主权项

1. A multicomponent adhesive for producing an adhesive hydrogel, comprising
a) a first compound of the formula (I) whereinX is selected from the group consisting of SH, NH2 and alpha,beta-unsaturated carbonyl groups, andL is a linker which links the 1,2-dihydroxyphenyl unit with X, wherein the linker L is linked with the 1,2-dihydroxyphenyl unit in the 3 or 4 position; and b) at least one second compound containing at least one structural unit (II)
B-L′-Y  (II)wherein in each of the structural units (II) independently of the meaning in other structural units (II)B is a linkage point,L′ is a linker, andY is selected from the group consisting of SH, NH2 and alpha,beta-unsaturated carbonyl groups and can be reacted with the group X with formation of at least one covalent bond; and c) at least one of
(i) the second compound additionally comprising a residue Z, which independently of every other residue Z of another second compound is selected from the group consisting of SH, NH2 and alpha,beta-unsaturated carbonyl groups and can be reacted with a group Y with formation of at least one covalent bond,and(ii) at least one third compound, which independently of another third compound comprises at least two structural units (III)
B′-L″-Z′  (III)wherein in each of the structural units (III) independently of the meaning in other structural units (III)B′ is a linkage point,L″ is a linker, andZ′ is selected from the group consisting of SH, NH2 and alpha,beta-unsaturated carbonyl groups and can be reacted with a group Y with formation of at least one covalent bond.
