Influence of Coating Binder Migration on Coated Paper Optical Properties

Article Preview

Abstract:

The coating binder migration and concentration in z-direction of coating layer especially in coating surface influence coated paper optical properties. The results showed that with the increase of coating surface binder migration, the calendaring gloss decreases, the printing gloss and the printing optical density increases. The calendaring gloss and printing gloss, compared to the influence of binder distribution in coating layer,seemed more subject to coating surface binder concentration. Binder in the coating surface concentration and distribution in z-direction almost did not affect the whiteness of coated paper.
