PURPOSE:To obtain a photo-recording medium simply, which is capable of easily recording with excellent reproductivity in quality, by providing a half- mirror layer having a reflectivity of 10% or more and a light transmissivity of 50% or more for the middle of an addition-type photo-recording medium consisting of a transparent supporter A and a recording layer containing a specific naphthalocyanine dye. CONSTITUTION:In the formula 1, R1, R2, R3, and R4 are coincidently or differently a 4-12C straight or branched chain alkyl group, and M is a metal, metal halide, or metal oxide. As a transparent supporter A used, and type of sheeted or filmy materials transmissive to light for recording and regenerating may be cited. A half-mirror layer (c) to be used is obtained by vacuum-vapor deposition, sputtering, ion-plating, coating, etc., of various dielectric substances such as SiO2, TiO2, SnO2, In2O3, etc., or metals such as aluminium nickel, chromium, etc. |
