However, there has been a problem that the UV absorbers described in Patent Documents 1 to 3 may inhibit the curing of the curable composition.
With respect to such problems, the present inventors have found that the ultraviolet absorber has an action of absorbing the light irradiated for curing the curable composition, and because such an action It has been found that the addition of a UV absorber into the polymerization system may result in cure inhibition.

As means for solving the above-mentioned problems, latent additives which can be activated after curing are inactivated in the above-mentioned light absorbing action in the polymerization system.

(Wherein, A is an atomic group having an ultraviolet absorbing ability, B is a photoleaving group, and k is an integer of 1 to 10).

In the compound I-1 of the present invention, the atomic group A has an ultraviolet absorbing ability. The compound I-1 of the present invention has a low ultraviolet absorbing ability before the elimination of the photoleaving group B, but exhibits an excellent ultraviolet absorbing ability based on the atomic group A after the elimination of the photoleaving group B.
Therefore, when the compound I-1 before elimination of the photoleaving group B is added, for example, into the polymerization system, the compound I-1 has a low ability to absorb ultraviolet light, so absorption of light irradiated for polymerization is caused. Performance is low and it is difficult to inhibit the curing of the polymerization system.
On the other hand, when the compound I-1 of the present invention is irradiated with light, the photoleaving group is released and exhibits excellent ultraviolet absorbing ability. Therefore, by irradiating the cured product containing compound I-1 with light, the cured product can be easily imparted with ultraviolet absorbing ability. The compound I-1 has the advantage of being less likely to cause damage to the cured product and its peripheral members such as the base material, since the compound I-1 does not need to be heat-treated to develop its ultraviolet absorbing ability.
For the above reasons, the compound I-1 has, for example, little inhibition of curing, and can easily impart ultraviolet light absorbing ability and the like to a cured product.

In addition, the compound I-1 of the present invention has a low ability to absorb light irradiated for the development of photosensitivity before desorption of the photoleaving group B. Therefore, when the compound I-1 is added to a photosensitive composition whose solubility in an alkali developer changes by light irradiation, it is possible to stably exhibit photosensitivity. In addition, the compound I-1 can easily impart ultraviolet light absorbing ability and the like to the photosensitive composition by carrying out light irradiation capable of releasing the light leaving group.
As described above, the compound I-1 has less inhibition of expression of photosensitivity with respect to the photosensitive composition, and can easily impart ultraviolet light absorbing ability and the like to the photosensitive composition.

Furthermore, the compound I-1 of the present invention can easily adjust, for example, the dispersion or dissolution stability in the composition by having a photoleaving group B.
The compound I-1 can impart excellent dispersibility in the composition by selecting the photoleaving group B such that the affinity with other components contained in the composition is improved.
Therefore, the compound I-1 can impart excellent ultraviolet light absorbing ability to the composition, and can also impart excellent dispersion stability during storage before use.

The integrated light quantity of the light irradiated for curing the composition containing the polymerizable compound etc. can be usually less than 1000 mJ / cm ² . Therefore, when the integrated light amount is in the above-mentioned range, for example, application to a photocurable composition becomes easy.

Elimination rate (%) = phenol compound (compound I-2) / phenol compound (compound I-2) + compound I-1) × 100

In addition, for Examples 1, 2 and 7 (Compounds I-1-2, I-1-3 and I-1-34), before (0 mJ / cm ² ) and after (10 000 mJ / cm) light irradiation. ^{In 2} ), the absorption spectrum of light in the wavelength range of 250 nm to 450 nm was confirmed. As a result, it was confirmed that light having a longer wavelength can be widely absorbed in a wavelength range of 250 nm or more and 450 nm or less after light irradiation, as compared to before light irradiation. The measurement results of the maximum absorption wavelength (nm) are shown in Tables 3 and 4 below.

From Tables 3 and 4, it was confirmed that compound I-1 was desorbed from the photoleaving group B by light irradiation.
Further, it was confirmed from Table 3 that the compound I-1 was able to efficiently absorb ultraviolet rays having a wide wavelength range of 250 nm or more and 450 nm or less by light irradiation. Moreover, along with that, the shift to the long wavelength side of the maximum absorption wavelength was confirmed.
From the above, compound I-1 has the phenolic hydroxyl group protected by the photoleaving group B before light irradiation and the ultraviolet ray absorbing ability is suppressed, so that the curing inhibition can be suppressed and the ultraviolet ray absorbing ability can be easily made by the light irradiation. It has been confirmed that it can be granted.

The curability and light resistance of the resulting compositions of Examples 18 to 20 and Comparative Examples 1 and 2 were evaluated by the following methods.

[Curable]
The compositions of Examples 18-20 and Comparative Examples 1 and 2 were each applied to a PET film with a bar coater to a thickness of about 3 μm. Next, after prebaking at 80 ° C. for 3 minutes, exposure was performed (20 mW / cm ² ) using an ultra-high pressure mercury lamp (UL 750) as a light source. The exposure was performed so that the exposure light amount was 500 mJ / cm ² . Under the present circumstances, the negative film made so that light transmittance might be decreased in steps in order to measure a photosensitivity (The optical density 0.05 is made into the 1st step, The optical density is 0.15 at a time for every step. An increasing step tablet was used. Then, development was carried out by washing with isopropanol (IPA) for 10 seconds in an environment of 25 ° C., followed by drying at 80 ° C. for 30 minutes. And the photosensitivity was evaluated by measuring the number of steps of the step tablet of the hardened | cured material formed on PET film. The higher the number of steps of the step tablet, the higher the photosensitivity and the better the curability. The results are shown in Table 5 below.

[Lightfastness]
The compositions of Examples 18 to 20 and Comparative Examples 1 and 2 were each applied to a glass substrate by a spin coater, prebaked at 80 ° C. for 3 minutes, and then exposed using a super high pressure mercury lamp (UL 750) as a light source. (20 mW / cm ² ). The exposure was performed so that the exposure light amount was 100 mJ / cm ² . Thereafter, the sample was further irradiated with 3000 mJ / cm ² to prepare a sample for light resistance evaluation. A 24-hour light resistance test was performed on the sample for evaluation using a Suga Test Instruments Xenon Light Resistance Tester Table Sun XT-1500L. The difference in transmittance (%) at a wavelength of 470 nm before and after the light resistance test of the sample for evaluation ((transmittance (%) before light resistance test-transmittance (%) after light resistance test) was measured. The light resistance was evaluated on the basis of the standard.

Good: The difference in transmittance (%) is less than 5% relative to the transmittance before the light resistance test.
X: The difference in transmittance (%) is 5% or more with respect to the transmittance before the light resistance test.

It shows that a cured | curing material is excellent in light resistance in light resistance evaluation being "O". The results are shown in Table 5 below.
