FIELD: chemistry.
SUBSTANCE: invention relates to blocked polyisocyanates, applied for obtaining binding agents for lacquers, paints and elastomers in form of systems of hot drying for application of coatings on substratum from wood, metals, mineral substances, products from concrete, textile, glass or plastics, as well as hardener for polyol components. Blocked polyisocyanates have general formula (I): 
Polyisocyanates are obtained by interaction of polyisocyanates of general formula (II) 
with secondary amines of general formula (III) 
and hydrophilising means D-H, where D represents residue of cationic, anionic and/or non-ionic hydrophilising means.
EFFECT: obtaining of polyisocyanates, which have lower temperature of hardening or temperature of hot drying, due to which compositions of materials, which contain such polyisocyanate, are more stable in storing at room temperature and more stable at high temperatures of hot drying.
