The invention relates to hybrid dispersions comprising nitrocellulose-polyurethanepolyurea particles (NC-PU dispersions) with accelerated drying behavior as compared with the known systems, and also to their use in coating materials.

NC-PU dispersions with accelerated drying

Disclosed herein are two-component polyurethane reactive compositions containing polyisocyanates and components carrying active hydrogen which are stabilized against separation with a compound in solution containing a NH group or NH.sub.2 group and a C--N multiple bond or N--N multiple bond.

Two-component polyurethane reactive compositions

Disclosed herein is a two-component polyurethane adhesive containing an isocyanate component a), an active hydrogen containing component which is stable against demixing b), optionally a catalyst for the reaction of a) with b) and optionally an auxiliary agent and an additive, characterized in that an active hydrogen containing component which is stable against demixing b) contains at least one hydroxyl group-containing low molecular weight chain lengthening agent having at least one C-C double bond or C-C triple bond and having a molecular weight of at least 86 and a functionality of at least 2 and containing no carboxyl groups.

Two-component polyurethane adhesives

Disclosed herein is an adhesive and a process for bonding with the adhesive containing an isocyanate prepolymer a), an isocyanate reactive component b) and a catalyst for the reaction of a) and b), characterized in that the catalyst comprises a compound corresponding to the following formula ##STR1## wherein R.sup.1 and R.sup.2 may be identical of different and denote an alkyl group having 1 to 4 carbon atoms,
