Optical disc

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;
• 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;
• a loss tangent (tanδ) at 60° C. in the dynamic viscoelastic spectrum of the cured film measured at a frequency of 3.5 Hz is 0.25 or less;
• and
• the cured film has a glass transition temperature of 50° C. or less.
