Abstract
Disclosed herein is a photosensitive resin composition which exhibits proper optical density and hydrophobicity when it is formed into a light-shielding film, and which is useful in preventing the color mixing or position deviation of color ink when the color ink is charged in a region defined by a light-shielding film.
Claims16
A photosensitive resin composition, comprising:
- an alkali-soluble acrylic binder resin;
- and
- a cardo-based binder resin,
- wherein the cardo-based binder resin includes a fluorine functional group;
- wherein when a cured resin film is formed using the composition, the cured resin film has an optical density (OD) of 2.0 or more per unit thickness (2.0 μm), a contact angle of 85°-110° to water, and a contact angle of 35°-50° to 2-ethoxyethanol;
- and
- wherein the alkali-soluble acrylic binder resin is a polymer of a composition including a monomer represented by C(O)OCHCH2(CF2)xCF3 (here, x is an integer of 1-12), and includes 5-50 wt % of fluorine.
