Abstract:
Product package, comprising a data storage device, packaging material, and an authentication system. The authentication system comprises first and second coatings coated on the storage device and the packaging material. One of the coatings comprises chromogenic microcapsules capable of reacting to produce color. The other coating comprises color developer. The coatings can be bonded to each other or a composite coating can be a self-contained color former such as on the storage device. The invention further comprises methods of affirming authenticity of a data storage device. The method comprises applying to the storage device a color-reactable coating which can react with a color-producing second composition, packaging the storage device to provide a closed and sealed packaged, opening the package, and concurrent with or after opening the package, reacting the chemical compositions to produce the color as an indication of authenticity of the data storage device.

Abstract:
The present invention is a novel thermally-responsive record material comprising a substrate having provided thereon in substantially contiguous relationship an electron donating dye precursor, an acidic developer material, a compound of the formula 1 wherein R1, R2 and R3 are independently selected from hydrogen, alkyl, alkoxy, aryl, aralkyl, aralkoxy, halogen, and alkoxyalkoxy; wherein R4 is independently selected from alkoxyalkyl, alkoxyalkoxy, and aralkoxyalkoxy, and a suitable binder therefor. In the context of the present invention the alkyl moieties in the alkyl, aralkyl, aralkoxy, alkoxyalkyl, alkoxyalkoxy and aralkoxyalkoxy preferably are eight carbons or less, and more preferably from one through four carbons. Substituents on aryl moieties in aryl, aralkyl, aralkoxy, and aralkoxyalkoxy groups can include hydrogen, alkyl, alkoxy and halogen. The alkyl group in these substituents also is eight carbons or less, and more preferably from one through four carbons. The thermally responsive record material of the invention has the unexpected and remarkable properties of enhanced image intensity or density, and/or improved thermal response.
Abstract:
Disclosed is a process for preparing a fibrous web. The fibrous web includes a microencapsulated material, such as a microencapsulated phase change material, adhered to the web. Preferably, the web is prepared in a melt-blowing or spun-bonding process. In the melt-blowing process, cooling water containing the microcapsules is used to cool melt blown fibers prior to collection on a collector. In the spun-bonding process, microcapsules are applied in liquid suspension or in dry form to a heated web, for instance, after the web has been calendared. The fibrous webs thus prepared have numerous uses, and are particularly suited to the manufacture of clothing.
Abstract:
This invention pertains to security paper and methods of making such security paper. The invention comprises a light-colored base paper having a non-protection area of a first thickness, and a protection area of a second thickness on at least one major surface of the base paper wherein the first thickness is greater than the second thickness. The base paper comprises colorant whereby the protection area exhibits a translucence when viewed using transmitted light, and exhibits the colorant as a darker color indication, relative to the non-protection area, when viewed using reflected light. Transmission of light through a combination of paper fibers and the colorant of the invention, both being disposed at the protection area, is discernibly different from transmission of light through the non-protection areas of the base paper, when viewed with a human eye.
Abstract:
Beverage and food containers made from sheet material, and methods of making such containers. Such container comprises a layer of paperboard and an expanded foam layer applied as a coating in a liquid carrier, and affixed to a paperboard substrate layer. The expanded foam has a remote surface preferably defined by intermingled peaks and valleys. The sheet material can include a protective cover layer overlying the remote surface. Such cover layer can comprise paper, plastic film, or foamed thermoplastic. The sheet material can include a heat seal layer, with the paperboard substrate layer between the heat seal layer and the expanded foam layer. Preferred composition for the foam layer is PVDC or AMM.
Abstract:
The present invention provides for a system and two methods for forming RF reflective pathways. These pathways can form a radio frequency identification tag. A first method uses a thermal transfer ribbon, coated with a conductive material that is engaged with a receiver substrate. A thermal print head will heat a composition on the thermal transfer ribbon in order to transfer it to the receiver substrate. This transfer composition forms the RF reflective pathway. In an alternative method, a receiver substrate is heated in order to react conductive material thereon. This receiver substrate is also heated by a thermal print head to form a RF reflective pathway.
Abstract:
The present invention is a novel class of compounds useful in useful in thermally-responsive record material of the type comprising a substrate having provided thereon in substantially contiguous relationship an electron donating dye precursor, and an acidic developer material. The novel compound of the invention is a compound of the formula 1 wherein P is selected from 2 wherein R1, is selected from hydrogen, alkoxy, and aralkoxy; wherein R2 is aralkoxyalkoxy when P is phenyl, and R2 is selected from aralkoxyalkoxy or alkoxyalkoxy when P is naphthyl. Said alkyl moieties are each independently from one to eight carbons, said aryl moieties each independently being unsubstituted or substituted by alkyl (C1-C8), alkoxy (C1-C8) or halogen. The compounds of the invention enable manufacture of thermally responsive record material of the invention having the unexpected and remarkable properties of enhanced image intensity or density, and/or improved thermal response. The compounds of the invention also find use in diverse applications such as emolients and softening agents for creams, lots and cosmetics.
