James J Fuerholzer, Alejandro Zimin Sr, Peter A Caputo, James J Baluyut: Tagging of waterborne compositions with oil-soluble markers. Morton International, Wayne E Nacker, Gerald K White, May 11, 1999: US05902750 (2 worldwide citation)

A water-immiscible marker is dissolved in polyethylene glycol or other suitable carrier, and the marker so dissolved is added to a waterborne composition which is used as an additive to a waterborne or water processable composition. Subsequently, the marker is either extracted with a non-polar solve ...

Alejandro Zimin Sr, Peter A Caputo: Water-reducible dye compositions comprising solvent dyes and citrus solvents. Morton International, Wayne E Nacker, Gerald K White, February 18, 1997: US05603735 (17 worldwide citation)

Water-immiscible solvent dyes are mixed with citrus solvents and non-ionic surfactants to form a water-reducible true dye solution containing at least 35 wt % of the water-immiscible dye. The dye solution is dispersible in water and infinitely reducible.

A tag is added to an asphalt additive, typically an anti-stripping agent. The additive dye is mixed with other components of an asphalt composition and melt processed at 300.degree. F. (149.degree. C.) or above to produce an asphalt composition. Presence of the tag to identify presence of the additi ...

Alejandra Zimin, Peter A Caputo, Michael R Friswell, David L Booth, Michael P Hinton: Method of introducing dyes to ethanol. Morton International, Wayne E Nacker, Gerald K White, April 2, 1996: US05504199

A dye which is either 2-naphthalenol (phenylazo) phenyl azo alkyl derivatives and 1,4-dialkylamino anthraquinone is added to sufficient non-ionic surfactant to compatibilize it with ethanol and an solvent to produce a homogeneous solution. The homogeneous solution is added to ethanol in an amount to ...
