Embodiment 1

[0109] (1) Preparation of dispersion liquid

[0110] 40 parts by weight of triethylene glycol di-2-ethylhexanoate (3GO), 0.28 parts by weight of ITO particles (manufactured by Mitsubishi Materials Co., Ltd.), 0.004 parts by weight of naphthalocyanine compound ("FF-IRSORB203" made by Fujifilm Co., Ltd.) Parts by weight, and 0.234 parts by weight of yellow dye (anthraquinone dye, maximum absorption wavelength 450nm, "ORACET Yellow GHS" manufactured by Ciba Japan Co., Ltd.) are mixed, and after adding a phosphoric acid ester compound as a dispersant, pass through a horizontal bead mill Mix to obtain a mixed solution. Then, 0.1 part by weight of acetylacetone was added to the mixed liquid with stirring to prepare a dispersion liquid. The volume average particle diameter of the ITO particles in the dispersion liquid was 35 nm. The naphthalocyanine compound ("FF-IRSORB 203" manufactured by Fujifilm Corporation) contained copper.

Embodiment 2～9 and comparative example 1～5

[0117] Dispersions, interlayer films for laminated glass, and laminated glasses 1 and 2 were prepared as in Example 1 except that the composition of the interlayer film for laminated glass was changed as shown in Table 1 below.

[0118] (Evaluation)

[0119] (1) Determination of Tts and Tds (Solar Direct Transmittance)

[0120] The above-mentioned Tts and the above-mentioned Tds of the obtained laminated glass 1 were measured according to the measurement method prescribed by the above-mentioned Cool Cars Standards. Specifically, the above Tts and the above Tds were measured with a spectrophotometer (“U-4100” manufactured by Hitachi-hitec Co., Ltd.) in accordance with JIS R3106 (1998).

[0121] (2) Determination of visible light transmittance

[0122] The visible light transmittance at a wavelength of 380 to 780 nm of the obtained laminated glass 1 was measured using a spectrophotometer ("U-4100" manufactured by Hitachi-hitec Co., Ltd.) in accordance with JIS R3211 (1998).

Abstract

Disclosed is an intermediate film for a laminated glass, which enables the production of a laminated glass having a low Tts value and high visible light transmittance. Specifically disclosed is an intermediate film (2) for a laminated glass, which comprises a thermoplastic resin, a plasticizer, heat-shielding particles (5), at least one component selected from a phthalocyanine compound, a naphthalocyanine compound and an anthracyanin compound, and a yellow dye. In the intermediate layer (5), the content of the heat-shielding particles is 0.01 to 2 parts by weight and the total content of the component and the yellow dye is 0.25 part by weight or less relative to 100 parts by weight of the thermoplastic resin.

Description

technical field [0001] The present invention relates to an interlayer film for laminated glass used in laminated glass for automobiles, buildings, etc., and more specifically, to an interlayer film for laminated glass capable of improving the heat insulation performance of laminated glass, and an interlayer film using the interlayer film for laminated glass Laminated glass. Background technique [0002] Even if laminated glass is damaged by external impact, the amount of glass shards scattered is very small, and it is excellent in safety. Therefore, the above-mentioned laminated glass has been widely used in automobiles, rail vehicles, airplanes, ships, buildings and the like. The above-mentioned laminated glass is produced by interposing an interlayer film for laminated glass between a pair of glass plates. Laminated glass used in openings of such vehicles and buildings is required to have high heat insulation. [0003] Infrared rays with a wavelength greater than 780nm ...
