    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.
