Abstract
Abstract In order to improve its printability the effects of pigment sizing on printability and coating structure of decorative base paper were investigated. Silica, styrene-acrylic emulsion (SAE) and cationic starch were used to prepare the pigment sizing solution. After been pigment sized, the physical performances, printing properties and coating structure of the paper were determined. Pigment sizing had a more obvious effect on the physical properties, printability and coating structure. The tensile strength was increased by 26.99 %, the print-surf roughness was decreased by 17.98 %, the water absorption height was increased by 8.51 %. The color density was improved, the percentage of dots loss decreased by 21.33 %, the roundness of dots increased by 43.33 % and thus better printing effect was achieved. The water receptivity and absorption of decorative base paper could be improved by pigment sizing under the appropriate binder-to-pigment ratio. SEM and three-dimensional image showed that silica/cationic starch/SAE had filled the pores of paper and formed an uniform coating structure. Considering the improvement of the physical properties, printability and coating structure, the best ratio of binder-to-pigment was identified as 70:30.
