摘要

本研究探討接著劑對塗料液性質之影響，瞭解不同接著劑用量以及少量陽性澱粉取代部分酯化澱粉接著劑時，對輕量塗佈紙塗層結構和塗佈紙性質之影響，進一步分析在最適接著劑用量下，陽性澱粉對輕量塗佈紙性質之作用。
結果顯示，接著劑用量13%時，以0.5%之陽性澱粉取代部分磷酸酯化澱粉，所得塗佈層較緻密；不需添加耐水化劑，且在室溫下壓光即可獲致最佳的IGT乾強和濕強性質，而其不透明度不受影響，此為本研究之重要發現。

The main objectives of this study was to elucidate the effect of binder dosages, and the addition of cationic starch in the coating colors on the coating layer structure and the paper properties. The effect of binders on the properties of the coating color was also examined.
The results showed that at 13% binder’s level, the addition of 0.5% cationic starch to partially replace the phosphate starch produced a denser coating layer and resulted in the best IGT dry and wet pickings resistence, without losing the opacity of the coated products. No glyoxal was used as an insolubilizer in the coating colors for the said application. The advantages of adding small amount cationic starch in the colors on the coated paper properties were thus confirmed in this study.
