Definitions
- the invention relates to novel, water-dispersible or water-soluble blocked polyisocyanates stabilized against thermal yellowing, their preparation and
- aqueous one-component (1K) and two-component (2K) polyurethane systems are increasingly being used in combination with blocked isocyanates. Due to the blocking agents, there is often a thermal yellowing of the coatings produced, which is undesirable.
- Blocking agents which cause only very little thermal yellowing are known from the prior art, e.g. 3,5-dimethylpyrazole,
- 1,2,4-triazole or ⁇ -caprolactam have the disadvantage that they are either too expensive or cannot be used generally due to certain product properties.
- the blocking of polyisocyanates based on HDI with 1,2,4-triazole leads to strongly crystallizing products which are therefore unsuitable for use in paints and coatings.
- ⁇ -Caprolactam has a significantly higher deblocking temperature and is therefore not suitable for all areas of application.
- a stabilizing agent is known from US Pat. No. 5,216,078 which significantly reduces the thermal yellowing of blocked, in particular of butanone oxime, blocked isocyanates and which is a hydrazine adduct.
- EP-A 0 829 500 describes a combination of compounds as stabilizing agents for blocked polyisocyanates, one of the compounds at least one 2,2,6,6-telxame ylpiperidinyl residue, the so-called HALS (hindered amine light stabilizer) residue and the other has a hydrazide structure.

- a disadvantage of the stabilized blocked polyisocyanates mentioned above, however, is that they are only suitable for solvent-based paints and coating systems and not for aqueous systems.
- the object of the present invention was therefore to provide isocyanates which, on the one hand, are blocked and water-dispersible or water-soluble and, on the other hand, are sufficiently stabilized against possible thermal yellowing and are suitable for crosslinking aqueous 1-component and 2-component binders or paints, in particular on polyurethane and or Polyacrylate base are suitable.
