Synthesizing Premetallized Acid Dyes Based on Environmental Considerations
نویسندگان
چکیده
As part of a continuing research program aimed at plausible approaches to synthetic dyes based on toxicological considerations, a group of premetallized iron complexed monoazo dyes were synthesized as potential alternatives to presently used high volume Crand Cocontaining monoazo acid dyes for nylon and wool. This approach takes advantage of the environmentally friendly property of Fe, and draws from the established utility of Fe complexes as brown dyes for certain protein substrates. This investigation has led us to two black Fe complexes having fastness properties comparable to the Cr analogs on both wool and nylon. In addition, we report results from in vitro testing of the Fe complexes for genotoxicity.
