Abstract: The present invention provides a UV curable resin composition that can be cured without going through a high-temperature heating process and has excellent adhesiveness, and a sheet using the same.
The UV curable resin composition comprises a rubber component with a diene skeleton, a photopolymerization initiator, a crosslinker and a tackifier. The composition contains a solid rubber component and a liquid rubber component at 25° C. as the rubber component with the diene. Since the UV curable composition can be cured by UV irradiation in a short time, it can be applied not only to adherends with high heat resistance but also to various parts.
