Abstract: An ink is provided, which includes a resin, UV curable monomer, and photo initiator. The resin is formed by reacting a plurality of end capping agents with a dendrimer compound in an environment including esterification catalyst, inhibitor, and first solvent. The dendrimer compound is formed by reacting a multi-hydroxy compound and a plurality of hydroxy-containing epoxy compounds in an environment including alkaline catalyst and second solvent. The multi-hydroxy compound and the hydroxy-containing epoxy compounds have a molar ratio of 1:6 to 1:20, and the multi-hydroxy compound and the end capping agents have a molar ratio of 1:6 to 1:20. The end capping agents include acrylic acid, methacrylic acid, glycidyl methacrylate, or 2-amino acrylic acid. The resin and the UV curable monomer have a weight ratio of 100:30 to 100:5000, and the resin and the photo initiator have a weight ratio of 100:30 to 100:500.
