phthalocyanines as colorants in painting
Cyril, thank you. I see a piece of article just missed. Actually now left to do the following:
1. establish whether one and the same place to collect samples.
2. compare the spectra, where we found the phthalocyanine and the spectra of the same land where it did not find, preferably with assigning each band.
It's all will be objective and realistic rig - band in the spectrum either have or not.
We had a situation where in the work we have found acrylic adhesive, and another laboratory has issued opinion (oral), that they result there as the binder oil. Well, we presented the spectra, the photo marked with the coordinates of measurement points, was invited as a judge of a specialist from the Hermitage (technologist). And that was it.
But apart from phthalocyanines as I understand it, the timing had other arguments (the paper and others).
