Abstract
The optical recording material of the invention is an optical recording material used for an optical recording medium capable of recording information by irradiation of light, the optical recording medium being an optical recording medium which records information at a linear speed of at least 14 m/sec, wherein the dye component in the optical recording material comprises at least one type of chelate compound of an azo compound and a metal, and when the dye component is used as a sample for thermogravimetry in an inert gas atmosphere, the dye component sample exhibits a maximum weight reduction of 0.2-3.0%/° C. at 180-250° C.
