    摘要： A liquid crystal is dropped on one end portion of a bottom substrate that is coated with a sealing material in an outer peripheral portion. After a top substrate is laid on the bottom substrate, the liquid crystal is expanded from the one end portion of the bottom substrate toward the other end portion. If necessary, an air ejecting opening is formed in the sealing material at a position located in the other end portion of the bottom substrate. The surfaces of the top and bottom substrates may be formed with grooves for accommodating an excessive part of the liquid crystal at positions inside the sealing member. As a result, no air bubbles remain in the liquid crystal even if the charging of the liquid crystal is performed at the atmospheric pressure.

    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： The present invention relates to a multi-layered disc-shaped information recording medium having a plurality of signal recording layers each carrying information signals. In preparing the recording medium, a first substrate obtained on punching a sheet obtained in turn by having a signal recording pattern transcribed on it from a first stamper and by forming a semi-transparent film on a signal surface is bonded to a second substrate obtained on injection molding a synthetic resin material. The second substrate is prepared by having transcribed to it a signal recording pattern formed on a second stamper provided on an injection molding device. A reflective film is formed on a signal surface having the transcribed second substrate. The first and second substrates are bonded together on their signal recording layers by a transparent adherent layer.
