  • Low temperature baking adapted resist ink
    Patent number: 10429733
    Abstract: The present invention has an object to provide a resist ink adaptable to low temperature baking that has both of an adhesiveness to the metal foil for constituting a circuit and an acidic etching resistance even at a low oven temperature. The present invention can overcome a negative effect of decreased baking temperature, that is, reduced adhesiveness of a printed coat to a substrate metal foil and reduced acidic etching resistance in the step of acidic etching. A resist ink is adaptable to low temperature baking containing a polyester resin, a titanium oxide, and an organic silicon compound as essential components.
