摘　　要：研究了染料及其与其他湿部化学品的相互作用对纸张光学性能的影响,研究表明,紫色染料的增白效果最好;染料和荧光增白剂之间有一定的协同效应,能够更好地改善纸张的CIE白度和降低b*值;填料会吸附部分染料从而降低染料的效率。The behavior of the dye at wet end and its effect on the paper optical properties were studied in this paper. The results showed that the violet pigment dyes have the highest whitening efficiency. Some synergism between dyes and OBA （Optical Brighten Agent） can improve the CIE whiteness and decrease the b^＊ value of the paper. PCC filler will absorb some dyes when they mix together, which will lower down the effectiveness of the dyes.
