    摘要： 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.

    摘要： A transfer recording medium comprises a support and a transfer recording layer formed thereon capable of charging its transferability when provided with light energy and heat energy. The transfer recording layer comprises at least a colorant and a functional component sensitive to the provision of light energy and heat energy. The functional component comprises at least a photo-initiator and a polymerizing component of a monomer, oligomer or prepolymer having an unsaturated double bond. The polymerizing component has a melting point of 40.degree.-150.degree. C. Because of the inclusion of the polymerizing component which is solid at room temperature, the transfer recording layer has an excellent storability as well as an increased sensitivity contrast to illumination between under heating and under no heating.
