Abstract

PURPOSE: To enable recording with deeply colored dots or reading indistinct characters, by mixing a benzendithiol nickel complex into a laser beam recording-reading medium so that the medium will be easily melted and vaporized by laser beams in a specified zone.
CONSTITUTION: A high molecular organic compound (e.g. PVA, nitrocellulose, etc.) is added as a binder into a solvent to form a liquid, or an organic coloring agent [e.g. 3,3-bis-(p-dimethyl aminophenyl) phthalide or the like], an acidic substance and a binder are added into a solvent to form a liquid. Into this liquid is added a benzendithiol nickel complex having the formula (X is H, Cl, Br or CH3, n is 1W4; and A is a quanternary ammonium radical). The obtained laser beam recording-reading medium has a sensitivity to a wave length in the zone of 800W 950mm. Owing to this medium, a spot exposed to radiation of laser beams is recorded as a deeply colored dot.
