Ink composition for screen printing and method for producing printed matter

Abstract

Provided is an ink composition for screen printing that does not easily allow the generation of a printing defect or a rough surface portion in a printed matter even in the case of forming the printed matter having a thick thickness. An ink composition for screen printing containing (a) a rubber-forming component, (b) a crosslinking agent, (c) a main solvent that dissolves the rubber-forming component and (d) a poor solvent that dissolves in the main solvent but does not dissolve in the rubber-forming component, in which a viscosity (0.1/s) obtained with an E-type viscometer at a temperature of 25° C. is 300 to 50000 Pa·s, a viscosity (10/s) obtained with the E-type viscometer at a temperature of 25° C. is 50 to 1500 Pa·s, and a loss tangent (0.1 rad/s) obtained with the E-type viscometer at a temperature of 25° C. is 10 to 20.
