摘要： A polyimide precursor composition which is produced by (i) providing a polyamide acid solution obtained by reacting an aromatic tetracarboxylic acid component and a diamine component in the presence of an oxygen-containing solvent and (ii) subjecting said polyamide acid solution to heat treatment. The polyimide precursor composition exhibits a desirable apparent viscosity and a desirable thixotropic property and it excels in film forming ability, and because of this, it enables the formation a high quality relief pattern film with no defect and which excels in form retention by way of the screen printing. Further, the polyimide precursor composition is extremely suitable for the formation of a relief pattern by way of screen printing in the production of electronic, electric, optical, or precision devices, wherein the relief pattern is required to have a reduced dielectric constant and a reduced residual stress and to have a sufficient heat resistance, moisture resistance, physical strength, and chemical stability.

摘要： The invention relates to a fluorine-containing resin (graft copolymer) used for preparing a paint. This resin is prepared by a graft copolymerization of a fluorine-containing copolymer with a first monomer composition. The fluorine-containing copolymer comprises a first constitutional unit derived from a fluoroolefin and at least one of second and third constitutional units. The second constitutional unit is derived from a particular carboxylic acid vinyl ester represented by a general formula of R--C(.dbd.O)OCH.dbd.CH.sub.2 where R is a special group. The third constitutional unit is derived from a first monomer which is at least one compound selected from vinyl ethers and allyl ethers. The first monomer is represented by a general formula of R--O--(CH.sub.2)n--CH.dbd.CH.sub.2. The first monomer composition for preparing the resin contains a second monomer which is at least one compound selected from methacrylic acid esters and acrylic esters. The second monomer is represented by a general formula of CH.sub.2 .dbd.C(--R')C(.dbd.O)O--R where R' is hydrogen atom or methyl group. A composition prepared by mixing the resin with vinylidene fluoride resin or with a combination of vinylidene fluoride resin and acrylic resin is capable of providing a coated film having high gloss, high weather resistance, and good results in bending test for a long time. Another composition prepared by mixing the resin with a hardener is capable of providing a coated film having high hardness, good adhesion to various other coated films, high weather resistance, and high stain resistance.

摘要： In a process for preparing an aromatic urethane which comprises reacting an aromatic nitro compound, an organic compound containing at least one hydroxyl group, and carbon monoxide at elevated temperature and pressure in the presence of a catalytic system composed of a catalyst consisting of a platinum metal, a platinum metal compound, and/or a platinum metal compound-containing compound and a promoter consisting of a Lewis acid and/or a Lewis acid-containing compound, an organic primary amino compound, a urea compound, a biuret compound, an allophanate compound, or a mixture thereof is added to the reaction system whereby the reaction rate is increased and the yield of the desired product is enhanced. For example, 2,4-diethylcarbamatetoluene can be prepared in quantitatively high yield by reacting 2,4-dinitrotoluene, ethanol, carbon monoxide, and a small amount of aminonitrotoluene at elevated temperature and pressure in the presence of palladium chloride and ferrous chloride-pyridine complex.
