PURPOSE: Provided are a printing ink resist composition, a method of forming a resist film and a method of producing a substrate using the same, of which process is simple, of which process management is easy and which can form a fine pattern. CONSTITUTION: The printing ink resist composition containing a phenol resin as the main resin component further contains a thickening agent. The method of forming a resist film comprises a step (1) of conducting a screen printing, by using a printing ink resist composition which contains a phenol resin as the main resin component and further contains a thickening agent, on the surface of a substrate having a metal layer on its surface to form a resist film having a desired pattern; a step (2) of performing drying on the resist film formed on the substrate as occasion demands; and a step (3) of removing the metal layer at portions on which the resist film is not formed by a development using an etchant. The method of producing a substrate having a metal layer pattern comprises a step (1) of conducting a screen printing, by using a printing ink resist composition which contains a phenol resin as the main resin component and further contains a thickening agent, on the surface of a substrate having a metal layer on its surface to form a resist film having a desired pattern; a step (2) of performing drying on the resist film formed on the substrate as occasion demands; a step (3) of removing the metal layer at portions on which the resist film is not formed by a development using an etchant; and a step (4) of removing the resist film after the step (3).
