COATING FOR OPTICAL RECORDING

摘要

A coating composition (20) for optical recording includes a uniform dispersion of polymer particles (30) in a liquid (40), a quantity of dye particles (50) uniformly dispersed in the liquid, the dye particles being soluble in the polymer but substantially insoluble in the liquid, and a quantity of radiation absorber material adapted to absorb radiation (60) at a wavelength of a laser for optical recording of an image (70).
