PVP used in ink

As printed materials such as stamps and printer ribbons, the inkjet ink used for printing needs to be used for a long time. Therefore, pigments with excellent lightfastness and water resistance are required as the coloring components of the ink. It is necessary that the main components of the pigment micro-particles can be evenly dispersed to avoid agglomeration caused by poor dispersion. If the inkjet ink has poor performance in terms of dispersion stability and viscosity, This will make the printed portrait and handwriting unsatisfactory. In addition, as the long-term use of the inkjet printing equipment may cause local temperature rise, the ink is also required to have a certain degree of temperature stability.
The ink for ballpoint pens and the addition of PP-K30 in the ink play a role in protecting the colloid, thickening and increasing viscosity, making the writing smooth, without overflow or fading. It can also reduce the wear of the balls and extend their service life.
