Abstract
In order to investigate the influence of coating layer characteristics on the dynamic permeability and printing of ink-jet paper, coating was prepared by the precipitated calcium carbonate (PCC) and white latex used as bottom coating (recipe label:A,B),and coating formula was made by silica (SiO2) and polyvinyl alcohol used as surface coating (recipe label:a,b,c).Then paper were coated respectively on single bottom, single surface and multilayer. Then the dynamic permeability and printing of ink-jet paper were analyzed systematically. The results showed that whether single layer or multilayer, the values of Ct, Ci were minimum when the ration of pigment and adhesive was 70:30, because the hole diameter of the coating layer was smallest, and the absorption was strongest, so the dynamic permeability was best, and the ability of ink absorption was best, color density and tone reproducibility were best. It concluded that when the proportion of SiO2 and PVA was 70:30, the dynamic permeability and printing ability of ink-jet paper were relative better.
