Abstract: An EMI shielding tape adherable to a surface of a structure. The tape includes a backing layer, and an adhesive layer carried on at least one side of the backing layer. The adhesive layer has an inner face bonded the backing layer, and an opposite outer face which is bondable under pressure to the structure surface to adhere the tape thereto. The adhesive layer is formulated as an admixture of a pressure sensitive adhesive (PSA) composition and one or more electrically-conductive particulate fillers. When adhered to the structure surface, the tape is substantially cleanly releasable therefrom.

Abstract: Disclosed is a recording sheet comprising a support having a layer of color developer capable of reacting with oil-soluble, basic, chromogenic dyes to produce rapidly a mark of improved color intensity and improved fade resistance. In addition to the conventionally used constituents such as binders, whitening agents, and fillers, the coating comprises (a) a phenol-formaldehyde condensate oligomer mixture, (b) an aromatic carboxylic acid, and (c) an inorganic magnesium compound, preferably magnesium oxide or magnesium hydroxide. Best results are obtained when components a, b, and c are present at ratios of 50 parts oligomer, 1.0-2.5 parts acid, and 10-40 parts magnesium compound.
