Abstract: An informational article having a separation control material disposed on a portion of the surface of the article and an information receiving layer overlying at least a portion of the separation control material and a portion of the surface. The information receiving layer is adapted to receive information thereon. A transparent tape is adhesively bonded to the information receiving layer containing the information. The transparent tape is more strongly adhered to the information receiving layer than the information receiving layer is adhered to the separation control material. In this way, removal of the transparent tape from the article removes both (i) the information receiving layer and (ii) the information overlying the separation control material from the remainder of the information receiving layer and the information. Because of this, evidence of tampering is easily, visually, detectable. An associated method is also disclosed.

Abstract: A retroreflective cube corner article which is a replica of a directly machined substrate in which a plurality of geometric structures including cube corner elements are machined in the substrate using only two sets of parallel grooves. At least two of the grooves in at least one of the groove sets are at a different groove depth.

Abstract: A thin polypropylene sheet is extruded flat, with a thickness in the range of 0.008 to 0.060 inches with a Rockwell hardness between 72 and 90 and a flexural modulus between 55,000 psi and 200,000 psi. The resultant surface may be utilized for cutting and chopping foods. A sharp knife will penetrate, but not perforate, the sheet material to not dull the knife while maintaining the integrity of the surface. When flexed around its longitudinal centerline, the sheet material develops substantial cantilever beam strength, so as to transport food articles after preparation into an appropriate container.

Abstract: The present invention provides one with a recording paper useful in ink jet recording processes. The recording paper is comprised of a substrate and a coating, with the coating comprising a pigment and a binder. The binder contains a water-soluble polymer, such as polyvinyl alcohol, and a curl behavior enhancing amount of a polyether, e.g., a polyalkylene glycol such as polyethylene glycol. Generally, the polyether has an average molecular weight of at least 400. The use of the present ink jet recording paper has been found to exhibit excellent imaging performance as well as superior curl behavior.
