Abstract
The present invention relates to a light-diffusing ink composition and to a light guide panel and display unit using same, wherein the light-diffusing ink composition comprises: an ink binder made of one or more selected from a group consisting of acrylic resin and polyvinyl chloride (PVC) copolymer; polymethylmethacrylate (PMMA) particles for forming a crystal optical pattern; and a solvent for ink. According to the present invention, light from a light source is converted into a crystal optical pattern and outputted, thus producing aesthetic and sensuous light, and lighting with an aesthetic design can be achieved by means of the light guide panel using the composition.

A light-diffusing ink composition comprising:
- an ink binder including at least one selected from the group consisting of an acrylic resin having an index of refraction of 1.49 and a polyvinyl chloride (PVC) copolymer having an index of refraction of 1.48;
- polymethyl methacrylate (PMMA) particles for forming a crystal light pattern;
- and
- a solvent for ink including at least one selected from the group consisting of ketones, esters, ethers, hydrocarbons, and glycol ether organic solvents,
- wherein the PMMA particles have an index of refraction of 1.49 and comprise PMMA beads having an average particle size of 13 μm to 30 μm,
- wherein the composition comprises 100 parts by weight to 590 parts by weight of the ink binder and 160 parts by weight to 1000 parts by weight of the solvent for ink, based on 100 parts by weight of the PMMA particles.
