Protective agent for printed matter and protection layer forming method |
摘要 |
A protective agent for protecting a print formed on a printing object comprises a high-volatile organic solvent as a dispersion medium and non-water family high polymer emulsion liquid including synthetic resin particles as a dispersoid. This protective agent is sprayed onto a print formed on a printing object by a spray method and then dried. For example, an oil-based first print layer 2 is formed on a surface of an information record member 1, an oil-based second print layer 3 is formed on at least a part of the upper surface of the first print layer 2, and the aforementioned protective agent is applied on the upper surface of the second print layer 3 and dried to form a protective layer 4. Thus, the print will not disappeared even if a hands touches or water is adhered, and no bad influence will be given to the substrate material since the protective agent is excellent in quick-drying property.
