each R2 is independently a group of the general formula (2):

—O—Y—COOR4  (2)

wherein
Y is a substituted or unsubstituted (hetero)aromatic group having 4 to 14 ring atoms, a substituted or unsubstituted saturated or partially unsaturated 4- to 14-membered (hetero)cyclic group or —(C(R5)2)o—;
R4 is a substituted or unsubstituted alkyl, alkenyl, alkynyl, cycloaliphatic, aryl, heteroaryl, heteroalicyclic group or a combination thereof;
each R5 is independently selected from the group consisting of hydrogen, a substituted or unsubstituted alkyl, alkenyl, alkynyl, cycloaliphatic and aryl group; and
o is an integer from 1 to 10;

each R3 independently is a group of the general formula (3):

—O—Y—CONR6R7  (3)

wherein
Y is as defined above;
R6 is selected from the group consisting of hydrogen, a substituted or unsubstituted alkyl, alkenyl, alkynyl cycloaliphatic, aryl, heteroaryl, heteroalicyclic group, a combination thereof and R7;
R7 is a group of the general formula (4):

—R8—SIR9p(OR10)3-p  (4)

wherein
R8 is an alkylene group, optionally interrupted by a heteroatom;
each R9 is independently selected from the group consisting of hydrogen, halogen, amino, a substituted or unsubstituted alkyl, alkenyl, alkynyl, cycloaliphatic, aryl, heteroaryl, heteroalicyclic group and a combination thereof;
each R10 is independently selected from the group consisting of a substituted or unsubstituted alkyl, alkenyl, alkynyl, and acyl group;
each p independently stands for 0, 1, or 2;

m is independently 0, 1 or 2; and
n is independently 1, 2, or 3, wherein the sum n+m is a maximum of 3;

(B) at least one capped adhesion promoter of formula (II):

B—R11—SiR12q(OR13)3-q  (II)

wherein
R11 is an alkylene group, optionally interrupted by a heteroatom;
each R12 is independently selected from the group consisting of hydrogen, halogen, amino, a substituted or unsubstituted alkyl, alkenyl, alkynyl, cycloaliphatic, aryl, heteroaryl, heteroalicyclic group and a combination thereof;
each R13 is independently selected from the group consisting of a substituted or unsubstituted alkyl, alkenyl, alkynyl, and acyl group;
q independently stands for 0, 1, or 2; and
B is a nitrogen-containing group selected from the group of formula (6), (7) or (8), wherein each R14, R14a, R14b, R14c, R15 and R16 is independently selected from the group consisting of hydrogen, a substituted or unsubstituted alkyl, alkenyl, alkynyl, cycloaliphatic, aryl, heteroaryl, heteroalicyclic group and a combination thereof;
r is 1, 2, 3 or 4; and

(C) at least one curing catalyst.
