Document Type and Number:
Japanese Patent JP4566538
Kind Code:

Abstract:
A solvent and TAC particles are continuously supplied to a disperser. When the shearing of the solvent and the particles are made in a shearing section, the particles are dispersed in the solvent. The dispersion is fed to a mixer in one minute. The shearing of the dispersion is made in the mixer, the particles are swollen in the solvent in one minute. Since the shearing and the continuous feed of the swelling solution is made, the aggregation does not occur. There are no undissolved aggregates in a dope, which is obtained from the swelling solution. A film produced from the dope has no defects of luminescent spot but excellent optical properties.
