<p>An ink composition for letterpress reverse printing which comprises a colorant, a dispersant, a binder resin, and a solvent and which is to be used in letterpress reverse printing, wherein the binder resin has a weight-average molecular weight of 1000 to 6000 and contains, in one molecule, on average two or more functional groups of at least one kind selected from the group consisting of epoxy group, hydroxyl group, acid groups, acid anhydride groups, and alkoxysilyl groups; printed matter obtained by letterpress reverse printing using the ink composition; and color filters. Letterpress reverse printing using the ink composition can create fine patterns with high optical density, and can yield durable printed matter.</p> |
