US Patent:

40270653, May 31, 1977

Filed:

Apr 28, 1975

Appl. No.:

5/570050

Inventors:

Bruce W. Brockett - Appleton WI
Frederick D. Weaver - Chillicothe OH

Assignee:

NCR Corporation - Dayton OH

International Classification:

B41m 500

US Classification:

428307

Abstract:

Record material is disclosed comprising paper sheet material coated with droplets of liquid wherein the liquid comprises 2,2,4-trimethyl-1,3-pentanediol diisobutyrate. Said liquid is associated on the record material with at least two color-producing reactants, at least one of which is soluble in said liquid. The liquid is associated with the reactants by either being in close proximity to both reactants or by having one of the reactants dissolved therein and being in close proximity to the other. Of the color-producing reactants, one is a chromogenic dye-precursor and one is a coreactant material capable of developing the color of the chromogenic dye-precursor when the two reactants are brought into reactive contact.

Appl. No.:

5/570051

Inventors:

Robert E. Miller - Appleton WI
Bruce W. Brockett - Appleton WI

Assignee:

NCR Corporation - Dayton OH

International Classification:

B41m 500

US Classification:

427151

Abstract:

A process of making a sensitized record sheet material is disclosed, suitable for developing color in oily, colorless, chromogenic dye-precursor inks applied thereto. Said record sheet material has a light, reactive, coating which comprises a zinc compound and a salicylic acid derivative combined in, and applied from, an aqueous system of basic pH. The coating composition is also disclosed.

Appl. No.:

6/700583

Inventors:

Robert W. Sandberg - Appleton WI
Bruce W. Brockett - Appleton WI
Kristi A. Blythe - Appleton WI

Assignee:

Appleton Papers Inc. - Appleton WI

International Classification:

B41M 522

US Classification:

346207

Abstract:

Disclosed is a pressure-sensitive recording material which comprises a support having thereon a two-layer microcapsule coating wherein the microcapsule layer adjacent to the support contains no color former. Such recording material makes possible a substantial decrease in quantity of color former required.

Filed:

Jun 5, 1979

Appl. No.:

6/045768

Inventors:

Bruce W. Brockett - Appleton WI

Assignee:

Appleton Papers Inc. - Appleton WI

International Classification:

B32B 516
B41M 516
B41M 522
C09D 1100

US Classification:

282 275

Abstract:

A pressure-sensitive record material comprising the colorless chromogenic dye Pyridyl Blue mixed with and adsorbed onto a pigment which is coated on a substrate sheet, and capsules containing an acidic resin dissolved in a suitable solvent, the capsules being coated on the same or an additional sheet. This "reverse" system (where the acidic resin rather than the dye is encapsulated) provides an improved community of properties, including improved image strength, print stability (fade resistance) and resistance to degradation. Pyridyl Blue is a mixture of the isomers 7-(1-ethyl-2-methylindol-3-yl)-7-(4-diethylamino-2-ethoxyphenyl)-5,7-dihyd rofuro[3,4-b]pyridin-5-one and 5-(1-ethyl-2-methylindol-3-yl)-5-(4-diethylamino-2-ethoxyphenyl)-5,7-dihyd rofuro[3,4-b]pyridin-7-one.
