Claims11
A light guide comprising:
- a core bar of a transparent material extended in a length direction from a first side to a second side;
- and
- a plurality of reflection parts printed in parallel along with the length direction of the core bar on the outer surface,
- wherein spaces between the reflection parts are the same or decreased from the first side of the core bar toward the second side of the core bar, and
- wherein each of the reflection parts comprises a light spreading ink composition comprising:
- an amount of about 20 to 80 wt % of an acryl-based copolymer resin;
- an amount of about 10 to 70 wt % of a light spreading agent comprising at least one of a silicone bead and an acrylic bead;
- and
- an amount of about 3 to 20 wt % of a light spreading auxiliary agent comprising at least one of titanium dioxide (TiO2) and zinc oxide (ZnO),
- all the wt % are based on the total weight of the light spreading ink composition.
