FIELD: chemistry.
SUBSTANCE: invention relates to a moisture-hardening composition for polyurethane hot-melt adhesives, use thereof as hot-melt adhesive, to a hardened composition obtained from reaction of moisture with said composition, a method of gluing bases using said composition and an adhesive article made using said method, as well as a method of reducing content of monomeric diisocyanates in polyurethane polymers. The moisture hardening composition contains (a) at least one polyurethane polymer of formula (I) which is solid at room temperature, containing aldimine groups; 
(I) and (b) at least one polyurethane polymer P containing isocyanate groups.
EFFECT: preparation of polyurethane compositions used as hot-melt adhesive, containing reactive isocyanate groups which can be obtained using a simple method from polyols and technically accessible monomeric diisocyanates, and which have low content of monomeric diisocyanates, stable during storage, can be easily processed and are distinguished by fast cross-linking.
