Study on the Covering Property of White Water-Based Flexo Ink

Abstract:

Covering property (CP) is the most important performance of white ink. In order to research the CP of white water-based flexo ink, this paper studies the component part of ink, which is prepared by changing (a) the variety of both pigments and resins, (b) the ratio of pigment to resin, (c) the variety and the content of dispersants and (d) the variety of film-forming resins. This paper tests the diameter size and coating it onto the surface of the covering power test paper to get their CP data. It has been testified that the dispersion property is the major factor that influences the CP of the white water-based covering ink. The variety of both pigments and resins, the ratio of pigment to resin are the key factors for the CP; the result also proves that different kind of dispersants and contents are also important factors that influence the dispersion property.
