Ink capable of printing fine pattern and printed matter

Abstract

An object of the present invention is to provide an ink which can dispense with complicated and highly expensive steps, as required in the case of using a photosensitive resin composition, such as coating step, exposure step, development step, washing step and drying or heat-treatment step, and can produce printed matter comprising a cured coating film having a fine pattern on a substrate by a simple method of printing the ink by screen printing and then heat-treating it, without generating a large amount of waste solutions, including an alkali solution, accompanying the development or washing. An ink comprising a resin component and a fine filler is disclosed, wherein the edge of a cured coating film obtained through printing by screen printing and then heat treatment has a tilt angle of 15° or more with respect to the printing surface.
