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.
Claims22
A combination of a base layer formed on a surface of an object to be printed and an ink used for printing on the base layer,
- wherein the base layer and the ink satisfy one of the following two conditions:
- (A) the ink includes an organic compound,
- the base layer includes at least 0.01 weight % of a component, which reacts with the organic compound included in the ink to cause gelation after the ink is printed on the base layer, and
- the base layer comprises organic material that is burnt off by baking at a temperature not lower than 300° C.
- (B) the base layer includes an organic compound,
- the ink includes at least 0.01 weight % of a component, which reacts with the organic compound included in the base layer to cause gelation after the ink is printed on the base layer, and
- the ink comprises organic material that is burnt off by baking at a temperature not lower than 300° C.
