The formed coating film was exposed to light at an exposure amount of 5 J/cm 2 . For exposure, an LED exposure device (exposure wavelength: 365 nm) was used. The reaction rate of the carbon-carbon unsaturated double bond before and after exposure was calculated based on the reduction rate of the peak (1408 cm ⁇ 1 ) corresponding to C ⁇ C in FT-IR analysis. The curing rate was evaluated based on the calculated reduction rate according to the following criteria. A: Reduction rate of 90% or more B: Reduction rate of 85% or more and less than 90% C: Reduction rate of 80% or more and less than 85% D: Reduction rate of less than 80%
• Example 5 Formed using the photosensitive compositions of Example 5, Example 9, Example 13, and Example 17, which have the same composition except that the type of other photopolymerizable compound (A2) is different.
• the refractive index of the cured films was compared.
• the photosensitive compositions of Example 25, Example 29, Example 33, and Example 37 which have the same composition except that the type of other photopolymerizable compound (A2) is different, were used.
• the refractive index of the formed cured films was compared.
• the cured film was formed by the same method as the method used to measure the curing rate.
• the refractive index of the obtained cured film was measured using a prism coupler manufactured by Metricon, and the value of the refractive index of the cured film at a wavelength of 550 nm was determined.
• the measurement results of the refractive index are shown in Table 2.
