摘要： Provided is a resist composition for pattern printing containing a resin (A) component that contains a combination of at least two or more types of amino group-containing resins each containing an amino group of different amine numbers respectively, the entire resin (A) component having an amine number of 1.5 to 10.0, a compound (B) component that generates an amine by means of moisture and/or light, a thickener (C) component, and a diluent (D) component. The resist composition has high resistance to an alkaline etchant, can be easily peeled off by an aqueous acid solution, and enables a protective pattern to be formed by printing.
