Abstract
Abstract A PROCESS FOR INCREASING THE GLOSS OF PAPER COATING COMPOSITIONS CONTAINING PROTEIN BINDERS IS DISCLOSED. THE PROCESS INVOLVES ADDING A HIGH GLOSS INDUCING MATERIAL TO A BOUND COATING COMPOSITION, COATING A PAPERBOARD STOCK WITH THE COATING COMPOSITION, AND CALENDERING THE COATED PAPERBOARD TO A GLOSS WHICH IS SUBSTANTIALLY HIGHER THAN COATED PAPERBOARD WHICH IS NOT TREATED WITH THE HIGH GLOSS INDUCING MATERIAL. ADDITIONALLY, A GLOSS INDUCING SOLUTION MAY BE SPRAYED ON THE COATING BEFORE CALENDERING OR THE GLOSS INDUCING SOLUTION MAY BE USED SEPARATELY.
