Abstract
An optical recording medium of the present invention includes a disk body and an ink-receiving layer disposed on a label surface of the disk body, wherein the ink-receiving layer has a brightness ofor more, a chroma of 4 or less, and an average surface roughness (Ra) of 0.1 μm or less. Therefore, a colored layer of white ink need not be provided below the ink-receiving layer to simplify the manufacturing process. Furthermore, even when the ink-receiving layer is formed by a spin coating or slit coating process in which the surface quality of an 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.
