FIELD: chemistry.
SUBSTANCE: invention relates to an agent for inner coating metal containers for food and packaging, particularly to an agent for inner coating the uppermost surface of containers directly in contact with food or flavour substances, to a substrate with such a coating, containing a) at least one polyisocyanate, containing on average at least two NCO groups per molecule, where not less than 95% of NCO groups are blocked with a blocking agent, and b) at least one polyhydroxyl compound containing on average at least two hydroxyl groups active towards NCO groups, where the said polyhydroxl compound is polyesterpolyol, and c) auxiliary agents and additives if necessary.
EFFECT: improved properties of the coating (elasticity, adhesion).
