Abstract:
A marker assembly in substantially rectangular form of edge dimensions ranging from about 140 millimeters by 210 millimeters to about 290 millimeters by 420 millimeters, comprising:(i) a support sheet having a surface provided with a porous coating of latent curable material for receiving printed indicia, which coating is subsequently cured to render the indicia substantially indelible, (ii) a layer of adhesive on the surface of the support sheet not carrying the porous coating, (iii) a non-stress relieved plastic release sheet of at least 90 micrometers thickness removably adhered to and covering at least part of the adhesive layer, and (iv) a spacing device projecting from the surface of the release sheet facing away from the remainder of the assembly, said spacing device being a means of providing air gaps at least in an edge region of the assembly for facilitating separation of individual assemblies from a stack of such assemblies, which region will be the leading edge region when the assembly is fed from said stack to sheet handling equipment and wherein the spacing device is adhered to the release sheet by an adhesive that permits movement of the spacing device at temperatures experienced by the device during curing of the porous coating.
