UV-curable resin composition for vacuum forming and replica film of real material comprising the same

A UV-curable resin composition comprising:

• a prepolymer comprising a urethane-containing oligomer;
• an acrylate monomer;
• and
• a photoinitiator,
• wherein the photoinitiator comprises a firstphotoinitiator and a second photoinitiator,
• wherein the first photoinitiator comprises 1-hydroxy cyclohexyl phenyl ketone and the second photoinitiator comprises diphenyl(2,4,6-trimethylbenzoyl)phosphine oxide (TPO),
• wherein the prepolymer is present in an amount of about 20 to 50% by weight, the acrylate monomer comprises an amount of about 15 to 30% by weight of isobornyl acrylate, an amount of about 15 to 30% by weight of 2-hydroxypropyl acrylate and an amount of about 1 to 10% by weight of hydroxyl pivalate neopentyl glycol diacrylate, and
• the photoinitiator comprises an amount of about 1% by weight to 5% by weight of the first photoinitiator and an amount of about 0.5% by weight to 1% by weight of the second photoinitiator,
• wherein the weight percentage (% by weight) is based on the total weight of the UV-curable resin composition in each case.
