    Abstract: PROBLEM TO BE SOLVED: To provide an optical recording medium and a method of forming a printable layer on the optical recording medium, particularly an optical recording medium having a printable layer with high glossiness and a method of forming the printable layer.SOLUTION: The optical recording medium comprises a first blotting layer formed from a heat-curable blotting material on an outermost layer at an opposite side of a recording/reading surface; and a second blotting layer formed from a UV-curable blotting material on an inner side of the first blotting layer. The optical recording medium has a printable layer with high glossiness such that a surface of the first blotting layer is printed with cyan, magenta, yellow and black inks to have an average glossiness at an angle of 20 degrees greater than or equal to 30 (GU), an average glossiness at an angle of 60 degrees greater than or equal to 70 (GU), and an average glossiness at an angle of 85 degrees greater than or equal to 88 (GU).

    Abstract translation: 要解决的问题：提供光学记录介质和在光学记录介质上形成可印刷层的方法，特别是具有高光泽度的可印刷层的光学记录介质和形成可印刷层的方法。解决方案：光学 记录介质包括在记录/读取表面的相对侧的最外层上由热固化印刷材料形成的第一印迹层; 以及由第一印迹层的内侧上的UV固化印迹材料形成的第二印迹层。 光学记录介质具有高光泽度的可印刷层，使得第一印迹层的表面用青色，品红色，黄色和黑色油墨印刷，以使平均光泽度为大于或等于30°的角度（GU ），大于或等于70（GU）的60度角度的平均光泽度和大于或等于88度（GU）的85度角度的平均光泽度。

    Abstract: The present invention provides a spin coater including a rotation table that rotatably holds the disc substrate, a spin-cup that surrounds the outer circumference of a disc substrate held on the rotation table, a dripping unit configured to drip an ultraviolet-curable resin composition onto the surface of the disc substrate, a rotating unit configured to rotate the disc substrate via the rotation table to spread the ultraviolet-curable resin composition over the surface of the disc substrate, a heating unit configured to heat the ultraviolet-curable resin composition on the disc substrate, and a temperature controlling unit configured to control a reaching temperature of the spin cup which is increased by the heating unit each time the ultraviolet-curable resin composition is spread, so as to be constant over multiple spin coating processes.
