Abstract
There is disclosed an optically transparent pressure sensitive adhesive sheet for heat transfer image pattern formation comprising an optically transparent film which has a first side constituting a heat transfer image pattern-receiving side and a second side opposite to the first side, an antistatic release sheet provided on the second side of the optically transparent film, via a pressure sensitive adhesive layer. Also disclosed is a first embodiment of an optically transparent decorative pressure sensitive adhesive sheet comprising the optically transparent pressure sensitive adhesive sheet and an image pattern formed by heat transfer method on the first side of the optically transparent film. In a second embodiment of the optically transparent decorative pressure sensitive adhesive sheet, a transparent functional film is laminated on the image pattern formed on the first side of the optically transparent film of the optically transparent pressure sensitive adhesive sheet, via a pressure sensitive adhesive layer. In a third embodiment of the optically transparent decorative pressure sensitive adhesive sheet, the antistatic release sheet is removed from the optically transparent pressure sensitive adhesive sheet having the image pattern on the first side of the optically transparent film, a transparent functional film is laminated on the second side of the optically transparent film, via the pressure sensitive adhesive layer exposed by removing the release sheet. In this embodiment, another pressure sensitive adhesive layer is provided on the side of the transparent functional film which is opposite to the side facing the optically transparent film. In a fourth embodiment of the optically transparent decorative pressure sensitive adhesive sheet, another transparent functional film is laminated on the image pattern formed on the optically transparent film in the third embodiment, via another pressure sensitive adhesive layer.
