1. A composition comprising:
(I) an ethylenically unsaturated oligomer comprising:
(a) a moiety of the structure (1):
·—Y1—Si(X)3  (1);
(b1) a moiety of the structure (2):

OG Complex Work Unit Chemistry
 or
(b2) a moiety of the structure (3):

OG Complex Work Unit Chemistry
 or
(b3) a combination of a moiety of the structure (2) and a moiety of the structure (3); and
(c) a moiety of the structure (3a):

OG Complex Work Unit Chemistry
in which (i) Y1 represents a linear or branched linking group comprising 1 or more carbon atoms, (ii) each X, which may be the same or different, represents an alkoxy group or an organic group that is inert towards isocyanate groups at temperatures of 100° C. or less, with the proviso that at least one X represents an alkoxy group, (iii) each R1, which may be the same or different, represents an organic group that is inert to isocyanate groups at temperatures of 100° C. or less; (iv) each R2, which may be the same or different, represents hydrogen or an organic group that is inert to isocyanate groups at temperatures of 100° C. or less; (v) each “—·” represents a linkage to another portion of the ethylenically unsaturated oligomer; (vi) each G1 is O or S, (vii) m has a value of 1 to 5, (viii) n has a value of 1 to 5, and (ix) ZP represents an organic group that is inert towards isocyanate groups at temperatures of 100° C. or less; and
(II) an ethylenically unsaturated oligomer different from ethylenically unsaturated oligomer (I),
wherein the sum of the amount of ethylenically unsaturated oligomer (I) and ethylenically unsaturated oligomer (II) is 1 to 99% by weight, based on the total weight of solids in the composition.
