  • Patent number: 6322868
    Abstract: Composition and use of polymers in appropriate solvent(s) with or without addition of selected dye combinations are proposed for developing a thin-layer coating on the transparent layer of optical storage media such as audio and video CDs, laser discs (LD) and DVDs for improvement of the sound and/or video quality during either recording and/or playback of the encoded digital information. The invention can also be incorporated in manufacture of recordable (CD-R) and re-writeable CD (CD-RW) media. In that case, the proposed composition is applied on the polycarbonate transparent surface of optical storage media at the final stages of recordable media manufacturing.
