Ultraviolet ray-curable resin composition used in inkjet printing and optical element obtained using same

An ultraviolet curable resin composition to be used in an inkjet printing method, comprising at least:

• a component (A):
• a soluble polyfunctional vinyl aromatic copolymer, which is obtained by copolymerization of 20 to 99 mol % of a divinyl aromatic compound (a) and 1 to 80 mol % of a monovinyl aromatic compound (b), a content of a structural unit containing an unreacted vinyl group represented by the following formula (a1) derived from the divinyl aromatic compound (a) being 10 to 90 mol % with respect to a total molar number of structural units derived from all monomers:
• where R1 represents an aromatic hydrocarbon group having 6 to 30 carbon atoms;
• a component (B):
• a photocurable polyfunctional (meth)acrylate having at least two (meth)acryloyl groups in a molecule;
• a component (C):
• a photopolymerization initiator;
• and
• a component (D):
• a surfactant,
• wherein:
• a compounding amount of the component (A) is 5 to 45 mass %, a compounding amount of the component (B) is 55 to 94 mass %, a compounding amount of the component (C) is 0.97 to 20 mass %, and a compounding amount of the component (D) is 0.03 to 1 mass %;
• and
• the ultraviolet curable resin composition contains 90 mass % or more of an ultraviolet curable component.
