1. A polymer precursor composition for forming at least a portion of a polishing article, comprising:
a first precursor component comprising a cycloaliphatic epoxide;
an acrylate monomer;
a photoinitiator component which generates a photo acid when exposed to UV light; and
a viscosity thinning reactive diluent to provide the polymer precursor composition with a viscosity that enables the polymer precursor composition to be dispensed to form a portion of the polishing article by use of an additive manufacturing process.
