摘　　要：研制出一种新型高效分散剂,该分散剂由水杨酸、多聚甲醛和十八胺通过Mannich反应生成。该分散剂通过空间位阻作用使颜料分散性能得到充分发挥,油墨的着色力得到明显提高。A new type of highly effective dispersant was prepared applied salicylic acid, paraformaldehyde and octadecylamine as the starting materials via Mannieh reaction. The dispersant could improve the dispersibility of the pigment and the tint strength had been enhanced.
