate is coated, directly or through another layer, with a metal oxide sol formed by the hydrolysis of a lower metal alkoxide, Rm Ti(OR')n (wherein R is a 0-10C alkyl; R' is a 1-10C alkyl; and m+n is 4) or a metal alkoxide, Rm Ta(OR')Rn (wherein R is a 0-10C alkyl; R' is a 1-10C alkyl; and m+n is 5), and the resulting coating layer is exposed to an active energy ray, thus giving an optically functional film.

摘要： PURPOSE:To prevent curling, waving, blistering, maloder and the like from developing by a method wherein the base material of the heat-transfer image receiving sheet concerned is produced by laminating foamed polyolefin layer on at least one side of core material through thermosetting, cold-setting or moisture-curing adhesive. CONSTITUTION:The heat-transfer image receiving sheet has base material, which is produced by laminatingly bonding two foamed polyolefin films 2 and 2' on at least one side of core material 4 through thermosetting, cold-setting or moisture-curing solventless adhesives 1 and 1' under the condition that dye- accepting layer 3 is provided on the front surface of the base material. As the above-mentioned adhesives 1 and 1', matter mainly made of urethane-based prepolymer having isocyanate group at the terminal of the molecule or of oligomer and reactive polymer or of oligomer is employed under the condition that its viscosity at 65 deg.C lies within the range of 500-9,000cps. Thus, heat transfer image receiving sheet having high surface smoothness is obtained without developing curling and the like.
