Photo-stability of Acid Dyes, Derivatives of 1-phenyl-3-methylpyrazol-5-one in Polyamide Fibers
acid azo dyes photo-degradation light fastness photo-oxidation photofading
2009/2/10
We have examined the photo-stability of acid dyes, derivatives of 1-phenyl-3-methylpyrazol-5-one, in polyamide fibres, including the relationship between the dye’s structure and photo-stability. The p...
