[0137] Example 1 and Example 2 and Comparative Examples 1 to 4: Preparation of Optical Sheets
example 1
[0139] A photocurable resin composition comprising: 70% by weight of acrylate resin (TBP102, Hannong Chemical Co., Ltd. Co., Ltd.), 5% by weight of phenoxybenzyl acrylate, 7% by weight of bisphenol F acrylate, 10% by weight of ethoxylated sulfur diphenyl diacrylate, 1% by weight of ester acrylate (ECX 5031, Corning Co., Ltd.), 2% by weight of antistatic agent (HR-E, Nano Chemical Technology Co., Ltd.), 1% by weight of silicon additive (UV-3530, BYK company) and 4% by weight of initiator agent (Irgacure 184, Irgacure TPO, Ciba Chemical Co., Ltd.). When one surface of the base film (polyethylene terephthalate film, Toyobo Co., Ltd.) of Table 1 was brought into contact with the composition layer on the mold, the coated composition was cured by irradiating with ultraviolet light to form a coating. Floor. Subsequently, the coating layer bonded to the base film was separated from the mold, thereby preparing an optical sheet having a light collection pattern layer on one surface of...
example 2
[0142] An optical sheet was prepared in the same manner as in Example 1, except that the height, pitch, and apex angle of the unit prisms constituting the light-collecting pattern layer were changed as listed in Table 1.
