FIELD: chemistry.

SUBSTANCE: invention relates to aqueous compositions for gluing substrates, a method of obtaining such compositions, as well as a method of making latent-reactive coatings, films and powders from said compositions. The aqueous compositions for gluing substrates contain: polymers dispersed in water, having groups capable of reacting with isocyanate, such as urethane groups and urea groups; at least one dispersed solid aliphatic polyisocyanate which is not surface-active, with softening temperature higher than or equal to 40°C; one or more compounds of group (subgroup) 5 and 6 elements, in which the oxidation state of said element is at least +4; and optionally other additives and auxiliary materials.

EFFECT: obtaining novel compositions for gluing substrates and latent-reactive coatings, films and powders based thereon, which are stable during storage and stable with respect to colour.
