Abstract

In this study, in order to investigate the influence of insolubilizer on the double coating structure, we carried out basic research related to the double coating formulation with four insolubilizers having various chemical types such as amino aldehyde, glyoxal and two metallic salts. It was found that although the four insolubilizers showed similar results on optical and surface properties of the coated papers, they gave different results in the printabilities of the coated papers since coating structure was significantly influenced by different reacting mechanism of the insolubilizers. Three of the insolubilizers (glyoxal, two metallic salts) showed better results than amino aldehyde type one when they were applied to top coating formulation. Metallic salts type insolubilizers showed good results in the print gloss when it was applied to top coating formulation. It was believed that amino aldehyde type insolubilizer applied top coating formulation showed good both of dry-pick and wet-pick strength.
