摘要

The present invention is a bonding anchor coating agent and a laminated film having an anchor coating layer which provides a high anti-static performance on a film surface without having to mix the anti-static agent into the basic material of the film. The bonding anchor coating agent contains polyethylene imine and a bridge formation polymer having the ability to prevent electrostatic induction. The laminated film contains the anchor coating agent in the basic material of the film.
