The present invention relates to a photo-primed polymerizable composition for 3D printing, wherein the polymerizable composition comprises a nanogel component that comprises nanogel particles. The nanogel particles comprise a copolymer having reactive polymerizable groups capable of reacting with each other or with a reactive diluent monomer, a reactive oligomer, a resin, or a combination thereof which is present in the polymerizable composition when photo-primer; the nanogel component has a glass transition temperature of from about -50 ° C to about 20 ° C and an average molecular weight of from about 10 kg / mol to about 100 kg / mol; and the nanoparticles have a mean hydrodynamic radius which is between 1 nm and about 5 nm. |
