  • Publication number: 20030209160
    Abstract: A cast coated printing sheet providing high paper gloss and smoothness, desirable printing performance characteristics, and enhanced printed product attributes. The cast coated sheet comprises a substrate and a brushed coating layer comprising (a) a pigment, (b) a functionally effective amount of latex such that a dried unbrushed layer of the coating will not adhere sufficiently to the casting surface to allow the unbrushed layer to be cast, and (c) a functionally effective amount of brushing agent such that damage to the coating layer surface during brushing is minimized. The invention further provides methods for manufacturing such cast coated printing sheets.
