Embodiment

[0545] Hereinafter, the present invention will be described with reference to examples, but the present invention is not limited by these examples at all. It should be noted that "part" means "part by weight" unless otherwise specified.

[0546] First, the measurement method of each physical property value and the evaluation method of physical property are demonstrated.

[0547] (1) Molecular weight:

[0548]Using a gel permeation chromatography (GPC) apparatus (150C type) manufactured by WATERS, equipped with an H-type column manufactured by TOSOH, the standard polystyrene conversion was measured under the conditions of o-dichlorobenzene solvent and 120°C. The weight average molecular weight (Mw) and number average molecular weight (Mn) of .

[0549] (2) Glass transition temperature (Tg):

[0550] The measurement was performed using a differential scanning calorimeter (DSC6200) manufactured by SII NanoTechnology Co., Ltd. at a temperature increase rate of 20° C. per minute...

Synthetic example 1

[0559] 8-methyl-8-methoxycarbonyltetracyclo[4.4.0.1 represented by the following formula (a) 2，5 .1 7，10 ] 100 parts of dodec-3-ene (hereinafter also referred to as "DNM"), 18 parts of 1-hexene (molecular weight regulator), and 300 parts of toluene (solvent for ring-opening polymerization) were put into the reaction after nitrogen replacement In a vessel, the solution was heated to 80°C. Next, 0.2 part of a toluene solution (0.6 mol / L) of triethylaluminum as a polymerization catalyst and 0.9 part of a toluene solution (concentration: 0.025 mol / L) of methanol-modified tungsten hexachloride were added to the solution in the reaction vessel. , and the solution was heated and stirred at 80° C. for 3 hours to perform a ring-opening polymerization reaction to obtain a ring-opening polymer solution. The polymerization conversion rate of this polymerization reaction was 97%.

[0560]

[0561] 1000 parts of the thus obtained ring-opening polymer solution was put into an autoclave...

Synthetic example 2

[0564] 420.4 g of dehydrated cyclohexane with a moisture content of 6 ppm, 180.2 g of p-xylene, and 5-trimethoxysilyl-bicyclo[2.2.1]heptane- 48.75 mmol (10.43 g) of 2-ene and 1425 mmol (134.1 g) of bicyclo[2.2.1]hept-2-ene were added, and gaseous ethylene was added to adjust the inner pressure of the autoclave to 0.1 MPa. After that, the autoclave was heated to 75°C.

[0565] 0.003 mg atom of palladium 2-ethylhexanoate (as a Pd atom) as a catalyst component and 0.0015 mmol of tricyclohexylphosphine were added to 10 ml of toluene and reacted at 25°C for 1 hour to prepare a solution. Fluorophenylboronic acid triphenylcarbon 0.00315 mmol was added to the autoclave heated to 75°C in this order to start the polymerization.

[0566] 90 minutes after the start of polymerization, 11.25 mmol (2.41 g) was added, and then 7.5 mmol (1.61 g), 3.75 mmol (0.80 g), and 3.75 mmol were added 4 times every 30 minutes. 5-Trimethoxysilyl-bicyclo[2.2.1]hept-2-ene was added.

[0567] After the ...

Abstract

PROBLEM TO BE SOLVED: To obtain a near-infrared ray cut filter which has a wide viewing angle, is superior in near-infrared ray cutting capability, has a low hygroscopicity, and is free from foreign matters and warpage.SOLUTION: The near-infrared ray cut filter includes a resin substrate (I) containing a compound (I) which has a structure derived from a compound expressed by a formula (I).

Description

technical field [0001] The present invention relates to a near-infrared cut-off filter. Specifically, it relates to a near-infrared cut filter having a sufficient angle of view and particularly preferably used as a visibility correction filter for solid-state imaging (solid-state imaging) elements such as CCD and CMOS. Background technique [0002] In recent years, televisions equipped with plasma display panels (PDPs) have been commercialized and widely spread in general households. This PDP is a display that operates by plasma discharge, and it is known that near infrared rays (wavelength: 800 to 1000 nm) are generated during plasma discharge. [0003] On the other hand, in the home, the remote control of home appliances such as TV, stereo or air conditioner, and the information exchange of personal computers increasingly use near-infrared rays. reason. [0004] Therefore, the front panels of many commercially available PDPs are gradually equipped with a filter function...
