  • Patent number: 8507076
    Abstract: A base layer is formed on the surface of metal plate, metal pipe, unbaked ceramic sheet, laminated ceramic green sheet, etc., the base layer causing a gelling reaction with inkjet-ink. The base layer improves ink acceptability for low viscosity inks such as inkjet-ink, and prevents oozing, draining, uneven thickness of an ink pattern and a resist pattern. Thus, the present invention enables to use an ink jet process for providing resist patterns for etching, etc., which has to fulfill stringent high precision requirements.
