26 Claims

1. A photocurable composition comprising:

a) a (meth)acrylate-functionalized polyether urethane component, wherein the (meth)acrylate-functionalized polyether urethane component is present in an amount of about 20% to about 60% by weight based on the total weight of the curable composition;

b) a (meth)acrylate monomer;

c) an organic filler; and

d) a photoinitiator,

wherein when exposed to UV or visible light the curable composition forms a cured reaction product, the cured reaction product demonstrates a loss of mass of: 1) less than 2% when exposed to acidic, aqueous conditions of a pH=1.5 for about 4 weeks at a temperature of about 50° C. and/or 2) less than 3% when exposed to basic, aqueous conditions of a pH=12.5 for about 4 weeks at a temperature of about 50° C.
