However, even when the above-described UV absorber is added, it may not be possible to obtain a cured product with sufficient durability. For example, when an ultraviolet absorber is added to a photocurable composition, the ultraviolet absorber absorbs the light irradiated for photocuring, and the decomposition of the photopolymerization initiator may be inhibited, resulting in poor curing. be.

In order to solve such problems, the action as an ultraviolet absorber is inactivated in the composition before curing, and a latent additive such as a latent ultraviolet absorber that can be activated after curing is added. known to use.

However, even when a latent UV absorber is used, there are cases in which a cured product with sufficient durability cannot be obtained or production of a cured product is difficult.

Compound A used in the present invention is a compound represented by the general formula (A1), (A2) or (A3).
As will be described later, the compound A can show ultraviolet absorption ability by removing R ⁹ protecting the phenolic hydroxyl group by heating. Therefore, the composition of the present invention containing the compound A can produce a cured product excellent in durability, ie, light resistance.
In order to further increase the durability of the cured product using compound A, the amount added must be increased, but the increased amount may reduce the development speed of the photocurable composition. In the present invention, by using compound A and compound B together, durability can be imparted without increasing the amount of compound A, and the development speed of the photocurable composition can be maintained.
Conventional ultraviolet absorbers, when added to the polymerization system, absorb the light irradiated for photocuring, thereby inhibiting the decomposition of the photopolymerization initiator, thereby inhibiting the curing of the photocurable composition, Decrease sensitivity. On the other hand, compound A has a low absorbability of light irradiated for photocuring during polymerization, so inhibition of decomposition of the photopolymerization initiator is suppressed, and curing of the photocurable composition is inhibited. Because it does not, the decrease in sensitivity can be suppressed. Furthermore, compound A can maintain good sensitivity even when used in combination with compound B as a photostabilizer.

A UV absorber having a phenolic hydroxyl group tends to aggregate in the composition due to the influence of the phenolic hydroxyl group, and it is difficult to increase the amount added to the composition. On the other hand, Compound A has a structure in which the phenolic hydroxyl group is protected by ^R9 , and is therefore excellent in dispersion stability in the composition. As a result, the compound A can be easily added to the composition and easily dispersed in the cured product, compared with conventional UV absorbers having a phenolic hydroxyl group, and its function can be fully realized. can be demonstrated in

Furthermore, as described above, since the phenolic hydroxyl group of compound A is protected by R ⁹ , it is possible to suppress the occurrence of curing inhibition of the photocurable composition. becomes easier.

When a phenolic UV absorber is combined with compound B, the amount of light transmitted along the thickness direction of the composition is greatly reduced, for example, the adhesion between the cured product and the substrate is reduced, and curing It causes a problem that the object is easily peeled off from the base material. However, in the present invention, the absorption of light irradiated during curing can be suppressed by using compound A as described above, and as a result, a cured product in which peeling from the substrate is suppressed can be obtained.

Furthermore, when the composition of the present invention contains, as a resin component, a component such as a photosensitive resin whose solubility in an alkaline developer changes upon irradiation with light, the ability to absorb irradiated light is low for developing photosensitivity. , it becomes possible to stably express the photosensitivity. Accordingly, the composition of the present invention can be a photosensitive composition that provides a cured product with excellent photosensitivity and excellent durability.

The compound A has a structure in which a phenolic hydroxyl group is protected by a protecting group ^R9 , and can be rendered to have ultraviolet absorbing ability by elimination of the protecting group ^R9 . Having ultraviolet absorption ability means being able to absorb light in the wavelength range of 250 nm or more and 450 nm or less. In the present invention, the maximum absorption wavelength after elimination of the protecting group R ⁹ is in the wavelength range of 250 nm or more and 600 nm or less, preferably 250 nm or more and 400 nm or less, more preferably 260 nm or more and 390 nm or less, particularly It is preferably 280 nm or more and 380 nm or less. This is because the composition of the present invention facilitates production of a durable cured product.

As a method for measuring the maximum absorption wavelength, for example, a compound dissolved in a solvent such as chloroform at a concentration of 0.01 g/L is used as an evaluation sample, and this is placed in a quartz cell (optical path length 10 mm, thickness 1 .25 mm) and measure the absorbance using an absorptiometer (for example, U-3900 (manufactured by Hitachi High-Tech Science)).

The compound A can have a maximum absorption wavelength in the wavelength range of 250 nm or more and 600 nm or less on the shorter wavelength side than the compound after elimination of the protecting group ^R9 .
The difference between the maximum absorption wavelength of the compound A and the maximum absorption wavelength of the compound after elimination of the protective group ^R9 can be 1 nm or more, preferably 1 nm or more and 100 nm or less, and particularly 1 nm or more and 50 nm. The following are preferred. This is because when the difference in the maximum absorption wavelength is within the above range, the compound A is excellent in the effect of suppressing curing inhibition.

The protecting group ^R9 of the compound A can be released by heating.
The temperature at which the protecting group R ⁹ contained in the compound A is eliminated may be 100° C. or higher and 300° C. or lower, preferably 120° C. or higher and 250° C. or lower, particularly 150° C. or higher and 230° C. or lower. Preferably. This is because the above temperature facilitates the production of a durable cured product of the composition.

