An aqueous adhesive composition and a method for preparing such a composition are disclosed. The composition comprises a polymer complex, the polymer complex being (A) a first component comprising (i) a first component comprising a skeletal element and (ii) a polyphenol, and (B) a second component. A second component comprising a polypeptide, oligopeptide, amino acid or polyamine. Skeletal elements include (a) polypeptides, oligopeptides, amino acids or polyamines, (b) polysaccharides, oligosaccharides or monosaccharides or glycoconjugates, or (c) lignins, lignans or lignin complexes. Polyphenols include tannin, tannic acid, flavonoids or polyresorcinol. An adhesive precursor composition comprising a first component is also disclosed. [Selection figure] None |
