  • INFORMATON RECORDING MEDIUM AND MANUFACTURING METHOD OF THE SAME
    Publication number: 20090169798
    Abstract: Disc-shaped information recording medium comprising optical penetrating substrate having colored underlayer and ink receipt layer in this order on the principal surface of one side of the substrate, wherein the ink receipt layer contains inorganic fine particles, a binder, and a crosslinking agent, and wherein a pore diameter distribution of a gap of the ink receipt layer has a maximum peak in the range of 30 nm or more when the ink receipt layer is measured with a mercury porosimetry method. Since the shrinkage force functioning in the pores of the gaps of the ink receipt layer weakens, a disc-shaped information recording medium having a reduced occurrence of warp is provided.
