Description

[Technical Field]

[0001] This disclosure relates to a blue-violet light-absorbing composition 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, blue, and violet light, with red light having the longest wavelength and violet light having the shortest wavelength. The shorter the wavelength, the higher the energy. According to a research report by German ophthalmologist Dr. RHW Funk, prolonged exposure to "inappropriate light" can cause functional impairment of 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, penetrates the lens, reaches the retina, causes photochemical damage to the retina, directly or indirectly damages cells in the macula, and in the long term causes macular degeneration.

[0003] Superior blue-violet light absorbers require two basic properties: the ability to filter blue-violet light and a bright color. Furthermore, they must possess high-temperature processing and environmental resistance, as well as a long lifespan. For high-end applications, the absorbance of a blue-violet light absorber for a specific blue light band should gradually decrease with increasing wavelength, with higher transmittance for longer wavelengths. For example, in the 420nm to 460nm wavelength range, the transmittance of blue light passing through an optical lens needs to gradually increase from 50% to 100% to achieve better vision. Therefore, the conditions for manufacturing blue-violet light absorbers are extremely stringent. Additionally, 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 crucial requirement. [Overview of the project] [Problems that the invention aims to solve]

[0005] Blue-violet light-absorbing compositions can be manufactured by processing them into optical films and coatings that absorb light for eye protection, and can also selectively absorb long-wavelength blue light for optimal visual effects of transmitted light. The blue-violet light-absorbing compositions according to this disclosure have the special advantages of being bright in color and being able to absorb blue-violet light, and can be used in technical fields such as plastics, coating materials, inks, display devices, lighting devices, optical films, optical lenses, eyeglasses, textiles, pressure-sensitive adhesives, or sunscreen products.

[0100] [Measurement of function] (thermal stability analysis) When blue-violet light absorbers are added to plastics or used outdoors at high temperatures, high-temperature treatment is necessary. However, general blue-violet light inhibitors cannot withstand high temperatures. Therefore, high stability at high temperatures is a very important requirement for blue-violet light absorbers. Since the melting point of polycarbonate (PC) is approximately 250-270°C, under high-temperature processing conditions for plastics, the TGA (thermogravimetric analysis) change of blue-violet light absorbers is less than 10%, effectively avoiding thermal degradation and decomposition of blue-violet light absorbers due to high temperatures during manufacturing and processing, and preventing the loss of blue-violet light absorption function. The thermal stability of the compounds in Examples 1-4 and Comparative Examples 1-3 was measured at the temperature of the 10% thermogravimetric loss using a thermogravimetric analyzer (TGA), and it was found that higher temperatures indicated higher thermal stability.

[0101] The measurement results are shown in Table 1. The blue-violet light absorbers of Comparative Examples 1 and 3 had a 10% thermal weight loss temperature due to TGA of 235°C, making them unsuitable for heat treatment of polycarbonate (PC). The blue-violet light absorber of Comparative Example 2 had a 10% thermal weight loss temperature due to TGA of 252°C, exhibiting poor thermal stability similar to Comparative Examples 1 and 3. The compound of Example 1 of this disclosure exhibits a 10% thermal weight loss due to TGA even when heated to 292°C, demonstrating excellent thermal stability and suitability for heat treatment of polycarbonate (PC). Furthermore, the 10% thermal weight loss temperatures due to TGA for Examples 2, 3, and 4 were 291°C, 285°C, and 281°C, respectively, which are superior to Comparative Examples 1-3, and suitable for heat treatment of plastics.

[0103] [Analysis of blue-violet light absorption] The wavelength of blue-violet light ranges from 380 nm to 460 nm. Shorter wavelengths have higher energy and cause greater photochemical damage to the retina. Therefore, the greater the absorption of a blue-violet light absorber for blue-violet light with shorter wavelengths (380 nm to 420 nm, which has higher energy), the greater the protective effect against blue-violet light with shorter wavelengths. The maximum absorption peaks of the compounds in Examples 1-4 and Comparative Examples 1-3 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: Varian Cary® 50, manufactured by Agilent).

[0105] The results are shown in Table 2. The blue-violet light absorbers of Comparative Examples 1 to 3 had maximum absorption peaks at 418 nm, 421 nm, and 423 nm, respectively, and these maximum absorption peaks originated from long-wavelength blue-violet light. The blue-violet light absorbers of Examples 1 to 4 of this disclosure had maximum absorption peaks at 403 nm, 403 nm, 405 nm, and 395 nm, respectively, and these maximum absorption peaks originated from short-wavelength blue-violet light, indicating an improved protective effect against short-wavelength blue-violet light.

[0107] [Measurement of lifespan of blue-violet light-blocking composition and blue-violet light-blocking film] 30 g of CY499 resin containing 1 wt% blue-violet light absorber and 5.5 g of HDT-90B curing agent were applied to PET to prepare a dried coating with a thickness of 50 μm. Weather resistance tests were performed using a xenon lamp (ASTM G155). Transmittance (T%) was measured and observed over time at the shortest wavelength at which the transmittance was 1%.

[0108] (Weather resistance test using xenon lamp) The sample was placed in a xenon lamp weathering test chamber (model: Q-SUN Xenon Test Chamber, manufactured by Q-Lab), with a black panel temperature of 60°C and an irradiance of 0.5 W / m². 2 Weather resistance tests were conducted under conditions of @340nm.

[0109] Table 3 shows the 1% transmission wavelengths of the blue-violet light-blocking films containing the blue-violet light absorber in Comparative Examples 1-3 and Examples 1-4, and the negative control blue-violet light-blocking film without the blue-violet light absorber.

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