Abstract
A binary image comprising a plurality of first areas, at which a porous or particulate image-forming substance is adhered to a substrate, and a plurality of second areas, at which the substrate is free from the image-forming substance, is protected by laminating thereto a laminating sheet comprising a barrier layer, a durable layer and a support layer with the barrier layer facing the image, so that the barrier and durable layers adhere to both the first and second areas of the image. The support layer is then displaced away from the image such that the barrier and durable layers remain attached to the image. Both the barrier and durable layers are substantially transparent and the barrier layer comprises a polymeric organic material substantially impervious to the passage of hexane, isopropanol or water.
