The present invention relates to recording layers of optical data memories,nwhich recording layers are dyes and at least one stabilizerncontain. The at least one stabilizer is an amino derivative, a phenol derivative,na phosphorous acid ester, a thio (dipropionic acid ester), a lead, calcium,nZinc or cadmium salt or an organotin compound. The at least one stabilizernlies in the recording layers in amounts of 0.1 - 70% based onnthe weight of the dyes. The at least one stabilizer becomes onengeneral increase in the durability of optical data storage as well as an increasenthe uniformity and homogeneity of the recording layers. |
