Near-infrared cut filter and device using near-infrared cut filter

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 filter. Specifically, it relates to a near-infrared cut filter that has a sufficient viewing angle and can be used particularly preferably as a visibility correction filter for solid-state imaging (solid-state imaging) devices such as CCD and CMOS. Background technique

[0002] In recent years, televisions equipped with plasma display panels (PDPs) have been commercialized and widely used in ordinary 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, near-infrared rays are increasingly used in the remote controls of home appliances such as TVs, stereos, and air conditioners, and in the information exchange of personal computers. reason.

[0004] Therefore, the front panels of many commercially available PDPs are gradually provided wi...

Synthetic example 1

[0559] The 8-methyl-8-methoxycarbonyltetracyclo[4.4.0.1 represented by the following formula (a) 2，5 .1 7，10 ] Reaction in which 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 reaction) were replaced with nitrogen In a container, the solution was heated to 80°C. Next, 0.2 parts of a toluene solution (0.6 mol / L) of triethylaluminum and 0.9 parts of a toluene solution (concentration 0.025 mol / L) of methanol-modified tungsten hexachloride as a polymerization catalyst were added to the solution in the reaction vessel , the solution was heated and stirred at 80° C. for 3 hours, thereby performing ring-opening polymerization reaction to obtain a ring-opening polymer solution. The polymerization conversion rate of this polymerization reaction was 97%.

[0564] In a 1L stainless steel autoclave that was fully dried and replaced with nitrogen, 420.4 g of dehydrated cyclohexane, 180.2 g of p-xylene, 5-trimethoxysilyl-bicyclo[2.2.1]heptane- 48.75 millimoles (10.43 g) of 2-ene and 1425 millimoles (134.1 g) of bicyclo[2.2.1]hept-2-ene were added, and gaseous ethylene was added to bring the inner pressure of the autoclave to 0.1 MPa. Thereafter, the autoclave was heated to 75°C.
