Abstract
A sheet for printing, which comprises an ink-receiving layer comprising a fluoropolymer film, optionally having property to absorb or scatter ultraviolet rays; an ink comprising a fluoropolymer and a colorant; and a printed sheet comprising the sheet for printing and information comprising the ink formed on the ink-receiving layer of the sheet by thermal transfer printing. With the sheet for printing and the ink, it is possible to form a printed sheet having so high weatherability that the ink information, even upon outdoor weathering, does not disappear and retains satisfactory readability over long period of time without the necessity of forming a coating layer thereon, by imparting ink information in situ, etc. by thermal transfer printing according to circumstances. Ink information can be imparted according to circumstances even with a commercial thermal transfer printer, and the ink information formed is excellent in fixability and weatherability because the ink, during the thermal transfer, was satisfactorily fused and contact-bonded to the ink-receiving layer through the fluoropolymers.
