ORANGE FILTER DYE AND FILTER ELEMENT FOR COLOR FILTER ARRAYS

摘要

A metallizable orange azo dye for color filter arrays is disclosed. This dye is comprised of: a 3-pyridinol moiety substituted in the 2-position with a methyl group; and an aryl ring connected to the 6-position of the pyridinol moiety through an azo linkage and substituted in an ortho position relative to such connection with a carboxyl group. A layer containing this metallized dye can be used to form a color filter element.
