PROBLEM TO BE SOLVED: To provide a reversible heat sensitive recording body, in which light resistance, durability, transparency, hard coating properties and antifoulancy are improved, by a method wherein the surface of the reversible heat sensitive recording body is covered by a polymer type coating agent composition including an ultraviolet absorbing unit and a silicon macromer unit. SOLUTION: A polymer ultraviolet absorbing polymer layer 6, which is obtained by copolymerizing a monomer including a silicon macromere (D) consisting of at least one kind of ultraviolet absorbing monomer (A) selected from the group consisting of benzophenon-based ultraviolet absorbing monomers and benzotriazole-based ultraviolet absorbing monomers, a copolymerizable vinyl monomer (B) and a functional group-containing copolymerizable vinyl monomer (C) as a hard coating component, is formed on the outside surface of a reversible heat sensitive recording layer 5 or a polymeric ultraviolet absorbing polymer is mixed in the recording layer 5. |
