ABSTRACT:
A recording medium has a recording layer comprising image-forming elements (A), (B) and (C) containing at least a compound having unsaturated double bond and a photopolymerization initiator. The photopolymerization initiator in the element (A) is a compound represented by the following formula (I): ##STR1## (wherein Ar.sub.1 and Ar.sub.2 are ech aromatic ring or heterocyclis ring). The photopolymerization initiator in the element (B) has an absorption maximum in a wavelength region of 360 to 430 nm. The photopolymerization initiator in the element (C) has an absorption maximum in a wavelength region of 430 nm or longer. The recording medium is suitably used as a transfer recording medium in a recording apparatus which includes heating means and light irradiating means to provide the recording layer with heat energy and photoenergy to change the transfer characteristic of the recording layer. The light irradiating means includes a phosphor of thallium-activated calcium phosphate or thallium-activated calcium zinc phosphate, a phosphor having a fluorescent peak wavelength of 360 to 430 nm and a phosphor having a fluorescent peak wavelength of 430 nm or longer, and a light source for exciting the phosphors.
