Curable resin composition

A method of manufacturing a three-dimensional shaped article, comprising the steps of:

• preparing a curable resin composition that comprises a first component, a second component and a curing agent;
• forming a first layer of the curable resin composition;
• photocuring the first layer of the curable resin composition based on a first slice data to shape a first part of the shaped article;
• forming a second layer of the curable resin composition;
• photocuring the second layer of the curable resin composition based on a second slice data to shape a second part of the shaped article;
• and
• removing a part of the curable resin composition from a surface of a cured product including the first part and the second part, wherein
• the second component is an oxetane compound, and
• the first component is represented by formula (1)
• where X1 and X2 are independently a divalent linking group containing an aromatic ring,
• L1, L2, L3 and L4 are independently a divalent linking group containing one or more bonds selected from the group consisting of —O—, —C—O—, —S—, —CS—, an ester bond, a urethane bond, an ether bond, a thiourethane bond and a thioether bond,
• Y1 and Y2 are independently an epoxy group, a cycloalkene oxide group or an oxetanyl group,
• n is an average value of repeating structural units and is a real number of 0.1 to 10, and
• X3 is represented by formula (1-VIII)
• where m is an integer selected so that the alkylene group has 4 to 18 carbon atoms,
• R1 and R2 are hydrogen or a methyl group, and
• * denotes a bond to L1 or L2.
