Abstract
An optical information recording medium comprising a glass base, a primer coating layer formed on the glass base and a recording layer formed on the primer coating layer is disclosed. The optical information recording medium is characterized in that the primer coating layer comprises a linear acrylic resin having as a repeating unit an atomic group represented by the following formula (1): ##STR1## wherein R.sup.1 is a hydrogen atom or a methyl group and R.sup.2 is an alkyl group having 1 to 4 carbon atoms. A coupling agent may be interposed between the primer coating layer and the recording layer.
