Nippon Keiko Kagaku Co. Ltd., Japan (NKK) is a longstanding manufacturer of fine particle size high intensity daylight fluorescent pigment dispersions especially for quality marker and gel pen ink formulations.
We have been working to develop sales in Europe for the past 5 years. The development of the formaldehyde-free water-based dispersions has seen good acceptance from the market which is demanding more eco-friendly products.
Lumikol A-200 series of daylight fluorescent pigment dispersions are specifically designed for the flexographic ink maker. The advantages of this range of colourants are that they are fine average particle size (approx. 0.4 micron), have a narrow particle size range (+/- 0.1 micron), are formaldehyde free and have high pigment concentration (above 50%). They transfer easily and offer excellent daylight fluorescent colours.
Lumikol NKW-3200 series – for felt marker pens with a very fine particle size (average 0.1 micron).
Lumikol NKW-2200 series – for metallic nib gel pens with higher viscosity and strong colours.
