ADHESIVE COMPOSITION FOR SURFACE PROTECTIVE FILM AND SURFACE PROTECTIVE FILM USING THE SAME

摘要

A pressure sensitive adhesive composition for a surface protective film, and a surface protective film using the composition are provided to improve antistatic property and to prevent the generation of bur in case of cutting a surface protective film. A pressure sensitive adhesive composition comprises 1-5 parts by weight of an ion complex polymer antistatic agent based on 100 parts by weight of an acrylic resin, wherein the ion complex polymer antistatic agent is prepared by reacting at least one cationic metal salt selected from LiPF6, LiBF4, LiSbF6, LiClO4, LiCF3SO3, LiAsF6, LiC(CF3SO3)3, LiN(CF3SO3)2, LiNH2, LiN(C2H5)2, LiNH2, LiN(C2H5)2, LiI, LiBr, LiCl, LiF, NaPF6, NaClO4, NaI, NaSCN, KSCN, KPF6 and KClO4 with a cation conductive organic compound selected from propylene carbonate, ethylene glycol and dimethylformamide and an anion conductive organic compound selected from trilauryl phosphate, trichloromethyl ester and dimethylsulfoxide in turn.
