Abstract
The present invention provides an optical recording medium having on a substrate a recording layer containing an organic coloring matter and a record-assisting layer which is formed out of an elastic polymer cured by a radical reaction. So that radicals generated in the record-assisting layer may be inactivated, a radical scavenger is given to the recording layer, or a radical-scavenging layer is provided between the recording layer and the record-assisting layer.
