- the photopolymerizable compositions manufactured in Examples 49 to 63 of the present invention can manufacture cured films exhibiting low haze values, sensitivity, refractive index, and transmittance, and implement excellent inkjet characteristics.
- the cured films of the photopolymerizable compositions manufactured in Examples 49 to 63 have excellent modulus and flexibility, and excellent discoloration stability under high temperature and high humidity conditions.
- Comparative Examples 1 to 10 had very poor haze characteristics and flexibility characteristics. That is, it can be seen that Comparative Examples 1 to 10, which did not use the first highly flexible monomer according to one embodiment of the present invention, could not manufacture a cured film having excellent haze characteristics and flexibility characteristics.
- Comparative Examples 11 to 24 had very poor haze characteristics and flexibility characteristics. That is, it can be seen that Comparative Examples 11 to 24, which did not use the first highly flexible monomer according to one embodiment of the present invention, could not manufacture a cured film having excellent haze characteristics and flexibility characteristics.
- Comparative Examples 25 to 32 had very poor haze characteristics. That is, it can be seen that Comparative Examples 25 to 32, which did not use the second highly flexible monomer according to one embodiment of the present invention, could not manufacture a cured film having excellent haze characteristics.
- Comparative Examples 33 to 40 could not simultaneously implement a low haze value and a low refractive index value.
- Comparative Examples 33 to 40 which did not use the second highly flexible monomer according to one embodiment of the present invention, could not produce a cured film exhibiting a low haze value and a low refractive index value together.
- the photopolymerizable composition according to one embodiment of the present invention has excellent inkjet characteristics and can implement a cured film exhibiting low refractive index characteristics, high transmittance characteristics, and low haze characteristics after curing.
- the cured film including the cured product of the photopolymerizable composition has improved modulus and elongation, so that the mechanical properties can be improved, and discoloration is effectively suppressed even under high temperature and high humidity conditions.
