1. Obtained by synthesizing blue light. In recent years, these type-A devices have become increasingly popular, and as a result, there is a demand for clearer images. However, commonly used phosphors have a high proportion of the main peak in the emission spectrum and have poor color purity, making it difficult to reproduce faithful colors. For example, rare earth Y2O3:Eu or Gdz are used as red, green, and blue light emitters, respectively.
When O2S: Tb and sulfide-based ZnS: AH are used, the main peaks of luminescence are 82Qnm and 55, respectively.
0nm and 450nm, whereas sub-peaks occur around 560~@00nm and 1330nm for red color, and 480~490nm and 580~590nm for green color.

択吸収する効果が少ない、又。Conventionally, a method has been used to disperse neodymium in the cathode ray tube panel in order to absorb other subpeaks and produce a clear image. This results in the neodymium being dispersed up to 500 nm, which poses a problem in terms of product cost.Another method is to disperse a neodymium compound that absorbs the wavelength corresponding to the subpeak into a synthetic resin, and coat the display surface with this resin. Alternatively, a method is known in which the neodymium compound is installed in front of the display screen.However, if an inorganic compound is selected as the neodymium compound, the absorption characteristics are not so pronounced and the effect of selectively absorbing subpeaks is small.

を特徴とする光選択吸収性合成樹脂板が提供される。As a result of seed planting studies, the inventors of the present invention have found that when neodymium carboxylate is blended with a transparent synthetic resin in the visible region, this resin absorbs ultraviolet rays (wavelengths less than 400 nm), and It has the property of selectively absorbing wavelength bands of ~530nm and 570~600nm, and also exhibits good transparency for other wavelengths in the visible region, significantly reducing the effects of subpeaks and improving the color cathode ray tube display surface. The present invention is based on the above knowledge, and according to the present invention, neodymium carboxylate is added to a transparent synthetic resin in the visible region as neodymium. A light-selective absorptive synthetic resin board is provided, characterized in that it contains 25 to 5.00% by weight.

The amount of these neodymium carboxylates added to the synthetic resin is preferably 0.25 to 5.00% by weight2 as neodymium.
．． If the weight exceeds 0.00 weight 2, the resin will become cloudy, and if the weight exceeds 0.25 weight, it will not be effective in absorbing sub-peaks, and unless the thickness of the plate is unrealistic, sufficient absorption effect will not be obtained, making it difficult for practical use.

As shown in the Examples and Comparative Examples below, compared to those added with other neodymium compounds, it has a greater effect of selectively absorbing light with wavelengths of 500 to 530 nm and 570 to 1300 nm. It has an excellent effect of absorbing sub-peaks and making images clearer. This is thought to be because neodymium carboxylate is compatible with the synthetic resin, and therefore has much better selective absorption than when other inorganic or organic compounds of neodymium are added.
