ABSTRACT:
Optical recording medium includes a substrate, a coloring agent layer formed on the substrate, a light absorber layer formed on the coloring agent layer and a developer layer formed on the light absorber layer. The coloring agent layer is separated from the developer layer by the light absorber layer and the lamination layer composed of these layers has a uniform thickness. The optical recording medium is produced by vacuum depositing a coloring agent, a light absorber and a developer successively on the substrate to form a multi-layer construction, the substrate being capable of transmitting visible light and near infrared light. Alternatively, the optical recording medium contains a plurality of lamination layers mentioned above. The optical recording medium has a high contrast and achieves a high speed multi-color recording.
