摘要
The Paper studied the effects of pigments and base paper on binder migration and affected factors. The z-direction distribution of the coating binder which was tagged with Br in coating layer and its concentration in coating surface were examined quantitatively by using SEM-EDXA and ESCA analysis. The results showed that the increase of the ratio of calcium carbonate in the pigment content, coating surface binder concentration increased, and coating surface binder concentration increased with the increase of particle size of pigments. The result also indicated to small base paper absorbency, coating surface has high binder migration level, the coating layer bottom (base paper direction) has low binder concentration. To high absorbency base paper, the opposite is true.
