AI Technical Summary
Infrared absorbing pigments have low moisture resistance, resulting in insufficient performance of films produced using compositions containing infrared absorbing pigments.
A composition containing a specific infrared absorbing pigment (such as a pyrrolopyrrole compound, a squarylium compound, a crotonium compound, etc.) and a curable compound is used to enhance the intermolecular interaction through the π-conjugated planar structure of the infrared absorbing pigment, forming a dense film to improve moisture resistance.
This forms a film with excellent moisture resistance, enhancing the visible light transmittance and infrared shielding properties of the infrared absorbing pigment, making it suitable for use in optical filters such as infrared cut filters.

[0080] <Composition>
[0081] The composition of the present invention is characterized by comprising:
[0082] An infrared absorbing pigment (A) having a group represented by formula (1) or formula (2);
[0083] curing compound; and
[0084] solvent.
[0085] According to the composition of the present invention, a film with excellent moisture resistance can be formed. The reason for obtaining this effect can be speculated as follows. It is speculated that the group represented by formula (1) or formula (2) possessed by the infrared absorbing pigment A has a structure with a broad π conjugated plane. Therefore, by having such a group in the infrared absorbing pigment, the intermolecular interaction of the infrared absorbing pigment becomes stronger, and the infrared absorbing pigment easily forms an association during film formation. Therefore, it is speculated that the composition of the present invention containing the infrared absorbing pigment A having the above-mentioned group can further improve the cohesive force of the film during film formation and form a dense film. Therefore, it is speculated that water can be inhibited from entering the film. It is speculated that, for this reason, by using the composition of the present invention, a film with excellent moisture resistance can be formed.
[0086] The composition of the present invention can be used as a composition for an optical filter. Examples of optical filters include infrared cut filters and infrared transmission filters. The infrared absorbing dye A having a group represented by formula (1) or formula (2) has excellent visible light transmittance and infrared shielding properties, and therefore the composition of the present invention is particularly preferably used as a composition for an infrared cut filter.

Furthermore, the exposure illuminance can be appropriately set, typically from 1000 W / m 2 ~100000W / m 2 (For example, 5000W / m 2 、15000W / m 2 or 35000W / m 2 The oxygen concentration and exposure illuminance can be appropriately combined, for example, the oxygen concentration can be set to 10% by volume and the illuminance can be set to 10000 W / m 2 , oxygen concentration 35% by volume and illumination 20,000 W / m 2 wait.
[0404] Next, the unexposed portion of the composition layer after exposure is removed by development to form a pattern. The unexposed portion of the composition layer can be removed by development using a developer. As a result, the unexposed portion of the composition layer in the exposure step is dissolved into the developer, and only the photocured portion remains on the support. The temperature of the developer is preferably, for example, 20 to 30°C. The development time is preferably 20 to 180 seconds.

The developed film can be post-baked in a continuous or intermittent manner using a heating mechanism such as a hot plate or a convection oven (hot air circulation dryer), a high-frequency heater, etc. in a manner that meets the above conditions. When performing the additional exposure treatment, the light used for exposure is preferably light with a wavelength of less than 400nm. In addition, the additional exposure treatment can be performed by the method described in Korean Patent Publication No. 10-2017-0122130.
[0407] (When patterning is performed by dry etching)
[0408] When forming a pattern by dry etching, the following method can be used: a composition layer formed by coating the above-mentioned composition on a support is cured to form a cured layer, a patterned photoresist layer is formed on the cured layer, and then the cured layer is dry-etched using an etching gas using the patterned photoresist layer as a mask. When forming the photoresist layer, a pre-baking treatment is preferably performed.

[0617] (Manufacturing Example 1) Method for manufacturing films using the compositions of Examples 1 to 73 and Comparative Examples 1 to 2
[0618] Each composition was applied to a glass substrate by spin coating and heated at 100°C for 2 minutes on a hot plate to obtain a composition layer. The obtained composition layer was exposed to light using an i-ray stepper FPA-3000i5+ (manufactured by Canon Inc.) at a irradiation rate of 1000 mJ / cm 2The entire surface was exposed with an exposure dose of 1.0 μm. Subsequently, heating was performed at 180° C. for 5 minutes using a hot plate to produce a film having a thickness of 1.0 μm.
[0619] (Manufacturing Example 2) Method for manufacturing a film using the compositions of Examples 101 to 108 and Comparative Examples 101 to 102
[0620] Each composition was applied on a glass substrate by spin coating, and then cured by heating at 100° C. for 2 minutes and then at 200° C. for 8 minutes using a hot plate to obtain a film having a thickness of 1.0 μm.
[0621] (Manufacturing Example 3) Method for manufacturing a film using the compositions of Examples 201 to 207 and Comparative Examples 201 to 202
[0622] Each composition was cast on a glass substrate, dried at 20° C. for 8 hours, and then peeled from the glass substrate. The peeled coating film was further dried at 100° C. under reduced pressure for 8 hours to obtain a film having a thickness of 0.1 mm, a length of 60 mm, and a width of 60 mm.
[0623] <Evaluation>
[0624] (Spectral characteristics)
[0625] The obtained film was measured for spectrophotometry using a spectrophotometer (U-4100, manufactured by Hitachi High-Tech Corporation), and the absorption spectrum in the wavelength range of 400 to 1500 nm was measured. The maximum absorbance (Absλmax) at a wavelength of 700 to 1500 nm was measured, and the "average absorbance at 400 to 550 nm" when this maximum absorbance was set to 1 was evaluated according to the following evaluation criteria. The evaluation results are shown in the table below. It can be said that the smaller the average absorbance at 400 to 550 nm, the steeper the spectral shape, and the better the spectral characteristics, which achieve both high transparency in the visible light region and high colorability in the near-infrared region.
[0626] -Evaluation Criteria-
[0627] A: less than 0.05
[0628] B: 0.05 or more and less than 0.1
[0629] C: 0.1 or more and less than 0.2
[0630] D: 0.2 or more
[0631] (moisture resistance)
[0632] The resulting film was placed at 110°C and 85% relative humidity for 100 hours and subjected to a humidity test. For each film before and after the humidity test, a spectrophotometer (U-4100, manufactured by Hitachi High-Technologies Corporation) was used to measure the maximum absorbance (Absλmax) at a wavelength of 700 to 1500 nm and the minimum absorbance (Absλmin) at a wavelength of 400 to 550 nm. The absorbance ratio, expressed as "Absλmax / Absλmin," was calculated. The absorbance ratio change rate, expressed as the following formula, was then calculated from the absorbance ratio before and after the humidity test, and humidity resistance was evaluated according to the following evaluation criteria. The evaluation results are shown in the table below.
[0633] Absorbance ratio change rate = {(absorbance ratio of the film before the humidity test - absorbance ratio of the film after the humidity test) / absorbance ratio of the film before the humidity test} × 100 (%)
[0634] -Evaluation Criteria-
[0635] A: Absorbance ratio change rate ≤ 2%
[0636] B: 2%<absorbance ratio change rate≤4%
[0637] C: 4% < absorbance ratio change ≤ 7%
[0638] D: 7% < absorbance ratio change ≤ 10%
