    摘要： The invention describes a color-developing composition that contains at least four major components: (1) a leuco dye or a combination of leuco dyes, (2) an electron-withdrawing color-developer agent or a combination of color-developers that can form colored complexes with the leuco dyes, (3) a separator or combination of separators that when present in sufficient amounts, can prevent the formation of the colored complexes between the color-developer and leuco dyes, all contained within (4) an encapsulation matrix that includes at least one film-forming and one aqueous-insoluble polymer. All of the foregoing components are dissolved together in a volatile organic solvent medium to form a homogeneous solution that can be applied as an ink on substrates, which can be incorporated as part of absorbent articles or personal care products.

    摘要： 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.
