[0231] Preparation Example 1: Preparation of the first light-absorbing dye

[0232] A dye having the following chemical formula was used as the first light-absorbing dye.

preparation example 1-1

[0234]

[0235] Dimethylformamide (DMF, 20ml) was injected into a 250ml three-neck round bottom flask, and Chemical Formula A1 (10.0g, 0.0247mol) and Chemical Formula B1 (10.7g, 0.0789mol) were put into it. Add potassium carbonate (K 2 CO 3 , 3.4g) and the temperature was raised to 120° C., and reflux was carried out for 3 hours. Ethyl acetate (EA, ethyl acetate, 100 ml) and water were added to the reaction mixture for washing. The solvent was removed to obtain the target compound (chemical formula C1, 15.7 g, yield: 90.13%).

[0238]

[0239] Dimethylformamide (DMF, 20ml) was injected into a 250ml three-necked round bottom flask, and Chemical Formula A1 (10.0g, 0.0247mol) and Chemical Formula B2 (15.5g, 0.1037mol) were put into it. Add potassium carbonate (K 2 CO 3 , 3.4g) and the temperature was raised to 120° C., and reflux was carried out for 6 hours. Ethyl acetate (EA, ethyl acetate, 100 ml) and water were added to the reaction mixture for washing. The solvent was removed to obtain the target compound (chemical formula C2, 18.3 g, yield: 86.00%).

Abstract

Disclosed are: an adhesive sheet for effectively blocking light of an ultraviolet area without deteriorating adhesion and the transmittance of light in a visible light area; and an adhesive composition comprising a binder resin, and a light absorption dye dispersed in the binder resin, thereby enabling light of a wavelength area of 410 nm or less to be effectively blocked and enabling applicability to various types of display devices.

Description

technical field [0001] The present invention relates to an adhesive sheet having an excellent ultraviolet protection function, an adhesive composition, and a display device including the same. Background technique [0002] Recently, a flat panel display (FPD) as a display device has attracted much attention. Such flat panel displays include liquid crystal displays (Liquid Crystal Displays), plasma displays (Plasma Display Panels), organic light emitting display devices (Organic Light Emitting Devices) and other display devices. [0003] Among them, the organic light-emitting display device has a wide viewing angle and a fast response speed, so it can realize high-definition display. In particular, an organic light-emitting display device with a microcavity structure can utilize the resonance effect of light between the upper and lower electrodes to improve output efficiency, and has the advantage of improving the color purity of light. The organic light-emitting display de...
