Abstract: Provided are an antenna circuit constituent body for an IC card/tag, which enhances a Q value by reducing a permittivity of a resin film of which a base material is made; and an IC card. The antenna circuit constituent body includes the base material made of resin film; and circuit pattern layers formed on each of both sides of the base material and made of aluminum foil. The circuit pattern layer includes a coiled pattern layer. Parts of the circuit pattern layers, which mutually face each other; and a part of the base material, which is interposed between the parts of the circuit pattern layers, constitute a capacitor. The circuit pattern layers are electrically connected by crimping parts. The base material includes a plurality of void-state-air layers. A relative density of the base material with respect to a density of a resin is less than or equal to 0.9.

Abstract: An emulsion type desensitizing gum comprises at least one polybasic acid monoester derivative of polysaccharide. The desensitizing gum exhibits high shelf stability and the lithographic printing plate to which the desensitizing gum has been applied hardly causes the background contamination of printed matters and is excellent in both the ink receptivity of the image areas and the desensitizing ability of the non-image areas.
