- HIGH REFRACTIVE MONOMER, RESIN COMPOSITION FOR PRISM SHEET CONTAINING THE SAME AND PRISM SHEET USING THE SAME
-
Disclosed are a high refractive monomer having at least one acryl functional group in a terminal and designed to meet a refractive index more than 1.57, a resin composition for forming the prism sheet capable of controlling refraction, viscosity, hardness, and yellowness by containing the high refractive monomer only or a mixture comprising the same, a prism sheet embodying high refraction and low viscosity of a liquid before curing and having excellent clarity and yellowing resistance by using the resin composition for forming the prism sheet which is made of the optimum mix. According to the present invention, the high luminance prism sheet is provided, thereby reducing the number of the sheet applied to embody the same luminance so as to contribute to slimming down the sheet, enhancing the performance, and saving costs. Therefore, the number of LED lamps used for a backlight unit can be reduced, thereby saving energy.

- METHOD FOR PRODUCING CARBOXYLIC ACID ESTER, ESTERIFICATION AGENT AND RING-OPENING ADDITION CATALYST
-
PROBLEM TO BE SOLVED: To provide a method for producing a carboxylic acid ester using a catalyst compound which is easy to handle and has high activity and to provide an esterification agent and a ring-opening addition catalyst suitably used for the production method. SOLUTION: An imidazole compound having a specific structure is allowed to exist during a reaction when a carboxylic acid ester is produced by reacting (A) at least one electrophilic body selected from the group consisting of at least one hydroxy group-donating compound selected from the group consisting of a phenol compound and alcohol and an epoxy group-donating compound composed of an epoxy compound and (B) at least one nucleophilic body selected from the group consisting of carboxylic acid, a carboxylic acid halide, a carboxylic acid ester and a carboxylic acid anhydride.
