Abstract:
A light-illuminating rod comprising (a) a flexible rod member formed from a light-piping plastic material and (b) a light diffusible reflective film which is fixedly bonded to part of the outer periphery of the rod member along the longitudinal direction thereof and which comprises (i) a light-transmittable polymer and (ii) light diffusible reflective particles dispersed in the polymer, said light transmittable polymer of the light diffusible reflective film having a storage modulus of 1.0Ã—104 to 1.0Ã—108 dyne/cm2 as measured by a viscoelastic spectrometer and said light transmittable polymer 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, and said light diffusible reflective particles contain from 10 to 100% by weight of an inorganic material based on the amount of light diffusible reflective particles.
