Abstract
A light-illuminating rod comprises a flexible rod member formed from a light piping plastic material and a light diffusible reflective film which is fixedly bonded to part of the outer periphery of the rod member along the longitudinal direction thereof. The light diffusible reflective film comprises a light-transmittable polymer and light diffusible reflective particles dispersed in the polymer. The light-transmittable polymer contains from 10 to 100% by weight of an adhesive polymer based on the total amount of the light-transmittable polymer. The light-transmittable polymer further contains from 2 to 90% by weight of a dispersible polymer having hydrophilic functional groups within the molecule based on the total amount of the light-transmittable polymer. In one embodiment, the light diffusible reflective particles contain from 10 to 100% by weight of an inorganic material based on the total amount of the light diffusible reflective particles.
