Problems solved by technology

[0005] Conventional LCDs are provided with a color conversion film containing dyes for coloring, in which many inorganic fluorescent substances have been used as dyes, but since inorganic fluorescent substances have a narrow color gamut, there is a problem that the color conversion rate decreases, and in order to improve This problem has recently been attempted using organic fluorescent substances instead of inorganic fluorescent substances.
[0006] However, most organic fluorescent substances are easily oxidized by external factors such as moisture to cause a photobleaching phenomenon, and thus have a problem that the optical characteristics of the color conversion film deteriorate

Embodiment 1

[0067] (1) Preparation of resin composition

[0068] Into a sealable 500 mL reaction vessel were introduced 74.5 parts by weight of dimethylformamide (DMF, SigmaAldrich), 0.5 parts by weight of BODIPY-FL (Thermo Fisher) and 25 parts by weight of polymethylmethacrylate and polymethylmethacrylate Acrylic acid was mixed at a weight ratio of 5:5 and stirred at room temperature for about 1 hour to prepare a homogeneous resin composition.

[0069] (2) Manufacture of color conversion film

[0070] The resin composition prepared above was applied to the release surface of the release PET, and dried (5 atm) in an oven at 130° C. for 3 minutes to manufacture a color conversion film including a color conversion layer with a thickness of 50 μm. For the use of ultraviolet light at 2J / cm in a nitrogen atmosphere 2 (Based on 100mW / cm in area A 2 ) to measure physical properties by irradiating a sample of the fabricated film.

Description

technical field [0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2017-0062427 filed on May 19, 2017, the disclosure of which is incorporated herein by reference in its entirety. technical field [0003] The present invention relates to a resin composition, a reliability evaluation method thereof, and a color conversion film comprising the same. Background technique [0004] TVs are becoming high image quality, thinner and more advanced, and larger in size. OLED TVs with high performance and high picture quality still have issues of price competitiveness, and thus the market has not really opened up yet. So, keep trying to similarly secure the benefits of OLED and LCD. [0005] Conventional LCDs are provided with a color conversion film containing dyes for coloring, in which many inorganic fluorescent substances have been used as dyes, but since inorganic fluorescent substances have a narro...
