摘要： PURPOSE:To provide such a plastic optical sheet that even when a pattern electrode and outer leads of controlling ICs are connected altogether by thermocompression bonding, no trouble is caused but the sheet shows excellent thermal dimensional stability, by specifying the layer structure. CONSTITUTION:This optical sheet consists of a hard three-dimensionally crosslinked layer (H) having high softening point comprising an imide resin having >=H surface hardness by JIS K5400 (under 100g load) and >=130 deg.C thermal deformation temp., core layer V having gas barrier property, and adhesive layer A comprising a hardened material of a nonsolvent type hardening resin. These layers are laminated to form a structure of H/A/V or H/A/V/A/H. Since the hard three-dimensionally crosslinked layer H having high softening point is formed as the surface layer, such a problem can be avoided that when a patterned electrode and outer leads are connected with an anisotropic conductive sheet inserted between these by thermocompression bonding, conductive particles do not deform during thermocompression bonding but the electrode substrate is dented by the conductive particles. The layer H consists of, for example, a three-dimensionally crosslinked layer of polyamide imide.

摘要： PURPOSE:To obtain a heat-resistant high-light-transmittance polyimide resin which is a copolyimide comprising specified repeating units and produced by reacting a tetracarboxylic anhydride with a diisocyanate in a polar solvent. CONSTITUTION:An aromatic tetracarboxylic anhydride such as diphenyl ether 3,3'-4,4'-tetracarboxylic anhydride is reacted with a diamine of formula I (wherein R1 and R2 are each H or 1-4C alkyl) or the corresponding diisocyanate in a nonamidic polar solvent having a permittivity of 5 or above desirably 15 or above at 20 deg.C or 25 deg.C for example diglyme to produce a copolyimide comprising repeating units of formulas II and III (wherein R0 is O, CO or the like; and Ar is a specified bivalent organic group). This polyimide is not only heat-resistant but also soluble in a low-boslong lawly hygroscopic solvent and can give a polyimide resin molding having a markedly high light transmittance. Further, it can give varnishes when dissolved in nonamidic solvents such as dioxane and tetrahydrofuran as well as dimethylacetamide, etc.

摘要： PROBLEM TO BE SOLVED: To improve the dispersibility and the packing property of micronized magnetic particles and to attain excellent durability by containing a polyimide base resin in a magnetic layer. SOLUTION: The polyimide based resin is contained in the magnetic layer of a magnetic recording medium formed by applying a magnetic material prepared by dispersing ferro magnetic powder in a binder on a non-magnetic supporting body. The polyimide based resin is preferably a polyamide-imide resin containing an alicyclic structure, a polyimide based resin containing a sodium sulfo oxy group and particularly a polyimide base resin obtained by copolymerizing with monosodium 5-sulfo oxy isophthalate. Because such the polyimide based resin is improved in the solubility in a low b.p. solvent and the dispersibility of the magnetic powder without damaging the wear resistance of the polyimide based resin, the magnetic recording medium excellent in the packing property of the magnetic powder, electromagnetic conversion characteristic, heat resistance and travelling durability is obtained.

摘要： PROBLEM TO BE SOLVED: To facilitate the movement of the active material so as to improve the charging and discharging capacity of a battery, and to provide a soft electrode collector due to the porosity thereof so as to improve the winding work by forming fine holes in a binder resin layer of at least one of a negative electrode and a positive electrode of a nonaqueous electrolyte secondary battery. SOLUTION: Paste obtained by agitating and kneading the binder resin and a solvent, which dissolves the binder resin and which can be mixed with water, and an active material carrier is coated on a metal foil such as an aluminum foil and a copper foil, and thereafter, a non-solvent of the binder is mixed with the solvent, and coagulated, and dried. When the coated paste is solidified by the desolvent during the coagulation, a substitution between the coagulant and the solvent of the binder resin is generated, and fine through holes are generated in the binder resin layer so as to facilitate the movement of the active material, and a battery, in which a charging and discharging loss is reduced, can be obtained. Hole diameter of the fine holes is desirably set in a range from several angstrom to several micron on a point of permeability of lithium ion. As a binder resin, polyimide, polyamide and polyamideimide is used.
