PURPOSE:To enable the illumination highly variable in colors without the intervention of a color filter by providing the colored resin coated film having requisite light transmittance on the surface. CONSTITUTION:The coated films of the colored copolymeric polyamide resins, etc., of the resins having >=50% light transmittance of max. absorption wavelength and a high thin film adhesive property, with reduced damage by an org. solvent and soluble in a lower alcohol is formed on the surface of the plastics optical fiber provided to a protecting treatment for light side-leakage, and desired colors are combined. When the colored optical fiber is used, the structure is simplified and miniaturized without using a color filter as the light source, and the illumination highly variable in colors can be performed. |
