Problems solved by technology

[0006] However, when the light resistance of a window material having an infrared-absorbing resin layer containing an ionic copper compound in a transmissive resin was studied, it was found that if the window material is irradiated with ultraviolet rays for a long time, the infrared-absorbing The blackening phenomenon occurs in the resin layer, that is, the state where many tiny black spots are generated
[0007] The visible light transmittance of the window material in which such a blackening phenomenon occurs is low, so the visibility through the window material is low, and it is also a cause of accidents in the case of an automobile window.

Embodiment 1

[0124] (1) Manufacture of compounds containing copper ions

[0125] 5.00 g of a phosphorus compound (manufactured by Tokyo Chemical Industry Co., Ltd.) composed of an equimolar mixture of mono(2-ethylhexyl) phosphate and di(2-ethylhexyl) phosphate was dissolved in 15 g of toluene to form a solution. 2.37 g of copper acetate monohydrate was added to the solution, and while the solution was refluxed, acetic acid was removed, and toluene was further distilled off from the obtained reaction solution to obtain 6.04 g of copper 2-ethylhexyl phosphate as a copper phosphate compound. complexes.

[0126] (2) Production of infrared-absorbing resin composition sheet

[0127] Prepare polyvinyl butyral resin "Esreck BM-1" (manufactured by Sekisui Chemical Co., Ltd.) as a resin material, 2-ethylhexyl phosphate copper complex obtained in (1) above as an infrared absorber, Lithium acetate dihydrate as anti-black agent, and bis(2-ethylhexanoic acid) triethylene glycol as plasticizer.

[012...

Embodiment 2～8

[0132] As an anti-black agent, instead of lithium acetate 2 hydrate, sodium bicarbonate, sodium benzoate, potassium acetate, potassium carbonate, cesium acetate, magnesium acetate, and manganese acetate 4 hydrate were used respectively, except that it was performed in the same manner as in Example 1. , making a total of 7 types of laminated glass. Let these be "sample 2" - "sample 8", respectively.

Embodiment 9

[0134] (1) Manufacture of compounds containing copper ions

[0135] 63.1 g of a phosphorus compound consisting of an equimolar mixture of monooleyl phosphate and dioleyl phosphate (manufactured by Tokyo Chemical Industry Co., Ltd.) was dissolved in 180 g of toluene to form a solution, and 20.0 g of copper acetate monohydrate was added to the solution , while refluxing this solution, acetic acid was removed, and toluene was further distilled off from the obtained reaction solution to obtain 80.4 g of an oleyl phosphate copper complex as a phosphate copper compound.

[0136] (2) Manufacture of laminated glass

[0137] In Example 4 in which the anti-blackening agent is potassium acetate, except that the oleyl phosphate copper complex obtained in the above (1) was used as an infrared absorber, the same operation as in Example 4 was performed to produce an infrared absorbing Resin composition sheet, and further, using this sheet, it carried out similarly to Example 1, and laminate...

Abstract

An absorptive composition for an infrared ray which comprises an infrared ray absorbing agent comprising a di-valent ionic copper compound and a preventive agent for blackening comprising a metal salt compound; an absorptive resin composition for an infrared ray which comprises a resin component and the above infrared ray absorbing agent and preventive agent for blackening; and articles prepared by the application of the composition or the resin composition. The di-valent ionic copper compound is preferably a phosphorus-containing copper compound. The metal salt compound as the preventive agent for blackening is a compound comprising a metal selected from among an alkali metal, an alkaline earth metal and a transition metal. The absorptive composition for an infrared ray has the above infrared ray absorbing agent, is inhibited or suppressed in the blackening phenomenon due to an ultraviolet ray, and exhibits excellent transmittance of a visible light and excellent absorptivity for an infrared ray over a long period of time with stability. The above applied articles include a formed article, a sheet, a film, an intermediate film for a laminated glass, a composite having adsorptive property for an infrared ray and a window material.

Description

technical field [0001] The present invention relates to an infrared-absorbing composition and an infrared-absorbing resin composition utilizing the infrared-absorbing properties of divalent copper ions. Background technique [0002] In window materials used for lighting windows in buildings such as houses, window materials used in vehicles such as automobiles, aircraft, ships, etc., or light-transmitting materials for greenhouse construction, etc., in order to suppress infrared rays The rise of the temperature inside or in the room sometimes requires its own suppressed infrared ray transmittance. [0003] For example, if a material with low infrared transmittance is used as a window material for a car, it can also prevent the high temperature inside the car from being exposed to direct sunlight, and if a material with low infrared transmittance is used as a window material for a house, it can obtain High cold room effect. [0004] As a material to achieve such an object, a...
