Description

[Technical field]

[0001] The present invention relates to a thermoplastic resin composition, an optical member, and a camera module. [Background technology]

[0002] Devices such as smartphones, tablets, and digital cameras are often equipped with optical sensing components. Such optical sensing components obtain light with wavelengths in the near-infrared region, and use this to obtain information about the shape of the subject, sensing the shape of the subject. In this case, light with wavelengths outside the near-infrared region becomes noise, so it is cut off by filters or the like.

[0003] An example of a technique for cutting light with wavelengths outside the near-infrared region using a filter or the like is described in Patent Document 1. Patent Document 1 discloses an optical filter having a substrate and a dielectric multilayer film on at least one surface of the substrate, the substrate having a transparent resin layer containing a compound (A) having an absorption maximum in the wavelength range of 600 nm or more and less than 750 nm and a compound (S) having an absorption maximum in the wavelength range of 750 nm or more and 1050 nm or less, or having a transparent resin layer containing the compound (A) and a transparent resin layer containing the compound (S), and characterized in that the filter satisfies the following requirement (a): (a) In the wavelength region of 800 to 1000 nm, the average transmittance measured from the perpendicular direction of the optical filter is 5% or less. Patent Document 1 describes that the optical filter has excellent near-infrared blocking properties, little incidence angle dependency, and excellent transmittance properties in the visible wavelength range and an effect of reducing multiple reflected light in the near-infrared wavelength range.

[0004] [Patent Document 1] International Publication No. 2016 / 158461 Summary of the Invention [Problem to be solved by the invention]

[0005] As electronic devices become smaller, there is an increasing demand for optical components that combine sensing and imaging functions. This is because a single optical component that combines sensing and imaging functions eliminates the need to install a separate sensing lens and imaging lens, making it possible to save space.

[0006] When a single optical component has both a sensing function and an imaging function, it is necessary to cut off both light in the wavelength range of 300 to 400 nm and 700 to 800 nm that is unnecessary for both sensing and imaging.In addition, it is necessary to transmit both light in the wavelength range of 900 to 1000 nm used for sensing and light in the wavelength range of 500 to 600 nm used for imaging.

[0007] As a result of their investigations, the inventors have discovered that by blending a specific metal compound into a resin composition, it is possible to cut out light with wavelengths of 300 to 400 nm and 700 to 800 nm, which is unnecessary for both sensing and imaging, by having the resin composition absorb it, and to transmit light with wavelengths of 900 to 1000 nm, which is used for sensing, and light with wavelengths of 500 to 600 nm, which is used for imaging, and thus completed the present invention.

[0008] The present invention has been made in consideration of the above circumstances, and provides a thermoplastic resin composition that can cut out light in the wavelength range of 300 to 400 nm and 700 to 800 nm, which is unnecessary for both sensing and imaging, by having the resin composition absorb it, and that can transmit light in the wavelength range of 900 to 1000 nm used for sensing and light in the wavelength range of 500 to 600 nm used for imaging.

[0090] [Measurement of glass transition temperature] The glass transition temperature (Tg) of the thermoplastic resin (A) was measured using a differential scanning calorimeter under the following conditions. In an N2 (nitrogen) atmosphere, the resin (A) was heated from room temperature to 200°C at a heating rate of 10°C / min, and then held for 5 minutes, and then cooled to -20°C at a heating rate of 10°C / min, and held for 5 minutes.

[0091] [Measurement of maximum absorption wavelength] 0.05 parts by mass of metal compound (B) or other metal compound was dissolved in 100 parts by mass of chloroform to obtain a chloroform solution. The obtained chloroform solution was placed in a quartz cell for a spectrophotometer with an optical path length of 1.0 mm, and a wavelength range of 200 nm to 1000 nm was measured at 25°C using an ultraviolet-visible near-infrared spectrophotometer (manufactured by Hitachi High-Tech Science Corporation, product name: UH-4150), and the maximum absorption wavelength in the measured wavelength range was measured. The maximum absorption wavelength refers to the wavelength at which the transmittance shows a minimum value and the minimum value is the smallest, that is, the maximum absorption wavelength.

[0092] [Preparation of samples for transmittance measurement] A resin composition was obtained by adding the metal compound (B) in the amount shown in Table 1 to pellets made of thermoplastic resin (A) and melt-kneading them at 260°C using a Labo Plastomill.

The content of the metal compound (B) or other metal compounds was adjusted so that the plate obtained by the above method had a light transmittance of 70% at a wavelength of 500 nm.

[0093] [Transmittance evaluation] The transmittance of the obtained plate was measured at 1 nm intervals from 200 nm to 1000 nm using an ultraviolet-visible near-infrared spectrophotometer (Hitachi High-Tech Science Corporation, product name: UH-4150). From the obtained data, the average transmittance from 300 nm to 400 nm, from 500 nm to 600 nm, from 700 nm to 800 nm, and from 900 nm to 1000 nm were calculated. The results are shown in Table 1. The average transmittance was evaluated according to the following criteria. For light with wavelengths of 300 to 400 nm and 700 to 800 nm, these are wavelengths that become noise, and so lower transmittance is desirable, so it was set that the lower the transmittance, the better the result. On the other hand, for light with wavelengths of 500 to 600 nm and 900 to 1000 nm, it was set that the higher the transmittance, the better the result. The evaluation results are also shown in Table 1. <300nm or more and 400nm or less> A: 5% or less B: More than 5% and less than 15% C: More than 15% <500nm or more and 600nm or less> A: 75% or more B: 60% or more but less than 75% C: Less than 60% <700nm or more and 800nm ​​or less> A: 5% or less B: More than 5% and less than 20% C: More than 20% <900nm or more and 1000nm or less> A: 75% or more B: 60% or more but less than 75% C: Less than 60%
