    摘要: The present invention provides a disc-shaped information medium comprising a printable layer which comprises an undercoat layer and a colorant receiving layer, wherein: the colorant receiving layer comprises microparticles, a binder and a cross-linking agent; a thickness of the colorant receiving layer progressively decreases from an inner circumferential side to an outer circumferential side thereof; and a relationship between a thickness (T in ) at an inner peripheral portion of the colorant receiving layer and a thickness (T out ) at an outer peripheral portion of the colorant receiving layer satisfies the equation of (T in - T out ) ≥ 1 µm. The present invention further provides a method for producing the disc-shaped information medium.
