摘要： Provided is an optical disc in which at least a light reflecting layer and a light transmitting layer that includes a cured film of an ultraviolet curable composition are stacked on a substrate, and information is reproduced by making a blue laser beam be incident on the optical disc from a side of the light transmitting layer, wherein an elastic modulus (25° C.) measured by indenting a Vickers indenter having a vertex angle of 136° under a load of 100 mN into a surface of the cured film of the ultraviolet curable composition is 1,500 MPa or less; and a loss modulus (E″) at 60° C. in a dynamic viscoelastic spectrum of the cured film measured at a frequency of 3.5 Hz is 10 MPa or less. Thus, warpage is reduced during curing and plastic deformation is less likely even under a load for a long period of time.

摘要： An ultraviolet curable composition having, a coating film cured with ultraviolet rays with a large number of crosslinking points due to a (meth)acrylate compound that does not intramolecularly have a cyclic moiety and has a functionality of three or more and, the compound does not intramolecularly have a cyclic moiety, plastic deformation due to a cyclic moiety is less likely to occur. Additionally, a monofunctional (meth)acrylate compound forms a homopolymer having a glass transition temperature of 20° C. or less, has a low glass transition temperature, and is flexible. Curing contraction caused in ultraviolet curing is suppressed and plastic deformation is less likely in the resultant cured film at room temperature. An optical disc employing the above ultraviolet curable resin composition reduces warpage; and rapid recovery from deformation caused even by application of a load for a long period of time or as a result of an impact due to falling.
摘要翻译：一种紫外线固化性组合物，其具有由于不分子内具有环状部分而具有3个以上的官能度的（甲基）丙烯酸酯化合物而具有大量交联点的紫外线固化的涂膜，所述化合物不在分子内具有环状部分，不太可能发生由于环状部分引起的塑性变形。此外，单官能（甲基）丙烯酸酯化合物形成玻璃化转变温度为20℃以下的均聚物，玻璃化转变温度低，柔软。紫外线固化引起的固化收缩被抑制，并且在室温下所得的固化膜的塑性变形不太可能。使用上述紫外线固化树脂组合物的光盘减少翘曲; 并且即使施加负载长时间或由于下降引起的冲击的结果，也能够快速恢复变形。
