Abstract

A study of the photodestruction of metal-containing organic dyes that absorb light in the near-IR region of the spectrum has been carried out. The light fastness in the polymer matrix of both individual dyes and their binary mixtures with monoazo dyes of the pyrazolone series has been studied. The study was performed during 10 h of insolation. The degree of decomposition of the dye under the action of light was determined from the decrease in its optical density at the analytical wavelength in the electronic absorption spectra. A light stabilizing effect on the IR absorbers of pyrazolone azo dyes containing a nitro group has been shown. Recommendations are given on the use of the investigated metal-containing and pyrazolone dyes in the development of light-stable polymer optical filters.

吡唑啉酮偶氮染料对聚合物薄膜中红外吸收剂的光稳定作用

摘要

对吸收光谱近红外区域光的含金属有机染料的光破坏进行了研究。研究了单独染料及其与吡唑啉酮系列单偶氮染料的二元混合物在聚合物基质中的耐光性。该研究是在 10 小时的日光下进行的。染料在光作用下的分解程度由其在电子吸收光谱中分析波长处的光密度降低来确定。已经显示出对含有硝基的吡唑啉酮偶氮染料的 IR 吸收剂的光稳定作用。建议使用所研究的含金属和吡唑啉酮染料开发光稳定聚合物滤光片。
