Abstract: The present invention relates to an optical film, a backlight unit comprising same, and a liquid crystal display comprising an optical film, and more specifically, to an optical film, a backlight unit comprising same, and a liquid crystal display comprising an optical film for enhancing luminance and external characteristics.

Abstract: The present invention relates to an optical film and an optical display apparatus including the same. The optical film may include a base film and an optical functional layer formed on the base film, wherein at least one of the base film. The optical functional layer may include a luminescent material, and the luminescent material may include at least one of a fluorescent material and a phosphorescent material.

Abstract: An optical film, a backlight unit, and an optical display apparatus, the optical film including a base film, and an optical functional layer on at least one side of the base film, wherein at least one of the base film and the optical functional layer includes rubber.

Abstract: A photocurable resin composition includes an ester (meth)acrylate, an antistatic agent, a silicone additive, an initiator, and at least one UV-curable unsaturated compound. The at least one UV-curable unsaturated compound may include a monofunctional or multifunctional UV-curable monomer, and a (meth)acrylate containing about 10 mol % or more of an ethylene oxide group.

Abstract: The present invention features a method of manufacturing a TWIP type ultra-high strength steel sheet, which can improve the yield strength, tensile strength and elongation rate of the TWIP type ultra-high strength steel sheet by appropriately adjusting the amounts of carbon (C), silicon (Si), manganese (Mn), aluminum (Al), molybdenum (Mo), phosphorus (P) and sulfur (S).

Abstract: A thermal transfer ribbon for forgery prevention comprising: a substrate film; a heat-resistant layer coated on one surface of the substrate film for preventing thermofusibility with a thermal transfer head; one or more than one thermofusible ink layer, or one or more then one thermofusible ink layer and one or more than one protective later coated on the other surface of the substrate just by one layer; and if necessary one or more than one sublimable dye layer, wherein the thermofusible ink layer and/or protective layer contain luminescence, invisible fluorescence or mixture thereof, such that a security function for preventing forgery and alteration is added simultaneously with the printing by using the ribbon equipped with the security function to a printing material in one process.
