Abstract: Adhesive hot-melt formulations with a main polymeric component, of at least one isotactic metallocene butene-1 polymer composition, that has a low viscosity, and that has a bimodal composition, directly obtained during polymerization, in two consecutive and separate reaction steps. Moreover, said hot-melts include less than 5% by weight of at least one viscosity modifier that is not solid at room temperature. Such unusually low level of said additives, surprisingly allows to attain substantially improved levels both of high adhesiveness and cohesion. The adhesive hot-melt formulations include less than 5% by weight of a polyethylene wax or of a blend of polyethylene waxes, that characterized by a highly linear/non-branched structure and by an exceptionally low Polydispersity Index. The presence of such peculiar polyethylene waxes, that are partially incompatible with the butene-1 polymer composition, allows to use the disclosed hot-melt formulations even in the presence of fibrous or perforated substrates.

Abstract: The present application discloses novel hot-melt adhesive formulations, with excellent processability, even in processes at high line-speed and at a relatively low temperature, the formulations suitable for strongly bonding substrates that have openings, holes, voids or pores, both macroscopic and microscopic ones, like perforated plastic films, both with bidimensional or tridimensional structure; fibrous substrates, both woven and non-woven; porous plastic films, and the like, all mentioned substrates being widely used for the manufacturing of absorbent hygienic articles.

Abstract: The present invention relates to wetness indicator compositions that comprise at least one leuco dye and one color developer in a hot-melt adhesive matrix. Upon contact with water or with water-containing fluids, said wetness indicator compositions are apt to change their color from a colorless state to a colorful state or from a first colored state to a second colored state having a color different from the first one; in particular, from a first colorless, white, or translucent state to a second state having a visible color, or vice versa. The disclosed wetness indicator compositions can be used as wetness/fluid indicators in various applications, e.g. in packaging articles and in absorbent articles; in an absorbent mat or sheet or operatory cloth for medical use; in a wound dressing product; in an absorbent mat or sheet for food products.

Abstract: A wetness indicator composition comprising at least one pH-indicator colorant, from about 0.001% to about 75% by weight of at least one color-stabilizer, and from 0.1% to 70% by weight of at least one hardening agent, and wherein the wetness indicator has a defined and properly selected hot to cold solidification rate, hardness and melt point.

It has now been found that such stabilizers can greatly increase the stability of alkyd resins against melt viscosity variations after thermal aging. The alkyd resins can be used as the predominant component of a hot melt adhesive which can be employed for instance as a construction adhesive in the manufacture of disposable absorbent articles.
