Functional Pigments Impact on the Performance of Coated Paper

Elect Titanium Dioxide, PCC, nanometer calcium carbonate and hollow plastic pigment as the functional pigment. Add them to the paint as the total of ten percent of pigment's solid content. Use C65 and C95 to do the contrast experiment of the two groups of functional pigments. Via measurement of brightness, smoothness and gloss of coated paper, I research functional pigments impacting on the performance of coated paper. The results show that selecting high-brightness of the functional pigment can increase the brightness of coated paper. PCC, nanometer calcium carbonate and hollow plastic pigment can make the coated paper have higher brightness. Hollow plastic pigment as the functional pigment can make the coated paper have higher smoothness and gloss. With the same functional pigment, coated paper will have the smoothness and gloss higher by C95 than by C65.
