Visible images can be generated from the printed ink upon exposure to UV or infrared light. The water repelling agent renders the image waterproof and differentiates the printed image from the substrate, which allows the image to be detected upon exposure to water or other aqueous mixture. Suitable inks can be used in conventional printing methods, such as jet printing, lithography, offset printing and impact printing. Also provided are substrates imaged with these security printing inks.Type: GrantFiled: April 5, 1999Date of Patent: August 3, 2004Assignee: NCR CorporationInventors: Yaoping Tan, Maurice W. Lewis

Patent number: 6743835Abstract: The invention relates to a process for preparing nondusting free-flowing pigment concentrates with removal of the water from pigment suspensions comprising polymers and dispersants in a fluidized bed drier. The resulting bead-form pigment concentrates are nondusting and readily free-flowing. The invention further embraces the use of pigment concentrates prepared in this way for coloring plastics and polymers.Type: GrantFiled: December 5, 2001Date of Patent: June 1, 2004Assignee: Goldschmidt AGInventors: Werner Schäfer, Manfred Scheiba, Stefan Stadtmüller, Markus Weimann, Karlheinz Rümpler, Ulrich Walter

Patent number: 6686417Abstract: Polyacrylamide is made by inverse emulsion polymerisation using an oil phase including at least one ester based oil, particularly a vegetable oil, using a primary emulsification system including a polymeric carboxylic surfactant; a low HLB emulsifier; and an oil phase structurant, particularly an ester wax such as beeswax. The use of the combination emulsifier enables the use of vegetable oils especially rape seed (including canola) oil as the continuous in the polymerisation step.Type: GrantFiled: March 3, 1999Date of Patent: February 3, 2004Assignee: Imperial Chemical Industries PLCInventors: Steven Irene Jozef Reekmans, Phillip Cornet
