Provided is a coating material resin composition which has a high refractive index and high transparency, and which does not require use of a solvent. According to the present invention, there is provide a coating material resin composition characterized by containing (1) a component (A) composed of a specific dinaphthothiophene based polyene compound having one or more polymerizable functional groups having an ethylenically unsaturated double bond, a component (B) composed of a polythiol compound, a component (C) composed of a photo-radical polymerization initiator, and a component (D) composed of a polyene compound that is not dinaphthothiophene based, and that has a lower carbon number than component (A), the component (A) being contained in a proportion within a range of 5-50 mass parts with respect to the total quantity of the composition, the component (B) being contained in a proportion within a range of 10-60 mass parts with respect to the total quantity of the composition, and the component (D) being contained in a proportion within a range of 5-85 mass parts with respect to the total quantity of the composition. |
