摘要:
A method of producing a cyclic polyolefin film comprising: dissolving or dispersing a cyclic polyolefin resin and at least one compound selected from a higher fatty acid and a derivative of the higher fatty acid in a solvent; a casting step; a drying step; and a taking-up step; and a method of preparing a liquid dispersion of fine particles, which comprises: subjecting fine particles, an organic solvent and a dispersant to a dispersing treatment, wherein the dispersant contains a cyclic olefin resin.
摘要:
A cyclic olefin resin film, includes: a cyclic olefin resin; and at least one organic compound capable of reducing Rth(λ) in an amount of 0.01 to 30 mass % based on a solid content of the cyclic olefin resin, wherein Rth(λ) is expressed in nm and represents a value of a retardation in a direction of film thickness at a wavelength of λ nm.
摘要:
Artificial marble is produced by laminating a plurality of prepreg sheets formed by impregnating a porous substrate with a melamine resin composition which is composed of melamine resin and a modifier. The melamine resin is an unmodified melamine resin or an alcohol-etherified melamine resin in which formaldehyde-to-melamine molar ratio is between 1.2 to 3.0. The modifier is selected from alcohol, glycol, acrylic monomer, acrylic oligomer and vinyl acetate monomer. The artificial marble has a good stability in dimensions and it is suitable to apply the artificial marble to a composite panel or a decorative laminate panel which is free from tearing even after long time use.
