- Selected dyes with Very High Light and Sublimation Fastness
- Mixtures of Anthraquinonw dyes
- Highest batch to batch Quality Control specifications
- Good reproducibility
On-Tone Fading with ITOSPERSE AUTO Disperse Dyes
For the best on tone fading careful dye selection is required and often different shades and depth of shade and fastness test may mean a different dye selection and UV Absorber is needed.
Our best trichromatic recipe would be :
- Itosperse Auto Yellow HLSF
- Itosperse Auto Red A2G
- Itosperse Auto Blue Sun 200%
Using either
- 2-3% Itosorb AF20PS – benzo triazole UV Absorber
- 2-3% Itosorb LJ643 – benzo phenone UV Absorber
To assist in obtaining non metameric matches a 4 colour combination is suggested using the standard trichromat along with either of :
- Itosperse Auto Violet BL 150%
- Itosperse Auto Turq Blue AG
This combination is suitable also for Alkaline dyeing as a solution to Oligomer issues however an alkaline buffer which protects the dye chromopher from hydrolysis is suggested like our Itobuffer PH85 Conc.
