である。This method involves applying a thin layer of liquid radiant M@-containing lacquer on the surface of a master mold for transfer, such as a master disc or a stamper (a metal scrap mold made by transferring from a master disc by electroforming). Place a colorless transparent plastic substrate on top,
Radiation is irradiated with a laminated egg holding a single layer of lacquer [7] The Plus Deck substrate, which is integrally bonded with a lacquer 8" bow-toe Jl, is peeled off from the mold 1 for transfer to produce an information recording carrier.

密着性が悪い。[2However, conventional information recording carriers are generally used as N1 radiation-curable lacquers, typically monomers or sligomers having unsaturated bonds, particularly low-molecular-weight mono-, di-, tri- or tetra-acrylic acid esters as suitable monomers. However, the adhesion of the plastic substrate (cast acrylic plate /i) is poor.

うにして調らべた。In this case, the releasability from the nickel stamper, the transfer efficiency of the signal bits of the obtained information recording carrier, and the adhesion between the hardened lacquer layer and the acrylic plate were investigated, and the results are shown in Table 1. The transfer efficiency of each signal pit was investigated as follows.

いうことが言える。The beam diameter is set to approximately 1 on the A4 evaporation information recording carrier created by transfer.
．． By sweeping the body laser at a wavelength of 780 μm, which is set to 6 μφ, the presence or absence of a signal bit is reproduced by a change in reflectance, and the degree of change in reflectance is expressed as a relative value. It can be said that the larger the 11"1 ratio of the change in reflectance, the better the transfer efficiency.

, 2-Propanedione-2-(0-ethoxycarbonyl)oxime (Kankukikoa PDO) All two parts IJII and the radiation-curable lacquer 100 were prepared in the same manner as in Example 1. As is clear from the table, the adhesion between the lacquer layer and the substrate is greatly improved by including all the organic solvents capable of dissolving the plastic substrate as a component of the radiation-curable lacquer as in the present invention.
