PURPOSE:To provide a thermal recording material using a beam of light such as laser, high in sensitivity, at low cost and easy to produce and maintain, by a method wherein a metal, a semimetal or the like is ion-plated on a base under a partial pressure of oxygen to produce a recording layer. CONSTITUTION:A metal (e.g., Zn, In), a semimetal (e.g., Bi, As, Sb) or a semiconductor (e.g., Ge, si) is deposited on the base (e.g., a polyethylene terephthalate film) by high-frequency ion plating under a partial pressure of oxygen of preferably 10<-2>-10<-4>Torr to produce the recording layer. Further, if required, a reflection-preventing layer consisting of SnS, GeS or the like or a protective layer consisting of Al2O3, a resin or the like is provided on the recording layer by vapor deposition, coating or other method to obtain the objective recording material. EFFECT:Free from environmental pollutions, and excellent in the quality of recorded images. |
