OPTICAL RECORDING MEDIUM AND INK COMPOSITION

摘要

[Object]: An optical recording medium having a capability of high quality printing is provided by increasing the gloss level of a print-receiving layer formed on a label face thereof. [Method to address the problem]: An optical recording medium 200 is characterized in that a print-receiving layer 20 capable of being printed with ink is disposed on the face opposite to the light incident side of a recording/reading functional layer 10 that is a substrate surface incident type medium; the print-receiving layer 20 has a filler-containing layer 22 containing as a main component a hydrophilic resin and an organic filler or inorganic filler and a filler-free layer 21 that is laminated on the filler-containing layer 22 and contains no organic filler or inorganic filler; and the filler-containing layer 22 is composed of a first filler-containing layer 222 disposed on the side of the recording/reading functional layer 10 and a second filler-containing layer 221 that is in contact with the filler-free layer 21 and contains an organic filler or inorganic filler in an amount larger than the amount contained in the first filler-containing layer 222.
