(57) [Abstract] [Problem] A cured product has a high refractive index and is excellent in heat resistance, adhesion, hardness, solvent resistance, and transparency. To develop a thermosetting resin composition having good storage stability suitable for articles for medical use. A hydroxyl group and a carboxyl group are contained in a structure using a monofunctional unsaturated group-containing aromatic compound having a biphenyl skeleton and, if necessary, a monofunctional unsaturated group-containing aromatic compound having another structure. Is synthesized, and a melamine-based or guanamine-based compound and a diluent are added thereto to prepare a resin composition. |
