Patent number: 6080521Abstract: A diazotype reproduction material is a fibrous paper base having at least one overcoat, which is an acidic diazotype layer and a layer strata below the overcoat containing an anionic compound to minimize deep penetration of diazotype diazonium salts.Type: GrantFiled: June 15, 1998Date of Patent: June 27, 2000Assignee: Andrews Paper & Chemical Co., Inc.Inventors: Peter Muller, Sidney G. Garnish, Ronny L. Gonzalez

Patent number: 5102730Abstract: Written, typed, penciled, inked, xerographic and other markings on foils, opaque and transparent papers can be erased easily by mechanical means by utilizing an interlayer of alkylketene dimer with hydrophilic colloids and pigments. The provisions of such an interlayer is useful for drafting materials, xerographic and diazotype copies.Type: GrantFiled: February 20, 1990Date of Patent: April 7, 1992Assignee: Andrews Paper & Chemical Co., Inc.Inventors: Peter Muller, Henry Mustacchi, Leonard Kreicas, George Schmitz
-
Patent number: 4792515Abstract: Erasable diazotype second originals on a translucent base have become very popular because they permit correcting, deletions and additions of new information to drawings without the need to redo an entire drawing. A new barrier film composition that acts simultaneously as matrix for the diazotype coating components and controls the ease of mechanical erasure is disclosed. The second originals exhibit almost film like reprographic continuity.Type: GrantFiled: January 8, 1987Date of Patent: December 20, 1988Assignee: Andrews Paper & Chemical Co., Inc.Inventors: Peter Muller, Henry Mustacchi, George Schmitz
-
Patent number: 4743524Abstract: Diazotypes with new yellow coupler with an active methylene group are disclosed; the couplers do not migrate and excel by their relatively reduced coupling speed for greatly improved shelf life of diazotypes. In preferred embodiments the improved new diazotypes contain acetoacetoxyethyl methacrylate or acrylate as yellow coupler.Type: GrantFiled: October 17, 1986Date of Patent: May 10, 1988Assignee: Andrews Paper & Chemical Co., Inc.Inventors: Peter Muller, Henry Mustacchi, Leonard Kreicas

Patent number: 4569888Abstract: A transparentized paper with a caliper of between 0.001 and 0.015 inch and the process for its preparation is disclosed. A paper web is treated with a liquid mixture of polyesters, acid monoesters of polyols and dicarboxylic acids in non aqueous polaric solvents having admixed therein methylol derivatives of polyamino compounds, with or without a catalyst. The impregnated paper is cured by an in-situ cross-linking reaction immobilizing the impregnated material. A transparentized paper results which is resistant to water, most organic solvents and heat and is useful as tracing material as well as a translucent base for sensitizing with reprographic coatings. The transparentized paper is not resistant to alkali and can be repulped in alkaline medium for recycling. The transparentized paper also exhibits antistatic properties.Type: GrantFiled: July 13, 1984Date of Patent: February 11, 1986Assignee: Andrews Paper & Chemical Co., Inc.Inventors: Peter Muller, Henry Mustacchi, Leonard Kreicas
-
Patent number: 4478926Abstract: Zinc salts of sulfonic acids are described as stabilizers for diazotype materials.Type: GrantFiled: February 22, 1983Date of Patent: October 23, 1984Assignee: Andrews Paper & Chemical Co., Inc.Inventors: Peter Muller, Henry Mustacchi
-
Patent number: 4403028Abstract: Disclosure is made of a class of diazonium salts characterized in part by their improved thermal stability and non-flammability. The salts are useful in diazotypy.Type: GrantFiled: August 11, 1982Date of Patent: September 6, 1983Assignee: Andrews Paper & Chemical Co., Inc.Inventors: Henry Mustacchi, Arthur Gusmano, Peter Muller
-
Patent number: 4401744Abstract: Disclosure is made of a light-sensitive diazo coating composition and a light-sensitive diazotype reproduction material comprising a base with at least one coating layer comprising a light sensitive diazo compound, coupling component, a stabilizing acid and salt, and a development accelerating and stabilizing composition of 1,3-dimethylurea with urea or with thiourea, which also improves sensitizing solution compatibility and increases printing speed.Type: GrantFiled: May 6, 1981Date of Patent: August 30, 1983Assignee: Andrews Paper & Chemical Co., Inc.Inventor: Peter Muller
-
Patent number: 4343884Abstract: One component diazotype material is imagewise exposed and developed odorless and curlfree with 0.6-4.5 g/m.sup.2 per square meter of a substantially water free liquid developer in a pressure development or transfer roller apparatus.Type: GrantFiled: December 29, 1980Date of Patent: August 10, 1982Assignee: Andrews Paper & Chemical Co., Inc.Inventors: Peter Muller, Henry Mustacchi
-
Patent number: 4271227Abstract: A transparent, non-stratified, three dimensional resin reinforced fibrous sheet and the process for its preparation is disclosed. A fibrous sheet is impregnated or coated with one or more tri or higher functional monomers that can be polymerized in-situ to form three dimensional polymer resins, in close contact with the fibrous material of the sheet. A transparentized fibrous sheet results which is resistant to water and alcohols, highly and evenly translucent and useful as tracing media vellum as well as a translucent base for sensitizing with reprographic coatings.Type: GrantFiled: April 26, 1979Date of Patent: June 2, 1981Assignee: Andrews Paper & Chemical Co., Inc.Inventors: Peter Muller, Henry Mustacchi
-
Patent number: 4241690Abstract: Apparatus for coating and metering a coating on a paper web. A system is provided for mixing doctored excess coating material with fresh, make-up material and recirculating the mix by gravity flow for reapplication to the moving paper web.Type: GrantFiled: April 4, 1979Date of Patent: December 30, 1980Assignee: Andrews Paper & Chemical Co., Inc.Inventor: Peter Muller
