METHOD OF PRODUCING CYCLIC POLYOLEFIN FILM, CYCLIC POLYOLEFIN FILM PRODUCED BY THE PRODUCTION METHOD, METHOD OF PREPARING LIQUID DISPERSION OF FINE PARTICLES, LIQUID DISPERSION OF FINE PARTICLES AND METHOD OF PREPARING DOPE

摘要

A method of producing a cyclic polyolef in 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.
