Abstract: In this paper, allyl maleated rosin ester was synthesized by the esterification of maleic rosin and allyl alcohol with catalyst. And then a new waterborne paper-plastic composite adhesive was prepared through the semi-continuous emulsion polymerization method with allyl maleated rosin ester, butyl acrylate, vinyl acetate and acrylic acid as raw materials. The product of esterification was analyzed by IR spectra, and its acid value was determined too. Polymer was analyzed by DSC and IR spectra and its T-style peel strength was determined. The adsorption effect of adhesives to ink was also tested. The results showed that this paper-plastic composite adhesive had good adhesive properties: excellent compatibility with the ink, longer stability period, and low cost.

Abstract: Following with the development and cooperation between digital printing techniques and digital distribution in publishing industry, more and more books will be printed by digital printing equipments, and then the storage stability became one of the focuses in digital printing research field. This study is to investigate the storage resistance property of inkjet presswork. In this paper, based on analyses about factors which influence photoaging phenomenon, a mathematic model which can separate the influence factors and an analytical method were proposed. Then, the experiment under absolutely natural lighting conditions was carried out, and the density decrease, which indicated the color change phenomenon after photoaging, were measured by an X-rite Spectroeye instrument. Through curve-fitting method, an empirical model was derived to demonstrate the rule of ink photoaging fading. Finally, the photoaging property of substrate and ink was analyzed, and the photoaging properties of the inkjet print were generalized. The research methodology and the fading model are of significant reference to the following research about photoaging phenomenon.
