PURPOSE:To obtain the titled material consisting of a compound, which has a specified softening temperature and possesses a vinyl radical, etc., a sensitizer and a coloring agent, and providing the recording surfaces of plain papers, plastics, metal foils and the like with record that is of primary coloring type and is excellent in preservative stability. CONSTITUTION:when a transcription layer is transcribed an recorded to a body to be recroded by heating it by means of a heat-sensitive recording head, the transcription layer consisting of A) a compound which has a softening temperature of 60- 120 deg.C and a vinyl or a (meth) acryl radical that can be polymerized by the irradiation of rays containing ultraviolet rays in the molecule (for example, acenaphthylene, alpha-chloroacrylic acid, etc.), B) a sensitizer, such as, phenanthrene, etc., and C) a coloring agent, is formed on a sheet substrate, preferably at a thickness of 1-10mu. Recording surfaces thermally pressed are irradiated with ultraviolet rays, and hardened by polymerization. EFFECT:Recording surfaces that are excellent in wear proof are obtained. |
