A moisture-curable polyurethane hot melt adhesive composition having good oleic acid resistance, especially when exposed to 100% pure oleic acid under aging condition of 65° C. and 90% relative humidity, wherein the adhesive composition comprises, consists essentially of or consists of a moisture-curable polyurethane prepolymer, the prepolymer being a reaction product of at least one amorphous polyester polyol containing an aromatic group and at least one polyisocyanate, preferably at least one polyisocyanate containing an aromatic group, wherein the aromatic group is comprised in the polyurethane prepolymer in a content of no less than 23 wt. %, preferably no less than 25 wt. %, more preferably no less than 30 wt. %.

Two-component solventless polyurethane adhesive compositions comprising an isocyanate component and an isocyanate-reactive are disclosed, the compositions comprising an isocyanate component comprising an isocyanate-terminated prepolymer and an isocyanate-reactive component comprising a hydroxy-terminated polyurethane resin, a polyether polyol, a phosphate ester adhesion promoter, and, optionally, a bio-based polyol. Methods for forming laminate structures are also disclosed, the methods comprising forming an adhesive composition by mixing an isocyanate adhesive component comprising an isocyanate-terminated prepolymer and an isocyanate-reactive adhesive component comprising a hydroxy-terminated polyurethane resin, a polyether polyol, a phosphate ester adhesion promoter, and optionally, a bio-based polyol, applying the adhesive composition to a surface of a first substrate, and bringing a surface of a second substrate into contact with the adhesive composition on the surface of the first substrate, thereby forming the laminate structure. Laminate structures are also disclosed.

A waterproof sound-transmitting sheet, which interposes an adhesive layer composed of a material having micropores formed therein, thus smoothing the flow of the air between a waterproof sound-transmitting layer and a support layer. The waterproof sound-transmitting sheet includes a waterproof sound-transmitting layer formed of a film having elasticity, an adhesive layer having one surface adhered to one surface of the waterproof sound-transmitting layer, and a support layer having one surface adhered to the other surface of the adhesive layer; and the adhesive layer includes a substrate having a pore formed therein and an adhesive agent formed on both surfaces of the substrate.

The present invention relates to a method of manufacturing a cellulosic film (cellulose film), particularly a cellulosic food packing film, especially a detectable cellulosic film, which cellulosic film comprises detectable particles incorporated therein, as well as to the cellulosic film thus produced and to its applications and usages (i.e. its use).

A wettable barrier fabric is provided that exhibits barrier function to dry particles and splashed liquids while also exhibiting wettability and wicking properties. A garment formed from a wettable barrier fabric that has good absorption properties and that retains good barrier properties is also provided.

This disclosure describes a composition that includes a bulk diffuser that includes a film having a major surface; the film includes a polymer, and a scattering element. The scattering element includes a silicone bead having a mean particle diameter in a range of 2 micrometers (μm) to 9 μm. The linear density of the film is at least 5.1 W.sub.i*μm, wherein the linear density equals the product of the mass fraction of the silicone bead (W.sub.i) and film thickness in micrometers (μm). This disclosure further describes methods of making the film and the bulk diffuser and methods of using the film including, for example, as a bulk diffuser in a sign box.
