A method of manufacturing a transfer device comprising an optically variable transferable layer (3) on a carrier (1). A continuous adhesive layer (6) is coated on the transferable layer (3) and is selectively treated, for example by printing, to provide areas which are not bondable to a substrate under normal transfer conditions. When the treated adhesive layer (6) is contacted with a substrate (8) under normal transfer conditions, only non-treated areas of the adhesive adhere to the substrate so that only areas of the transferable layer (3) corresponding to the non-treated adhesive areas are transferred to the substrate (8) on separation of the carrier (1) and substrate. <IMAGE> |
