摘要： Heat-sensitive compositions which rapidly develop color upon heating and rapidly discharge their color upon cooling, comprising an intimate mixture of a 3,3-bis (p-aminophenyl) phthalide and an organic acid. The color-producing and color-discharging cycle may be reproduced many times without noticeable change in response. The novel compositions of the invention are useful as temperature indicators, thermal display media, safety papers and validation devices.

摘要： A device for giving a visual indication of the amount of residual ethylene oxide present in ethylene oxide treated solid hospital articles and other health devices. The amount of residual ethylene oxide is indicated by the difference in color exhibited by different sensitized areas of the device in the form of an opaque dark colored support member having bonded to its surface a thin film of a cholesteric liquid crystal composition in a solid film-forming binder. The film is made by laying down on the surface of the support member a solution or dispersion of liquid crystals which exhibits a change in color when in contact with ethylene oxide at a temperature from 60.degree. to 100.degree. F. in a solution of the solid binder, then evaporating the solvent. As prepared, the film is in a form adapted to be packaged with goods to be subjected to sterilization with ethylene oxide, a portion of the film being sealed within a transparent enclosure the walls of which possess a permeability to ethylene oxide no greater than that of the material of the treated goods.

摘要： A flat, water-remoistenable, adhesive-coated paper having superior resistance to curling ordinarily accompanying changes in atmospheric humidity. A powdered adhesive is mixed with a solution of triethanolamine plasticizer in toluene and methanol to form a dispersion in which outer surface portions of the adhesive particles are plasticized. When the dispersion is applied to paper and solvent evaporated, the resulting coating comprises a multiplicity of sintered adhesive particles having plasticized outer surface portions joined to one another and to the paper.

摘要： Paper, cotton cloth, wood, fiberboard, and other cellulosic products are first treated with an organic base and then treated with a halosilane. This results in the formation of an amine/silane complex within the cellulose fibers as well as on the surface of the cellulosic product. This treatment imparts oil and water repellency, adhesive properties, and dimensional stability to cellulosic products.

摘要： Improved pressure marking fibrous record material such as paper is provided wherein the rear surface is in contact with a profusion of liquid droplets of marking material such as ink. The fibers of the paper are vapor treated to render them repellent to the liquid marking material without substantially reducing the porosity of the sheet. Upon application of patterned marking pressure to the paper, the ink droplets are forced through the sheet to form a visible image of the pattern on the top surface. The repellent treatment reduces lateral flow of the ink in the sheet and improves image definition.

摘要： A two-layer adhesive coating having a dry, non-tacky surface convertible to a permanently adhesive surface by application of heat. A first co-reactant in an adhesive-containing base layer combines with a second co-reactant applied to the base layer to form a dry, non-tacky barrier layer comprising a molecular complex which dissociates upon heating to form a permanently adhesive surface.
