EC No. 304-811-3
Chemical Family Monoazo
Compare our solvent yellow 146 we produce and Ciba Orasol yellow 4GN:
In terms of dissolution:both have a good solubility in organic solvents and generally can meet customer requirements.
Strength: Ciba 4GN has a much better tinting strength than our Solvent Yellow 146.Please see the spectrum.
Make the Ciba 4GN as standard sample,we have two batches of solvent yellow 146 samples for comparison,one is 150301,another is 150302.(Note:3#:150301 is the sample we supply before,2#:is the improved sample,1#:is Ciba 4GN sample)We can see from the chart,the intensity of 2# is 82.58% of standard sample,3# is 92.67% of standard sample.From the spectral analysis,we can see that our intensity still has a distance when comparing with Ciba 4GN and still need to improve.
Appearance:both are powder,please see the picture at right side.There are obvious difference on appearance,ours are bright yellow but Ciba 4GN are dark yellow.
According to our customers feedback,the other using effect is relatively close but the strength still need to improve.
