    摘要： A protective film for optical disks comprising an acrylic adhesive layer disposed on one face of a light transmitting substrate film, wherein a change in transmittance (X) expressed by equation [1] is 10% or smaller and the amount of elution of halogen ions and the amount of alkaline ions from an acrylic adhesive constituting the acrylic adhesive layer are each 10 ppm or smaller; and an optical disk using the protective film. X(%)=[(Ta−Tb)/Ta]×100  [1] (Ta: an initial transmittance of light of 405 nm through the protective film, Tb: a transmittance of light of 405 nm through the protective film after the protective film is left standing at 80° C. in 85% RH for 1,000 hours). The protective film is used for protecting the information recording layer of the optical disk and the functions of recording and regeneration of the optical disk are not adversely effected.

    摘要： An optical disc-producing sheet 1, which has an adhesive layer 11 having a specific heat capacity after curing of not more than 1.9 J/g·° C. at 80° C. and a protective sheet 12, is laminated onto an information recording layer 3 (a laminate of a reflecting layer 31, a dielectric layer 32, a phase change layer 33 and a dielectric layer 32′) formed on an optical recording medium substrate 2. According to this optical disc, recorded information can be reproduced accurately even in the case that recording/erasure or reproduction of information has been carried out repeatedly.
