Zusammenfassung:PURPOSE:To reuse paper which is once used for copy by using a synthetic paper or paper coated with a synthetic resin as a copy paper, and erasing letters or figures copied on this paper with a solvent. CONSTITUTION:A synthetic paper is used for copy. Then the paper used for copy is brought into contact with lacquer thinner as a solvent to dissolve the toner. Then the dissolved toner and the thinner are removed. Namely, a synthetic paper or paper coated with synthetic resin is used as a copy paper, and letters or figures copied on this copy paper are erased with a solvent. Thereby, the paper once used for copy can be reused, which saves energy and resources.
