The present invention relates to an aqueous dispersion at least containing (A) at least one polyurethane, (B) at least one fresh sol and (C) optionally further additives, wherein the at least one polyurethane is anionically hydrophilized, to a process for producing the dispersion, to the use of the dispersion for producing an adhesive composition, to a corresponding adhesive composition, to an adhesive laminate containing at least one substrate bonded with this adhesive composition, to a process for producing an adhesive laminate and to the use of a fresh sol for achieving a thickening effect in an aqueous polyurethane dispersion.

The present disclosure is directed to a two-component bonding agent composition and a process for applying a layer of the bonding agent composition to substrate layers to make laminates.

An antistatic composition contains an ambient-temperature molten lithium salt dihydrate, and one of a polymerizable compound, a plastic resin, an elastomer and an adhesive resin in which the lithium salt dihydrate is dispersed. The lithium salt dihydrate contains two types of lithium salts with different molecular weights from each other. The two types of the lithium salts are selected from a group of lithium salts each containing an anion having a fluoro group and a sulfonyl group.

Embodiments described herein provide a coating composition including an aqueous acrylic/polyurethane dispersion. The aqueous acrylic/polyurethane dispersion is produced from at least one isocyanate component, a polyol mixture, and at least one acrylate solvent. The polyol mixture includes a polyester polyol and at least two different oleo-based polyols. The coating composition exhibits improved chemical resistance without sacrificing other properties, such as hardness and abrasion resistance.

The invention relates to a thermally activatable reactive adhesive film comprising a carrier film made of thermoplastic polyurethane, which is coated on at least one side with a latently reactive, thermally activatable adhesive compound.

A problem to be solved by the invention is to provide a method for producing leather-like sheets with excellent chemical resistance and discoloration resistance utilizing an aqueous urethane resin composition. The invention provides a method for producing a leather-like sheet in the form of a laminate including a film, the method including forming the film by applying an aqueous urethane resin composition onto a substrate and drying the composition, the aqueous urethane resin composition including a urethane resin, a nonionic emulsifier and an aqueous medium, the urethane resin being one obtained by reacting a polyol including a carboxyl group-containing polyol, an aromatic polyisocyanate and a chain extender, the urethane resin having a urea bond content of not more than 0.3 mol/kg. The film is preferably used as a skin layer and/or a topcoat layer of the leather-like sheet.
