Abstract: An irreversible thermochromic ink composition can include thermochromic pigment capsules dispersed in a carrier. The irreversible thermochromic pigment capsules can include an inner core having a color changing dye, a color activator for activating the color changing dye, and a wax, an outer core surrounding the inner core and comprising a color destroying agent, and a shell surrounding the outer core. Alternatively, the irreversible thermochromic pigment capsules can include an inner core having a color destroying agent and a wax, an outer core surrounding the inner core and comprising a color changing dye and a color activator for activating the color changing dye, and a shell surrounding the outer core. Written marks made with the irreversible thermochromic inks can be rendered a different color or substantially colorless by application of a sufficient amount of heat to melt or substantially liquefy the wax in the irreversible thermochromic pigment capsules.

Abstract: A surface treatment solution for a recording paper on which ink-jet recording is performed with a water-based ink, the surface treatment solution includes calcium alginate which is contained by 0.008 wt % to 0.074 wt % in the surface treatment solution, sodium alginate which is contained by 0.013 wt % to 0.084 wt % in the surface treatment solution, a water-soluble organic solvent, and water.

Abstract: The invention provides a composition comprising an aqueous solution of 0.1-20 wt. % of a poly(amine) and 0.1 to 50 wt. % of a carboxylated carbohydrate having an average molecular weight of at least 100,000 D and a degree of carboxyl substitution of at least 5%, which carboxylated carbohydrate has been obtained by subjecting a corresponding original carbohydrate to an oxidation treatment whereby carboxyl and aldehyde groups are obtained by oxidation of hydroxyl groups of the original carbohydrate, after which the oxidised carbohydrate so obtained is contacted with a reducing agent whereby at least part of the aldehyde groups that were obtained in the oxidation treatment are reduced to hydroxymethyl groups, whereby the carboxylated carbohydrate comprises at least part of the reducing agent and/or its reaction product(s), and wherein the carboxylated carbohydrate forms a complex with the poly(amine).

Abstract: Radiation curable ink compositions for ink jet contain radiation curable monomers containing vinylether and acrylate functions.

Abstract: Derivatized Arabinogalactan can be utilized in a variety of compositions to impart functionality without imparting negative rheological affects when the amount of the derivatized Arabinogalactan is increased in the composition. This is particularly important in the personal care industry, where it is desirable to have the flexibility to adjust the amount of derivatized Arabinogalactan depending upon the results it is desired to deliver to the user without negatively impacting the overall viscosity of the personal care composition.

Abstract: The present invention provides a transparent coating comprising a resin and a heat responsive material that increases in opacity when exposed to heat. Preferably, the transparent coating is free or substantially free of a pigment or dye. An example of a heat responsive material is a carbohydrate. The present invention further provides a coating composition comprising a solvent, a resin, and a heat responsive material that increases in opacity when exposed to heat. The present invention further provides a method for creating a mark on a substrate comprising providing to the substrate the transparent coating to obtain a coated substrate and exposing a selected area of the coated substrate to heat to create the mark. The substrates can be marked with a laser.
