Abstract: Disclosed is a forgery-preventing film having a structure in which a thermoplastic resin film is attached to both faces of a light-shielding layer processed for forgery prevention. It is impossible to recognize the letter information to be protected in the forgery-preventing film without peeling the information-concealing layer therefrom.

Abstract: A pressure-sensitive adhesion-processed sheet which can be easily stuck without forming blisters by air-entrapment, is less expensive, can be easily re-stuck, and has favorable working characteristics. The pressure-sensitive adhesion-processed sheet includes a sheet base material and a pressure-sensitive adhesive layer having plural small valleys and plural small peaks.

Abstract: The object of the invention is to provide an electrophotography recording paper having excellent density, color tone, gradation, fixing properties and recording qualities, while having excellent water resistance and durability. The object may be obtained by constructing an electrophotography recording paper 1 by laminating a recording layer 3 comprising a synthetic resin film having a coating layer 4 on at least one side of a base material layer 2 comprising a paper material having a water resistance. The electrostatic capacity of the electrophotography recording paper is controlled at 10 pF/cm2 or more. It is desirable that the synthetic resin film as the recording layer 3 be a polyester film, particularly a polyethylene terephthalate film.

Abstract: Recording sheets are disclosed which comprise a support (I) having formed on a surface thereof an image-recording/receiving layer (II) selected from an ink-receiving layer (IIa) for receiving a water-based ink ejected by an ink-jet recording technique, a thermosensitive recording layer (IIb), a coating layer (IIc) for laser printing and a thermal transfer image-receiving layer (IId). The support (I) has a laminated structure comprising a plain weave fabric (A) and, bonded thereto with an adhesive, a water-proof stretched resin film (B) having a machine-direction Clark stiffness (S value) of from 8 to 300, a transverse-direction Clark stiffness of from 8 to 300 and a thickness of from 20 to 300 .mu.m. The image-recording/receiving layer (II) is provided on the support on the side where the stretched resin film layer (B) is present. The inventive recording sheets have a tough surface and have both excellent ink absorption and clarity of developed color.

Abstract: A sheet for an illuminated signboard is described which has as a base a composite sheet which is a plain weave fabric (I) having laminated on one or both sides thereof a microporous film (II) which is a stretched thermoplastic resin film containing fine white inorganic particles, where the sheet for an illuminated signboard satisfies the following requirements (1) to (4):(1) it has an opacity of from 80 to 100%;(2) it has a whiteness of from 85 to 100%;(3) it has a total light beam average reflectance of from 12 to 40%; and(4) it has a total light beam average transmittance of from 70 to 95%.

Abstract: The invention provides composite synthetic paper comprising (A) plain weave fabric and (B) synthetic paper comprising a stretched resin film having an opacity of not less than 85%, a void volume of from 10 to 60%, and a thickness of from 30 to 500 .mu.m, with or without (C) opacifying layer interposed between (A) and (B), in which synthetic paper (B) may be composed of a biaxially stretched thermoplastic resin film as a base layer and a uniaxially stretched thermoplastic film containing 8 to 65% by weight of an inorganic fine powder as a paper-like layer. The composite synthetic paper is excellent in printability, tear resistance, waterproofness, sewability, and opacifying properties and useful as material for aprons, shop curtains, disposable clothing, maps, outdoor posters, signboards, hangers, flags, etc.

Abstract: A coated resin film having excellent offset printability is described, which comprises a polyolefin resin film base material layer having formed on both the surfaces thereof a solvent permeation preventing layer for preventing the permeation of a solvent in offset printing ink compositions and further having formed on one or both the surfaces of the solvent permeation preventing layers a coating agent layer.

Abstract: A delivery slip system which comprises a delivery slip which is adhered on an article to be delivered, the delivery slip being provided with a necessary printing on the front and a pressure-sensitive layer in a predetermined area on the back thereof; a see-through waterproof covering film strip which is possible to write on having a width larger than said delivery slip; one or more copy slips having the same width as the delivery slip and disposed below said delivery slip; and a release paper strip applied to the back of the last and lowest copy slip; said delivery slip proper being bonded to the back of said covering film strip; said waterproof covering film strip being provided with an adhesive layer in the upper and lower edge portions on the back thereof; and said release paper strip adhereing to said waterproof covering film strip in the upper and lower edge portions thereof, and a method for producing the same.
