The Effects of the Hollow Plastic Pigment on the Print Properties of High Light Ink_jet Paper

Traditional cast coated glossy photo paper production process due to its characteristics that the water evaporates from non-coated cast side, so the coating speed is slow, ground paper is non-waterproof paper, therefore the paper products are easy to transmutative, as the cast shows that the formation of dense coatings membrane, the lower ink absorption. To solve such the problems, a novel porous ink receiving layer constituted by a litter amount of a hydrophilic binder(PVA) and a cross-linking agent, a large amount of inorganic pigment(SiO2) and a hollow structural plastic pigment. In this paper, the effects of the hollow structural plastic pigment rheological properties of the color and the printing and preservation properties of ink jet paper were investigated. Because of the thermoplasticity of the plastic pigment the calendering and dry technology were also studied. From the viewpoint of water-fastness and preventing the penetration of binder, the resin coated paper(being so-called RC paper) is selected as the substrate.
