Photocurable resin composition for forming support regions

A photocurable resin composition for use in forming support regions when producing a photochemically fabricated 3D object by means of the inkjet method using a photocurable resin composition, wherein the photocurable resin composition for forming said support regions comprises, in proportions based on a total mass of the photocurable resin composition for forming said support regions,

• (A) from 2 to 20 mass % of an N-hydroxyalkyl (meth)acrylamide (I) represented by the following general formula (I):
• (where R1 represents a hydrogen atom or a methyl group and R2 represents a C2-4 straight-chain or branched alkylene group);
• (B) from 2 to 20 mass % of (meth)acryloyl morpholine (II) represented by the following formula (II):
• (where R3 represents a hydrogen atom or a methyl group);
• (C) from 3 to 30 mass % of a (meth)acrylate compound containing at least one (meth)acryloyloxy group;
• (D) from 40 to 90 mass % of a polyhydroxy compound having two or more hydroxyl groups;
• and
• (E) from 0.1 to 5 mass % of a photo-radical polymerization initiator.
