1. A curable composition comprising component (a), component (b), component (c), and optionally component (d), wherein:
a) component (a) is one or more multistage polymers;
b) component (b) is one or more (meth)acrylic polymers (P1), which is or are the same or different in composition from any (meth)acrylic polymer present as part of the multistage polymer(s) of component (a);
c) component (c) is one or more polymerizing organic substances selected from the group consisting of tetrahydrofurfuryl methacrylate, cyclic trimethylolpropane formal acrylate, methoxy polyethylene glycol monomethacrylates containing on average from about 6 to about 15 ethylene oxide units, polyethylene glycol dimethacrylates containing from about 3 to about 7 ethylene oxide units, 1,4-butanediol dimethacrylate, trimethylolpropane trimethacrylate, ethoxylated pentaerythiritol tetraacrylates containing from about 2 to about 6 ethylene oxide units, hydroxypropyl methacrylate, ethoxylated bisphenol A dimethacrylates containing from about 1 to about 12 ethylene oxide units, tricyclodecanemethanol acrylate, dicyclodecane dimethananol diacrylate, (meth)acrylate-functionalized urethane oligomers and combinations thereof; and
d) optional component (d) is one or more photoinitiators.
