Patent number: 4066585Abstract: Intaglio and flexographic printing processes employing solvent-free inks, solid at room temperature but molten at printing temperatures, are disclosed, as are inks suitable therefor, said inks comprising a pigment and a thermoplastic binder having a softening point between 90.degree. C. and 160.degree. C., said binder comprising a synthetic polyamide resin or synthetic polyesteramide resin, each resin being the condensation product of (1) an acid component comprising a dimerized fatty acid and a monocarboxylic acid and (2) an amine component comprising a diamine and, in the case of the polyesteramide resin, additionally comprising a diol and/or alkanolamine.Type: GrantFiled: August 3, 1976Date of Patent: January 3, 1978Assignee: Schering AktiengesellschaftInventors: Horst Schepp, Manfred Drawert

Patent number: 4063754Abstract: A process is provided for producing a pressure-sensitive carbonless record sheet comprising the steps of preparing a hot melt coating composition, the hot melt coating composition being water insoluble and having a melting point of from about 60.degree. C to about 140.degree. C. The hot melt coating composition includes a chromogenic material. The chromogenic material is a meltable color developer of the acidic electron accepting type. The hot melt coating composition is heated to a temperature above its melting point and the heated coating composition is applied to a substrate, the coating composition being applied at a coat weight of from about 0.2 pounds to about 8.0 pounds per 3300 square feet of substrate. The coating composition is set by cooling the coated substrate. A novel liquid chromogenic coating composition is produced, the coating composition having a melting point of from about 60.degree. C to about 140.degree.Type: GrantFiled: May 7, 1976Date of Patent: December 20, 1977Assignee: The Mead CorporationInventors: Dale Richard Shackle, Ainslie Thomas Young, Jr.

Patent number: 4060262Abstract: A sensitized record sheet for developing useful color in oily, colorless, chromogenic dye-precursor inks applied thereto. Said record sheet is acid-reacting and bears a liquid ink comprising a non-evaporable liquid organic solvent having dissolved therein an acidic phenolic resin and a lower alkyl gallate.Type: GrantFiled: March 24, 1976Date of Patent: November 29, 1977Assignee: The Standard Register CompanyInventor: Theodore Maierson

Patent number: 4060651Abstract: Stiffeners in the form of spaced, narrow bands or lines of flowable, quick-setting material are applied to one side of a moving paper web to be used as computer paper. The stiffeners are applied either immediately before or during the time the paper web is partially wrapped around a cylindrical drum so that the material will set to a solidified condition while it is on the drum to set up a molecular pattern in each stiffener line, causing the paper web to be inherently biased in one direction. Guide means is provided for directing the paper web onto and off the drum. The material may be applied by applicator guns or wheels as the paper web moves through a rotary printing press and as it moves toward a line hole punch apparatus, perforating means and a fan-folding mechanism.Type: GrantFiled: February 23, 1976Date of Patent: November 29, 1977Inventor: Frederick A. DaMert
