• S-2 Equal amount (mass) mixed solvent of tripropylene glycol monomethyl ether and dipropylene glycol monomethyl ether
• ⁇ Curing rate evaluation> After coating the photosensitive composition on the silicon substrate, the film made of the photosensitive composition was heated at 100° C. for 2 minutes to form a coating film having a thickness of 0.2 ⁇ m. The formed coating film was exposed at an exposure amount of 5 J/cm 2 . The reaction rate of carbon-carbon unsaturated double bonds 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. From the calculated reduction rate, the curing rate was evaluated according to the following criteria. ⁇ : Reduction rate of 92% or more ⁇ : Reduction rate of 90% or more and less than 92% ⁇ : Reduction rate of 80% or more and less than 90% ⁇ : Reduction rate of less than 80%
• ⁇ Film thickness evaluation> After coating the photosensitive composition on the silicon substrate, the film made of the photosensitive composition was heated at 100° C. for 2 minutes to form a coating film having a thickness of 0.2 ⁇ m. The formed coating film was exposed at an exposure amount of 5 J/cm 2 . The cured film obtained by exposure was heated at 100° C. for 10 minutes. The mass reduction rate of the cured film was obtained from the mass of the cured film before and after heating. Based on the calculated mass reduction rate, film loss was evaluated according to the following criteria. ⁇ : mass reduction rate of 1% by mass or less ⁇ : mass reduction rate of more than 1% by mass and 5% by mass or less ⁇ : mass reduction rate of more than 5% by mass
• the photosensitive composition was allowed to stand in a constant temperature device at 25°C. After 1 week, 1 month, 3 months, and 6 months from the start of standing, the dispersion state of the inorganic fine particles (B) in the photosensitive composition was visually observed, and the inorganic fine particles (B ) was evaluated for dispersibility.
• A No separation or sedimentation after 6 months.
• Good No separation or sedimentation after 3 months, but separation or sedimentation was observed after 6 months.
• ⁇ No separation or sedimentation after 1 week, but separation or sedimentation was observed after 3 months.
• x Separation or sedimentation was observed after 1 week.
• the compound (A1) which is the radically polymerizable compound (A) having the structure contained in the above formula (A1), and the compound (A1 ) in combination with other radically polymerizable compound (A2) other than ) gives a cured film that is easily cured well and is resistant to weight loss by heating, and the inorganic fine particles (B) are long-lasting. It can be seen that the period is stable and dispersed.
• the photosensitive composition of the comparative example which does not contain the compound (A1) having the structure included in the above formula (A1) as the radically polymerizable compound (A), is difficult to cure satisfactorily and its weight is reduced by heating. It can be seen that an easily cured film is obtained and the inorganic fine particles (B) cannot be stably dispersed for a long period of time.
