Patent number: 4150174Abstract: 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.Type: GrantFiled: May 30, 1975Date of Patent: April 17, 1979Assignee: Dennison Manufacturing CompanyInventor: William R. Lawton

Patent number: 4150187Abstract: Pressure-sensitive reusable transfer elements of the squeeze-out type having a microporous resinous ink-releasing layer firmly bonded to a flexible foundation. The invention is characterized by the use of a bonding layer which is applied to the foundation as an aqueous composition comprising a water-dispersible, water-insoluble resinous binder material which dries to form a tacky, adhesive layer.Type: GrantFiled: September 2, 1975Date of Patent: April 17, 1979Assignee: Columbia Ribbon and Carbon Manufacturing Co., Inc.Inventor: Albert E. Brown

Patent number: 4147509Abstract: A pressure-sensitive recording material which comprises a substrate bearing a dye-forming component and a binder. The dye-forming component is a spirodipyran of the formula ##STR1## where A is the radical of a fused benzene or naphthalene ring (which rings may or may not be substituted), R.sup.1 is alkyl of 1 to 16 carbon atoms, substituted or unsubstituted phenyl or phenalkyl of 7 to 10 carbon atoms, R.sup.2 is H or together with R.sup.1 is a trimethylene or tetramethylene bridge which is unsubstituted or substituted by from 1 to 3 alkyl, R.sup.3 is benzyl or .beta.-phenylethyl and R.sup.4 is benzyl, .beta.-phenylethyl or substituted or unsubstituted phenyl, or R.sup.3 is alkyl of 1 to 4 carbon atoms and R.sup.4 is substituted or unsubstituted phenyl or R.sup.3 is benzyl and R.sup.4 is .beta.-cyanoethyl. The recording materials give violet to bluish green colorations (copies) only on paper coated with an electron acceptor.Type: GrantFiled: January 9, 1978Date of Patent: April 3, 1979Assignee: BASF AktiengesellschaftInventors: Hans Baumann, Andreas Oberlinner

Patent number: 4143891Abstract: The negotiable document which may be used, e.g. by airlines includes a cover sheet provided with a hot spot carbon or other image transfer medium and at least one underlying sheet fully or partly coated with microcapsules of a dye intensifier and attractor. When information is imprinted on the cover sheet, the microcapsules of the dye intensifier in the underlying sheet are burst to wet the sheet and, thus, allow impregnation of the image transferred by the hot spot carbon into the fibers of the sheet. At the same time, the dye within the hot spot carbon is attracted into the sheet. The impregnation of the sheet is sufficient to prevent removal of the image from the underlying sheet without first destroying the sheet or mutilating it in such a manner that the defalcation effort is obvious.Type: GrantFiled: December 29, 1976Date of Patent: March 13, 1979Assignee: Transkirt CorporationInventor: Frank Neubauer

Patent number: RE34721Abstract: A manifold form assembly has a front page and a back page, with each page having image-receiving areas disposed thereon. The front page image-receiving areas are non-overlapping with the back page image-receiving areas. A pressure-sensitive image-transferring system is provided integral with the assembly to transfer pressure-created images formed on the front and back page image-receiving areas. Duplicate front and back pages receive images transferred by the image-transferring system. A stub connects the original pages, the image-transferring system, and the duplicate pages into an integral form assembly.Type: GrantFiled: March 1, 1991Date of Patent: September 6, 1994Inventor: Gary J. Thompson

Patent number: RE35273Abstract: A manifold form assembly has a front page and a back page, with each page having at least one image-receiving area disposed thereon. The original front page is disposed on one side of a first sheet and the original back page is disposed on the other side of the first sheet. The first sheet is movable between a first position in which the original front page is exposed for completion and a second position in which the original back page is exposed for completion. A pressure sensitive image-transferring system is provided integral with the assembly to transfer pressure-created images formed on the front and back page image-receiving areas. Duplicate front and back pages receive images transferred by the image-transferring system. A stub connects the original pages, the image-transferring system, and the duplicate pages into an integral form assembly. In one embodiment, a set of carbons transfer the pressure-created images from the original front sheet to the duplicate front sheets.Type: GrantFiled: April 4, 1995Date of Patent: June 11, 1996Inventor: Gary J. Thompson
