摘要： PURPOSE:To obtain the liquid crystal display element which exhibits a high voltage holding rate, has an adequately high pretilt angle and has high reliability even at the time of long-time use by using a compsn. for liquid crystal oriented films contg. a polymer Z having a specific unit structure. CONSTITUTION:This compsn. has the polymer Z having the unit structure expressed by formula I and/or formula II. In the formula, A denotes a residual tetracarboxylic group having a spiro ring; Y denotes a residual arom., aliphat. or alicyclic diamine group. The compsn. for liquid crystal orientation is formed by adding an org. solvent, additive, etc., at need to the org. solvent soln. of this polymer Z. This compsn. is applied on a prescribed electrode substrate surface by a spinner method, dipping method, etc., and is then calcined by heating, by which the liquid crystal holding substrate formed with the liquid crystal oriented film on the electrode substrate surface is formed. The liquid crystal display element in such a case is produced by using a pair of such liquid crystal holding substrates, holding and sealing a liquid crystal chiral agent, etc., between these substrates to constitute a liquid crystal cell and properly mounting attachments, such as polarizing plates, thereto.

摘要： PURPOSE:To obtain an optical recording medium capable of regenerating recorded data due to a change between amorphous phases without any shape variation and of formation of a protecting layer on a recorded layer without a crystallization phenomenon by laminating a recorded layer which contains a specific naphthalocyanine derivative as a main component and indicates a change in optical properties due-to a phase variation through irradiation with energy. CONSTITUTION:A phase-variable optical recording medium contains a naphthalocyanine derivative expressed by formula (I) as a main component which is applied to a substrate. This medium also consists of a recorded layer which-is subjected to a phase change by irradiation with energy and a subsequent change in optical properties. In formula (I) of the naphthalocyanine derivative, R1 which is a substitution group is significant (6 or more carbon atoms),so that the molecules of a formed naphthalocyanine derivative film changes between the amorphous phases due to heat such as of laser. In this case, the phase change is such as a change in optical properties not accompanied by changes such as shape, film thickness and crystallization.

CONSTITUTION:A polymer containing ester as a constituent component is obtained by the homopolymerization or copolymerization of (meth)acrylic alicyclic ester or the copolymerization of said ester and other copolymerizable unsaturated monomer and pref. used in an amount of 100 - 5% by wt. of the total monomer. As M of a naphthalocyanine derivative represented by formula, there are metals of Groups Ib, IIa, IIb, IIIa, IVa, IVb, Vb, VIb, VIIb or VIII and oxides, halides or hydroxides thereof and, as Q, there are an alkyl group, an aryl group, an alkyloxy group or halogen. This optical recording medium is prepared by coating a substrate with a solution prepared by dissolving the naphthalocyanine derivative represented by the formula in carbon tetrachloride and drying the coating layer. As a result, the optical recording medium excellent in reflectivity is obtained.

摘要： PROBLEM TO BE SOLVED: To provide a manufacturing method of the substrate for a plasma display panel, which enables manufacture of a high-definition plasma display panel in few processes, easily and with good yield. SOLUTION: A dielectric layer and a block-forming resin compound element which comprise a support film, (A) a resin compound layer containing polymer binding agent, having ethylene non-saturation group and an inorganic material and (B) a resin compound layer, containing binder polymer and an inorganic material are laminated on a substrate, so that the (B) layer is brought into contact with the substrate, and then the support film is removed. When a base body, having a recessed part is crimped so that the face having the recessed part contacts the (A) layer, the crimping of the base body is made, after a layer made of a mold lubricant has been formed on the surface of the (A) layer or the surface having the recessed part of the base body, and then the base body having the recessed part is removed. After a pattern has been formed corresponding to the recessed part of the base body, the pattern of the dielectric layer consisting of the (A) layer and the (B) layer and the block-forming resin compound is subjected to calcinations, so as to manufacture the substrate for the plasma display panel.
