Clariant has announced global price increases for selected pigments. The price increases, which come into effect for delivery as of January 15, 2018 or as soon as contracts allow, will affect dioxazine violet and diarylide pigments. Thecompany says prices for PV 23 (dioxazine violet) and PO 34 will be increased by 15 percent. Prices for PY 83 will increase by 14 percent, prices for PY 12, PY 13, PY 14, PY 174 and PY 176 will increase by five percent. The price increases are driven by higher raw material prices for such item as carbazole, hydroquinone, DCB and certain coupling agents. These increases have been triggered by higher environmental, health and safety costs and lack of availability; for example because of the stronger enforcement of environmental and safety regulations in China.
