Abstract
Abstract A dry transfer material is provided on a transparent polyalkylene which is coated with a varnish layer, printing ink layers forming an image mirror of the desired image, a second varnish layer and an adhesive layer, said adhesive layer extending beyond the contours of the varnish and image layers, wherein the adhesive layer contains a primer for said polyalkylene due to which the adhesion of the adhesive to the transparent substrate is greater than the cohesion in the adhesive layer so that during transfer of the image the adhesive layer breaks around the contours of the varnish.
