ABSTRACT:
An optical recording element in which information can be recorded and read directly afterwards by means of laser light, the element comprising, as a recording medium, a dye, which is not capable of being isomerized due to light, dissolved or dispersed in a binder, the binder comprising a thermally cured organic material composed of non-metallic elements only, and having a cross-linked three-dimensional network structure. The thermally cured binder provides improved stability to repeated read.
