(a) Part A comprising:
(i) a (meth)acrylic component;
(ii) a cure accelerator represented by structure A
wherein X is H C1-20 alkyl, C2-20 alkenyl, or C7-20 alkaryl, functionalized by one or more groups selected from —OH, —NH2 or
—SH, or X and Y taken together form a carbocyclic ring having from 5-7 ring atoms; Z is O, S, or NX′, where X′ is H, C1-20 alkyl, C2-20 alkenyl, or C7-20 alkaryl, any of the latter three of which may be interrupted by one or more hetero atoms or functionalized by one or more groups selected from —OH, —NH2 or
—SH; R is optional but when present may occur up to 3 times on the aromatic ring and when present is C1-20 alkyl, C2-20 alkenyl, or C7-20 alkaryl, any of the latter three of which may be interrupted by one or more hetero atoms or functionalized by one or more groups selected from —OH, —NH2 or —SH; and n is 0 or 1; and z is 1-3;
(iii) a thermoplastic elastomer; and
