ABSTRACT:
A method for manufacturing an optical recording medium of the present invention includes the steps of forming an underlying layer having a brightness of 8 or more and a chroma of 4 or less on a label surface of a disk body by a spin coating process, and forming an ink-receiving layer on the underlying layer. In the present invention, the underlying layer having a brightness of 8 or more and a chroma of 4 or less is formed by a spin coating process, thereby significantly decreasing the surface roughness of the underlying layer. Even if the ink-receiving layer is formed by the spin coating or slit coating process in which the surface quality of the underlying layer is greatly reflected, therefore, the average surface roughness (Ra) of the ink-receiving layer can be significantly decreased. Thus, printing by an ink jet printer can produce a color and brilliance close to those of a silver salt photograph.