The detachment temperature of the protective group can be measured, for example, as the temperature at which the first weight loss begins in the weight change measured using a STA (simultaneous differential thermogravimetric analyzer). As for the measurement conditions, 10 mg of compound A is filled in a measurement container, the measurement temperature range is 30° C. to 350° C., and the temperature increase rate is 10° C./min. STA7000 (manufactured by Hitachi High-Tech Science Co., Ltd.) and the like can be used as the simultaneous differential thermal thermogravimetric measurement device.

Also, from the viewpoint of increasing the change in the ultraviolet absorbability, both R ¹ and R ² are preferably —OR ⁹ .

It is preferably an arylalkyl group having 7 to 20 carbon atoms or a heterocyclic ring-containing group having 2 to 20 carbon atoms, more preferably a hydrogen atom or an alkyl group having 1 to 40 carbon atoms, particularly a hydrogen atom or carbon An alkyl group having 1 to 5 atoms is preferable, and a hydrogen atom and an unsubstituted alkyl group having 1 to 5 carbon atoms are particularly preferable. This is because the compound A has a large change in ultraviolet absorption ability and can suppress the occurrence of curing inhibition.

The matters regarding R ¹ and R ² described above also apply to R ¹ ′ and R ² ′ in the general formula (A2) and R ¹ ″ and R ² ″ in the general formula (A3).

R ⁹ is preferably an alkyl group having 1 to 20 carbon atoms or an alkenyl group having 2 to 20 carbon atoms, more preferably an alkyl group having 1 to 20 carbon atoms, particularly carbon An alkyl group having 1 to 8 atoms is preferred. This is because the compound A has a large change in ultraviolet absorption ability. Moreover, the composition of the present invention facilitates the production of a durable cured product.

R ⁹ is an alkyl group having 1 to 20 carbon atoms, an alkenyl group having 2 to 20 carbon atoms, an aryl group having 6 to 20 carbon atoms, an arylalkyl group having 7 to 20 carbon atoms, or 2 carbon atoms. -20 heterocyclic ring-containing groups in which the methylene group at the end on the oxygen atom side is substituted with -CO-O-, i.e., -CO-O- is bonded to the end on the oxygen atom side It is preferable that there is

More specifically, it is preferably an alkyl group having 1 to 20 carbon atoms or an alkenyl group having 2 to 20 carbon atoms, in which the methylene group at the terminal on the oxygen atom side is substituted with —CO—O—. .
The alkyl group having 1 to 20 carbon atoms or the alkenyl group having 2 to 20 carbon atoms in which the methylene group at the end on the oxygen atom side is substituted with —CO—O— means “*—CO—O—R ³⁰⁰ " is a group. In the above formula, * represents a bond with an oxygen atom, and R ³⁰⁰ represents an alkyl group having 1 to 19 carbon atoms or an alkenyl group having 2 to 19 carbon atoms.

R ⁹ is preferably an alkyl group having 1 to 20 carbon atoms in which the terminal methylene group on the oxygen atom side is substituted with —CO—O—, particularly the terminal methylene group on the oxygen atom side is — It is preferably an alkyl group having 1 to 8 carbon atoms substituted with CO-O-, and among these, particularly the terminal methylene group on the oxygen atom side is substituted with -CO-O-. It _is preferably an alkyl group having 1 to ₈ carbon atoms that is not Preferably. This is because ^R9 can be easily eliminated from the compound A by heating, for example, to form a phenolic hydroxyl group.

As the content of the compound A, the composition is excellent in sensitivity, as long as it is possible to produce a cured product having the desired durability, 0.01 per 100 parts by mass of the solid content of the composition It can be from 0.05 parts by mass to 20 parts by mass, more preferably from 0.1 parts by mass to 15 parts by mass, and particularly 0.5 parts by mass. It is preferably at least 10 parts by mass. This is because the composition containing the compound A in such an amount can produce a cured product having excellent durability, and has good sensitivity to facilitate production of the cured product. Moreover, it is because the said compound A can be stably disperse|distributed in a composition with the above-mentioned content.
In addition, solid content means the sum total of all the components other than a solvent. Moreover, in the present invention, the content is based on mass unless otherwise specified.

Generally, the thinner the film thickness of the member used, the higher the content of the ultraviolet absorber is required. Therefore, even when the cured product of the composition is used for a thin film member, the lower limit of the content of the compound A is 100 mass of the solid content of the composition, from the viewpoint of exhibiting sufficient ultraviolet absorption ability. It is preferably 0.6 parts by mass or more, more preferably 0.8 parts by mass or more, and particularly preferably 2 parts by mass or more. This is because by setting the lower limit of the content in this way, it is possible to provide a sufficient ultraviolet absorbing ability even in the case of a thin film member.

The content of the compound A varies depending on the content of the solvent and the like, but it can be 0.001 parts by mass or more and 20 parts by mass or less in 100 parts by mass of the composition.

In the present invention, it is preferred that a polymerizable compound is included. This is because the composition can more effectively exhibit the effect of facilitating the production of a cured product. Specifically, by containing the compound A which absorbs little irradiated light, the composition can more effectively exhibit the effect of facilitating the production of a cured product. Moreover, it is because the said composition can be used as a photocurable composition, a thermosetting composition, etc. by including a polymerizable compound as said resin component.
