Abstract
Abstract The invention relates to a transferable paint film which has a silicone layer serving as a separating layer, said silicone layer being highly cross-linked and of the alkenyl-group-containing polyaddition type and including an adhesive layer as well as a paint layer. The paint layer can be peeled off along with the adhesive layer by hand, and stuck on a surface to be treated with paint.
