DRYING METHOD OF PRINTED MATTER AND PRINTED MATTER MANUFACTURED BY THE METHOD

摘要

PROBLEM TO BE SOLVED: To provide a method of efficiently drying and removing a solvent penetrated into a synthetic resin base material in case of carrying out printing on the synthetic resin base material having insufficient heat resistance with ink including the solvent and to provide printed matter manufactured by the method.;SOLUTION: A manufacturing method of the printed matter includes the step of forming a printing layer with the ink including the solvent on the thermoplastic synthetic resin base material, the step of primarily drying the solvent in the range that the temperature of the base material becomes lower than the glass transition temperature of the thermoplastic synthetic resin used for the base material, and the step of secondarily drying the solvent in the range that the temperature of the base material in vacuum is lower than the glass transition temperature of the thermoplastic synthetic resin used for the base material.;COPYRIGHT: (C)2010,JPO&INPIT
