IMAGING PLASTICS ARTICLES

摘要

A method of providing an image on an article including at least a first plastics layer (21). The method comprises transferring portions of at least one diffusible dye (22) on to the first plastics layer (21), the portions being selected so as to generate a representation of the image on the layer. The or each dye (22) is then caused to diffuse in to and partially remain in the first layer (21) and at least to mark and preferably diffuse in to a second layer (20) in contact with the first layer.
