    摘要: A wetness indicating adhesive composition comprising an adhesive base composition incorporating a fluorescing agent in the adhesive base composition that only fluoresces when wet, and not when dry. In one embodiment, the adhesive base composition may be composed of water soluble, or at least partially water soluble, components, and in another embodiment the adhesive base composition may be composed of water sensitive components as for example one or more water insoluble polymers and a surfactant. The fluorescing agent can either be dissolved or dispersed in the adhesive base composition, and is preferably a water soluble fluorescing agent that becomes visible under ultraviolet light only when an article such as a disposable diaper becomes wet.

    摘要: An ink composition is provided which is suitable for use on plastic, bare metal, for example, tinplate or aluminum as well as on such metals having organic coatings applied to surfaces thereof. The inks are suitable for use in contact printers or in jet ink printing techniques and apparatus. The ink compositions are thermotropic, i.e. they change color in the presence of water or steam at elevated temperature and are useful as sterilization or pasteurization indicators. The inks comprise essentially a binder resin component, or mixture of such resin components, an alcohol solvent and a combination of dyes which produce a visible and permanent color change in the presence of water or steam at elevated temperatures.
