PURPOSE:To improve strength of a strippable layer and to prevent tackiness of the surface and sticking of a dye or pigment to the surface of a plastic film support by incorporating an antistatic agent solid at normal temperature in the strippable layer. CONSTITUTION:The strippable layer contains the antistatic agent solid at normal temperature, such as a solid surfactant and an organoboron compound, and as the practicable surfactant, glycerin stearate is preferable because it does not so much affect the adhesiveness of the strippable layer. Its suitable adhesiveness and its moderate strippability can be maintained by adjusting a proportion of glycerin mono-, di-, and tri-stearates. The antistatic agent is added, preferably, in an amount of 0.5-10wt% of the total solid of the strippable layer. |
