A recording medium comprising a substrate and a transfer recording layer containing a photo-initiator comprising camphorquinone and a coumarin derivative. Such photo-initiator aids in realizing high sensitivity without lowering storage stability of the recording medium. The transfer recording layer

A recording medium comprising a substrate and a transfer recording layer containing a photo-initiator comprising camphorquinone and a coumarin derivative. Such photo-initiator aids in realizing high sensitivity without lowering storage stability of the recording medium. The transfer recording layer causes a change in transfer characteristic when provided with light energy and heat energy, at least one of which is applied imagewise, to provide a transferable portion therein. The transferable portion is then transferred to a transfer-receiving medium such as plain paper to form a transferred image thereon.
