An optical disk comprising a first substrate and, sequentially superimposed thereon, a first reflection film for reflecting laser beams for information reading and a resin layer consisting of a coating resulting from hardening of an ultraviolet hardenable composition, wherein the first reflection film is one constituted of silver or an alloy whose main component is silver and wherein the ultraviolet hardenable composition comprises a radical polymerizable compound (a), a compound of the following formula (1) (b) and a radical photopolymerization initiator (c).

L'invention concerne un disque optique comprenant un premier substrat, sur lequel sont appliqués successivement une première pellicule réfléchissante permettant de réfléchir les faisceaux laser servant à la lecture des données, et une couche de résine comprenant un revêtement produit par durcissement d'une composition durcissant aux ultraviolets. La première pellicule réfléchissante est une pellicule d'argent ou d'un alliage à base d'argent, et la composition durcissant aux ultraviolets contient un composé (a) à polymérisation radicalaire, un composé (b) représenté par la formule (1) ci-après, et un amorceur (c) de photopolymérisation radicalaire.
