Ink Jet Ink Composition And Method For Security Marking

View page
US Patent:
7147801, Dec 12, 2006
Filed:
Mar 12, 2004
Appl. No.:
10/800426
Inventors:
Michael Kozee - Wheaton IL,
Steven D. Looman - Wheaton IL,
John P. Folkers - Palatine IL,
Assignee:
Videojet Technologies Inc. - Wood Dale IL
International Classification:
C09D 11/00
US Classification:
25230116, 252700, 25230136, 427 8, 427157, 523160, 523161, 106 3164, 106 3115, 106 3116, 106 3132, 428 29, 428199, 382135, 382137, 382163, 382321, 283 95, 283 92
Abstract:
Disclosed is an ink composition suitable for ink jet printing comprising a luminescent compound, a solvent, and an energy active compound, and optionally a non-luminescent colorant. The energy active compound, when exposed to energy, generates one or more active species that can react with the luminescent compound to alter one or more of the characteristics of the luminescent compound. The luminescent compound can be colored or colorless. Also disclosed is a method for marking substrates comprising providing a mark comprising a luminescent compound and an energy active compound. Further disclosed is a jet ink composition suitable for printing on substrates authentication or security marks which can be rendered unreadable. The luminescence of the mark is quenched and the visible color is changed when irradiated with a light.

Thermal Ink Jet Ink Composition

US Patent:
8414695, Apr 9, 2013
Filed:
Feb 16, 2012
Appl. No.:
13/398605
Inventors:
Casey Robertson - Romeoville IL,
Anthony Selmeczy - West Chicago IL,
John P. Folkers - Palatine IL,
International Classification:
C09D 11/02
US Classification:
106 3159, 106 3158
Abstract:
A thermal ink jet ink composition includes one or more volatile organic solvents, one or more humectants, one or more binder resins, one or more dyes, and one or both of a surfactant and a plasticizer. The one or more volatile organic solvents are selected from C-Calcohols, C-Cketones, C-Cethers, C-Cesters, and mixtures thereof. The one or more humectants are present in an amount not more than 30% by weight of the ink jet ink composition. The ink jet ink composition optionally includes water up to 10% by weight of the ink jet ink composition.

Ink Containment System And Ink Level Sensing System For An Inkjet Cartridge

View page
US Patent:
2013031, Nov 28, 2013
Filed:
May 10, 2013
Appl. No.:
13/891754
Inventors:
Thomas E. Kimerling - Corvallis OR,
Mark R. Thackray - Corvallis OR,
Kenneth E. Trueba - Corvallis OR,
Scott T. Benigni - Chicago IL,
John P. Folkers - Palatine IL,
Matthew David Beasley - Dallas OR,
Terry M. Lambright - Corvallis OR,
Kevin Kuester - Freeburg IL,
Assignee:
VIDEOJET TECHNOLOGIES INC. - Wood Dale IL
International Classification:
B41J 2/175
US Classification:
347 87
Abstract:
An ink containment system for an inkjet cartridge, for storing ink for printing, comprises a rigid basin member and a rigid moveable plate. A flexible membrane is affixed to a surface of the basin member and to a surface of the plate forming an ink reservoir within the basin member, plate and flexible membrane. A spring-biased mechanism is disposed between the basin member and plate, for biasing the plate apart from the basin member, generating a negative pressure within the ink reservoir and the basin member remaining stationary relative to the movement of the plate. The basin member has a bowl-like configuration and the spring is seated within the reservoir in such a way that when the ink reservoir has collapsed due to depletion of ink, the flexible membrane and moveable plate are substantially flush with surfaces of the basin member.
