技术领域
本发明涉及于红外区域内具吸收性的铵盐或二亚铵盐化合物,及含有该化合物的成型产品,特别是光记录介质或红外线屏蔽滤光片。
背景技术
铵盐或二亚铵盐,红外吸收剂,被广泛用于热绝缘胶片或太阳镜。然而,因为该盐在制造过程中容易由光或热引起变质,所以其存在作为染料耐热性和耐光性方面的问题。一种有机染料诸如氰基染料经建议用于光记录介质,特别是一次性写入光盘诸如CD-R和DVD-R的光盘及光卡。由于染料易于被热和光改变,它们具有类似的问题,即记录再生性和搁置稳定性低。已有的任何用于红外线屏蔽滤光片或热屏蔽胶片的染料尚不具备满意的耐热性、耐光性、红外吸收性及可见光透过率。
为了解决这些问题,日本专利特公平6-26028和日本专利特开平1-99885公开了一种加入铵盐或二亚铵盐的方法,但由于未实现满意的耐热性、耐光性,该法仍需改善。有鉴于此,本发明的一个目的就是提供具有优异的耐热性和耐光性,且含有该化合物的产品,特别是光记录介质具有良好的耐光性和耐用性,同时红外线屏蔽滤光片具有优异的耐热性和耐光性。
