PURPOSE:To eliminate the influence of an adhesive agent on a recording material, to prevent the deformation of substrates and to reduce curing time by using an adhesive agent contg. a resin curable by UV rays having >=250 deg.C b.p. as the above-mentioned adhesive agent. CONSTITUTION:This information recording medium has the sealing construction in disposing a pair of the substrates having the recording layer on at least one side of two disk-shaped substrates in such a manner that the recording layer faces the inside and pasting the substrates via or without via a space by the adhesive agent. The adhesive agent is the resin curable by UV rays having >=250 deg.C b.p. The influence of the resin curable by UV rays to the recording material occurs in the evaporation of the uncured part of said resin and therefore the resin having the high b.p. among the resisns curable by UV rays is used alone or in combination or as an essential component; said resin is preferably used in conjunction with a photopolymn. initiator. The photopolymn. initiator is used in a 0.1-20pts.wt. range by 100pts.wt. resin, more preferably in a 1-10pts. range. |
