Radio frequency identification elements, including linerless or lined labels, are produced with enhanced effectiveness. The antenna is printed with conductive ink or toner, and cross-over may be provided by spot printing a non-conductive material over a portion of the antenna and then printing a conductive cross-over element on the non-conductive material. Typically the antenna is printed on one face of a web, and the radio frequency identification chip is moved into contact with the opposite face of the web so that the contacts penetrate the web and engage the antenna so that the web material acts as a dielectric. Alternatively part of the antenna on the first face may be over-printed with a non-conductive material and the chip attached to the first face passing through openings in, or penetrating, the non-conductive material to engage the antenna. A protective substrate or coating is provided on at least one of the chip and antenna, for example by heating heat expandable microspheres, or applying a substrate having hot melt adhesive. The antenna may be printed with a printing media comprising a carrier including resin and wax and containing conductive material in it, and by heating the carrier so that it becomes fluid and is applied as a thick film on the substrate, and by allowing the carrier to cool so as to provide a conductive antenna. The printing may be accomplished at a speed of about 500 feet per minute or more.

Radio frequency identification tags and labels

A release liner for business form and label constructions comprises a substrate of carbonizing bond paper having a weight of between about 35-80 grams per square meter. A radiation (e.g. U.V.) curable silicone polymer blend is coated on the first face of the substrate with a coating weight of between about 0.8-2.3 grams per square meter. The silicone polymer blend comprises a large part base silicone polymer and optionally up to 40% of tight release additive, about 1 to 5% photoinitiator, and possibly substantially inert ingredients. A paper face of the form or label having a weight of between about 65-99 grams per square meter has a hot melt permanent or removable pressure sensitive adhesive on one of its faces, either applied directly or transferred to it if coated on the silicone, the adhesive in contact with the release liner. The form or label is substantially curl free after running through a laser printer.

Pressure sensitive adhesive linerless label assemblies having a primer layer and a breakaway layer capable of being separated from each other after the label is applied to a surface, thus leaving a portion of the assembly on the surface and removing the other portion. In one embodiment, the primer layer is an ethylene/acrylic acid copolymer and the breakaway layer is polyvinyl acetate. In another embodiment, the primer layer is a polyethylene emulsion and the breakaway layer is a polyurethane emulsion. In a third embodiment, the primer layer is a composition of a UV curable bisphenol A epoxy oligomer, pentaerythritol triacrylate, and a monofunctional styrene monomer, and the breakaway layer is polyvinyl acetate.

A combined business form/identification card includes a sheet of cellulosic stock material having a barrier coating on a first portion of the sheet with an overlay of laser-printable varnish on the barrier coat. Lines of weakness are provided in the sheet in the area of the barrier coat and varnish to produce an identification card detachable from the sheet. A second portion of the sheet has indicia imaged thereon.
