Abstract
Provided are a photocurable resin composition that can be suitably used for an optical three-dimensional shaping method, and a cured product obtained by photocuring the composition and a three-dimensional shaped object including the cured product. The photocurable resin composition contains a compound represented by the formula (1) and a compound containing two or more epoxy groups.
Claims8
A photocurable resin composition comprising:
- a compound represented by the following formula (1):
- where:
- “m” represents an integer of from 2 to 50;
- R1s each represent H or CH3, and R1s may be identical to or different from each other;
- and
- a plurality of R2s represent saturated hydrocarbon groups each having 2 to 8 carbon atoms in a main chain thereof, which may be identical to or different from each other, and the saturated hydrocarbon groups may each have a side chain;
- a compound containing two or more epoxy groups;
- a photoradical polymerization initiator;
- and
- a photocationic polymerization initiator.
