FIELD: chemistry.
SUBSTANCE: present invention relates to an adhesive composition and to a method for producing an adhesive composition. The adhesive composition contains a polyurethane composition and a latent catalyst. The latent catalyst is a product of reaction of a guanin-containing compound, carbon dioxide and water, alcohol, amine or thiol. The guanin-containing compound is
,
where R1, R2, R3 and R4 are independently selected from a group consisting of hydrogen, methyl, ethyl, propyl, isopropyl, butyl, and isobutyl, and R5 is hydrogen. This method includes adding the latent catalyst in the polyurethane composition after the formation of the polyurethane composition and activating the latent catalyst.
EFFECT: development of the polyurethane adhesive composition without solvents with latent catalysts, which is characterized by long storage life during a lamination process, but with high reaction capability after the lamination.
