Description

[Technical Field]

[0001] The present disclosure relates to blue-violet light absorbing compositions containing phenylacrylonitrile that can be used in fields such as optical films and coatings. [Background technology]

[0002] Visible light is divided into red, orange, yellow, green, indigo, and violet light, with red having the longest wavelength and violet having the shortest. The shorter the wavelength, the higher the energy. According to a research report by German ophthalmologist Dr. RHW Funk, continuous exposure to "inappropriate light" can cause functional damage to the eyes. In particular, primary color lamps and computer screens emit large amounts of high-energy short-wavelength blue-violet light with irregular frequencies. Short-wavelength blue-violet light has high energy and can penetrate the lens to reach the retina, causing photochemical damage and direct or indirect damage to cells in the macular region, leading to macular degeneration in the long term.

[0003] A good blue-violet light absorber must have two basic properties: the ability to filter blue-violet light and bright color. Furthermore, it must be resistant to high-temperature processing and high-temperature environments, as well as have a long lifespan. For high-end applications, the absorbance of a blue-violet light absorber for a specific blue light band gradually decreases with increasing wavelength, and the transmittance of blue light with longer wavelengths must be higher. For example, in the wavelength range from 420 nm to 460 nm, the transmittance of blue light transmitted through optical lenses must gradually increase from 50% to 100% to achieve better vision. Therefore, the conditions for manufacturing a blue-violet light absorber are very strict. Furthermore, blue-violet light absorbers require high-temperature processing when added to plastics or used outdoors at high temperatures. Therefore, resistance to high-temperature processing is a very important requirement. Summary of the Invention [Problem to be solved by the invention]

Conversely, if the layer or film is too thick, the surface may become irregular, the absorption may be non-uniform, or the layer may break or wrinkle during heat treatment.

When applied to a display device, the light-absorbing layer or film is generally disposed in front of the display device. For example, the light-absorbing layer or film is disposed directly on the surface of the display device. When a front panel or electromagnetic screen is disposed in front of the display device, the light-absorbing layer or film can be adhered to the front (outside) or back (display side) of the front panel or electromagnetic screen.

[0100] [Functional Measurement] (thermal stability analysis) Blue-violet light absorbers require high-temperature treatment when added to plastics or when used outdoors at high temperatures. However, typical blue-violet light inhibitors cannot withstand high temperatures. Therefore, high stability at high temperatures is a very important requirement for blue-violet light absorbers. Because the melting point of polycarbonate (PC) is approximately 250-270°C, under high-temperature plastic processing conditions, the blue-violet light absorber exhibits a TGA (thermogravimetric analysis) change of less than 10%, effectively avoiding thermal degradation and decomposition of the blue-violet light absorber due to high temperatures during manufacturing and processing, and preventing loss of blue-violet light absorption function. The thermal stability of the compounds of Examples 1-4 and Comparative Examples 1-3 was measured using a thermogravimetric analyzer (TGA) to determine the temperature at which 10% thermal weight loss occurred. It was found that the higher the temperature, the higher the thermal stability.

[0101] The measurement results are shown in Table 1. The blue-violet light absorbers of Comparative Examples 1 and 3 exhibited a 10% thermal weight loss temperature of 235°C by TGA, and therefore cannot be used for the heat treatment of polycarbonate (PC). The blue-violet light absorber of Comparative Example 2 exhibited a 10% thermal weight loss temperature of 252°C by TGA, and thus had poor thermal stability similar to Comparative Examples 1 and 3. The compound of Example 1 of the present disclosure exhibited a 10% thermal weight loss by TGA even when heated to 292°C, and therefore exhibited excellent thermal stability and could be used for the heat treatment of polycarbonate (PC). Furthermore, the 10% thermal weight loss temperatures by TGA of Examples 2, 3, and 4 were 291°C, 285°C, and 281°C, respectively, which are superior to Comparative Examples 1 to 3 and therefore can be used for the heat treatment of plastics.

[0103] [Analysis of blue-violet light absorption] The wavelength of blue-violet light is 380 nm to 460 nm, and the shorter the wavelength, the higher the energy and the greater the photochemical damage to the retina. Therefore, the greater the absorption of a blue-violet light absorber against short-wavelength blue-violet light in the 380 nm to 420 nm (high energy) wavelength range, the greater the protective effect against short-wavelength blue-violet light. The maximum absorption peaks of the compounds of Examples 1 to 4 and Comparative Examples 1 to 3 were measured using a UV-Vis spectrophotometer.

[0104] (Measurement of maximum absorption peak) The maximum absorption peak (λmax, nm) of the sample was measured using a UV-Vis spectrophotometer (model number: Varian Cary (registered trademark) 50, manufactured by Agilent).

[0105] The results are shown in Table 2. The blue-violet light absorbents of Comparative Examples 1 to 3 had maximum absorption peaks at 418 nm, 421 nm, and 423 nm, respectively, and the maximum absorption peaks were derived from blue-violet light with a long wavelength. The blue-violet light absorbents of Examples 1 to 4 of the present disclosure had maximum absorption peaks at 403 nm, 403 nm, 405 nm, and 395 nm, respectively, and the maximum absorption peaks were derived from blue-violet light with a short wavelength, demonstrating an improved protective effect against blue-violet light with a short wavelength.

[0107] [Measurement of Lifespan of Blue-Violet Light Protection Composition and Blue-Violet Light Protection Film] 30g of CY499 resin containing 1wt% of blue-violet light absorber and 5.5g of HDT-90B hardener were applied to a PET substrate to produce a dried coating with a thickness of 50µm. The coating was then subjected to a weathering test using a xenon lamp (ASTM G155). The transmittance (T%) was measured over time at the shortest wavelength of 1% and the observations were made.

[0108] (Weather resistance test using a xenon lamp) The specimen was placed in a xenon lamp weathering tester (model: Q-SUN Xenon Test Chamber, manufactured by Q-Lab) with a black panel temperature of 60°C and irradiance of 0.5 W / m 2 Weathering tests were conducted under conditions of @340nm.

[0109] Table 3 shows the 1% transmission wavelength of the blue-violet light blocking films containing the blue-violet light absorbent of Comparative Examples 1 to 3 and Examples 1 to 4, and the blue-violet light blocking film containing no blue-violet light absorbent as a negative control.

[0110] The 1% transmittance wavelength of each example compound was measured at 0 hours. Example 1: 442 nm; Example 2: 448 nm; Example 3: 448 nm; Example 4: 435 nm. Examples 1 to 4 absorbed shorter wavelength blue-violet light than Comparative Examples 1 to 3. After 117 hours of irradiation with a xenon lamp, the 1% transmittance wavelengths of Comparative Examples 1 and 2 decreased to 316 nm and 315 nm, respectively, and the blue-violet light absorption function was lost. After 134 hours of irradiation with a xenon lamp, the 1% transmittance wavelength of Comparative Example 3 decreased to 315 nm and the blue-violet light absorption function was lost. In contrast, after 134 hours of irradiation with a xenon lamp, the 1% transmittance wavelengths of Examples 1 to 4 of the present disclosure were 393 nm, 413 nm, 411 nm, and 398 nm, respectively, demonstrating that excellent blue-violet light protection effects were maintained even after long-term irradiation with a xenon lamp.
