Polyethylene films were plasma treated for the purpose of affixing dyeing sites. A methanolic 10% solution of vinyl sulfonic acid (VSA) and polyethylene glycol diacrylate (PEGDA) were used to create a dyeing site-containing resin. Dipping the CF<sub>4</sub> plasma pretreated low density polyethylene (LDPE) films in this solution, the films were then allowed to be penetrated for 22 hours at 75 °C and 0.2 MPa. After drying, the dyeing site-containing resin was fixed on the LDPE film by a further treatment with O<sub>2</sub> plasma. The fixation of the resin to LDPE films was confirmed by Fourier transform infrared spectroscopy (FT-IR) and X-ray photoelectron spectroscopy (XPS). From these analysis, the existence of the spectrum of -C-O and -C=O originating in PEGDA was confirmed. The presence of a sulfonic acid group of VSA was confirmed by observation of the S 2p orbital at 163.8 eV by XPS analysis. Dyeability of the functionalized LDPE films was confirmed by coloring with a cationic dye.
