<p>A photocurable resin composition capable of giving, e.g., a three-dimensional shape which is reduced in volumetric shrinkage and excellent in dimensional accuracy, has a high heat distortion temperature and excellent heat resistance, and is excellent in transparency and mechanical properties. The composition comprises (i) at least one imidized acrylic compound represented by formula (I) (wherein R1 represents an optionally substituted alicyclic, aromatic, or aliphatic group; R2 represents a residue of an amino alcohol; R3 represents hydrogen or methyl; and n is 1 or 2), (ii) a radical-polymerizable compound and/or cationically polymerizable compound which each is a compound other than the imidized acrylic compound, and (iii) a photopolymerization initiator. The proportion of the component (i) to the component (ii) is 80/20 to 10/90 (by weight).</p> |
