Abstract
Provided is an ink composition for manufacturing color filters. The ink composition includes an acrylic binder resin obtained by polymerizing the group of monomers containing a compound represented by Formula 1. The ink composition has good chemical resistance and adhesive properties and is used for manufacturing color filters exhibiting a high contrast ratio: (where Ra is —H, or —CH3, and Rb is an alkyl group having 6-30 carbon atoms).
