油墨用浅色松香酚醛树脂2116~＃、2118~＃的研制

PREPARATION OF LIGHT-COLORED ROSIN PHENOLIC RESINS(2116￣#、2118￣#)FOR PRINTEING INK

本工作对油墨用松香酚醛树脂的生产工艺进行了重大的改进，所选用的新催化剂、浅色剂使产品颜色比中国企业标准浅３级，比国外同类产品浅２～４级。新工艺反应条件温和、保险系数较高，降低了能耗、物耗，具有较好的经济效益。

This work totally improved the process of producing rosin phenolic resin(2116￣#,2118￣#)for print-ing ink.The color of the products obtained by using new kind of catalyst and decolorizing agent is 3grades lightet than that required by China enterprise's standard and 2～4 grades lighter than that of the same kinds of products from abroad.The new process is simpler,easier to control,and cunsumming less energy and mate-rials. Consequently, better profit can be expected.
