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.

Hot melt wetness indicator adhesive composition containing UV fluorescent agent

A hot melt adhesive composition is based on an isotactic polypropylene random copolymer (RCP). The composition contains about 4%-50% by weight of the RCP copolymer, about 20%-65% by weight of a compatible tackifier, about 0%-40% by weight of a plasticizer, about 0%-3% by weight of a stabilizer, about 0%-40% by weight of a wax, about 0%-60% by weight of an atactic poly-&#x3b1;-olefin (APAO), and about 0%-40% by weight of a secondary polymer. The adhesive composition may be used in a number of applications such as, for example, in disposable nonwoven hygienic articles, paper converting, flexible packaging, wood working, carton and case sealing, labeling and other assembly applications.

Hot melt adhesive composition based on a random copolymer of isotactic polypropylene

A hot melt adhesive composition based on a polymer blend of syndiotactic polypropylene (SPP) and atactic poly-&agr;-olefin (APAO). The composition contains about 15%-80% by weight of the SPP/APAO blend, about 15%-65% by weight of a compatible tackifier, about 0%-35% by weight of a plasticizer, about 0%-3% by weight of a stabilizer, and optionally, about 0%-30% by weight of a wax. The adhesive composition may be used in a number of applications such as, for example, in disposable nonwoven hygienic articles, paper converting, flexible packaging, wood working, carton and case sealing, labeling and other assembly applications.
