摘要:
A confidential information bearing article comprising a cover sheet adhered to a base sheet is provided which is capable of providing hidden confidential information to a recipient. Through the use of camouflage, obscuring, and opacifying and reflectivity increasing coatings, the paper used for the mailer becomes effectively opaque, and information printed on the inside of the article is substantially unreadable from the outside. The article includes an adhesive for securing the base sheet and cover sheet and perforations along the edges to assist the recipient in opening the article.

A document is provided having a solvent sensitive and/or pressure sensitive ink printed thereon which reacts to the application of a solvent and/or pressure to form a visible stain or image. The ink includes a first composition of solvent soluble, water insoluble dye particles, a binder, and optionally, an opacifier. Alternatively, the first composition may be combined with a second composition which includes an encapsulated solvent and optionally a stilting material. The first and second compositions may be printed on the document in separate steps or printed together as a self-contained composition. The ink may be printed on the entire surface of the document or only on selected areas thereof.

A linerless continuous series of pressure sensitive adhesive labels is provided which have on one or more selected portions thereof a series of imagable coatings which may be activated to form colored images or areas. The series of labels include a web having first and second surfaces, with a series of imagable coatings of color formers and color developers on the first surface of the web. A coating of a release material overlies the imagable coatings on the first surface of the substrate, and a coating of a pressure sensitive adhesive is positioned on the second surface of the web. The series of labels are wound or stacked so that the coating of pressure sensitive adhesive contacts the release material to permit individual labels to be dispensed.

A thermally imagable business record such as a form, tag, label or the like is provided in which selected areas of the record may be activated to form an image upon exposure to heat. In one embodiment, at least one selected area of a substrate surface contains a thermally imagable coating of initially colorless color formers and color developers while the remaining areas of the substrate are left uncoated. The substrate may be pre-coated to provide a smooth, non-porous base coat for the thermally imagable coating, and may also include a protective coating layer to protect the subsequently printed thermal image.
摘要:
A thermally imagable business record, such as a form, label, tag, or the like is provided which may be activated to form human and/or machine readable images as well as different colored images. The record comprises a substrate having a thermally imagable coating on substantially its entire surface which forms a first color when activated, and having a desensitized area on at least one area of its surface which may be overcoated with a thermally imagable coating capable of forming a different color upon activation than the first thermally imagable coating. The first thermally imagable coating provides images which are of machine readable quality, while the additional thermally imagable coatings provide images of a different color to designate selected areas on the form or label to a user.
摘要:
A security document is provided containing a color-forming composition having an insulating material therein which allows the document to be passed through heated printing devices such as laser printers without the problem of premature color development. The color-forming composition includes a mixture of a color former, a color developer, and an insulating material. In a preferred embodiment, a toner adhesion-enhancing composition containing an insulating material is applied over the color-forming composition. The security document may be used to provide an authentication feature and/or an indication of attempted alterations from the use of solvents, heat or abrasion.

摘要:
A laminated product is provided including a carrier sheet, a polymeric film ply, a polymeric card ply, and a radiation-curable laminating adhesive. The polymeric film ply is secured to the carrier sheet and extends over a cut-out portion formed in the carrier sheet. The polymeric card ply is positioned within the cut-out portion. Either the film ply, the card ply, or both, are transparent to electromagnetic radiation. The radiation-curable laminating adhesive is positioned to secure the polymeric card ply to the exposed ply portion and comprises a bonding agent, a monomer, an oligomer, a tackifier, and a photocatalyst. The bonding agent is present in a quantity sufficient to improve the bonding characteristics of the adhesive composition. The monomer is present in a quantity sufficient to (i) increase the flexibility of the adhesive composition, and (ii) increase the tendency of the adhesive composition to release substantially cleanly from a surface to which it is bonded. The oligomer is present in a quantity sufficient to increase the dimensional stability of the adhesive composition. The tackifier is present in a quantity sufficient to increase the uncured tack of the adhesive composition. The photocatalyst is present in a quantity sufficient to increase the tendency of the adhesive composition to cure upon exposure to electromagnetic radiation.
摘要:
A web or sheet product is provided which is coated on at least a portion of its surface with a bond-enabling material for adhering toner particles on the surface of the sheet. The sheet product can be used as a mailer or confidential form which is sealed using toner particles as the adhesive. The bond-enabling material may be a polymer which is coated on the sheet as a liquid and then cured to form a film on the surface of the sheet. The bond-enabling material is resistant to melting or degrading when exposed to temperatures used for fusing toner particles, and additionally may act as a tie coat to enhance the adhesion of toner particles to the surface of the sheet. The bond-enabling material may be coated on the peripheral edges of the sheet, and toner particles are printed over the bond-enabling material on the peripheral edges of the sheet. The sheet is folded and sealed by the application of heat and pressure to the edges of the sheet.
