Problems solved by technology

[0006] In addition, since metal is used for the above-mentioned heat ray cut glass, there is a problem that the transparency is lowered, or the transmission of electromagnetic waves is blocked, which adversely affects the communication functions of mobile phones, car navigation systems, etc.
In addition, the above-mentioned heat ray cut glass has the problem of becoming expensive due to the use of multi-layer coatings.

Embodiment 1

[0146] 1. Fabrication of heat ray shielding layer

[0147] A composition comprising the following components was coated on a polyethylene terephthalate (PET) film (thickness 100 μm) using an applicator, dried, and passed through a high-pressure mercury lamp at 500 mJ / cm 2 The cumulative amount of light of 200,000 is irradiated with ultraviolet rays to form a heat ray shielding layer (thickness 8 μm) on the PET film.

[0148] (Composition of composition for heat ray shielding layer formation)

[0149] Pentaerythritol triacrylate: 100 parts by mass;

[0150] Photopolymerization initiator (Irgacure 184, manufactured by Ciba Specialty Chemicals Inc.): 4 parts by mass;

[0151] Cs 0.33 WO 3 (average particle diameter 80nm): 30 parts by mass;

[0152] Methyl isobutyl ketone: 100 parts by mass.

[0153] 2. Fabrication of adhesive resin layer

[0154] Using the following formulation as a raw material, a sheet-shaped adhesive resin layer (0.4 mm in thickness) was obtained by cal...

Embodiment 2～8

[0165] In Examples 2-3 and 5-8, except that the compounding quantity of the ultraviolet absorber (1) and the photostabilizer (1) in the adhesive resin layer was changed as shown in Table 1, it carried out similarly to Example 1 Production of heat ray shielding laminated glass.

[0166] In addition, in Example 4, in addition to using 0.2 parts by mass of light stabilizer (2) (bis(1,2,2,6,6-pentamethyl-4-piperidinyl) sebacate; Tinuvin (registered Trademark) 765, manufactured by Ciba Japan K.K.) in place of the light stabilizer (1), a heat ray shielding laminated glass was produced in the same manner as in Example 1.

Abstract

Disclosed is a heat-ray-shielding laminate which is rarely discolored and therefore is rarely deteriorated even when the laminate contains a heat-ray-shielding agent comprising a tungsten oxide. Specifically disclosed is a heat-ray-shielding laminate which is characterized by comprising a heat-ray-shielding layer comprising a tungsten oxide and / or a tungsten oxide complex and at least one adhesive resin layer, wherein the adhesive resin layer comprises an ultraviolet ray absorber, a light stabilizer and an adhesive resin and has a light transmittance of 10% or less at a wavelength of 380 nm.

Description

technical field [0001] The present invention relates to a laminate including a heat ray shielding layer that can be suitably used for laminated glass having excellent impact resistance, penetration resistance, and antitheft properties. Background technique [0002] Generally, glass used in automobiles, especially windshields, uses laminated glass having a structure in which a transparent adhesive resin layer (interlayer film) is sandwiched between glass plates. The adhesive resin layer is formed of, for example, PVB film, EVA film, etc. Due to the presence of the adhesive resin layer, the penetration resistance of the laminated glass is improved. In addition, fragments of broken glass remain attached to the adhesive resin layer in response to external impact, thereby preventing them from scattering. Therefore, for example, even if the laminated glass of an automobile is damaged by theft or break-in, the window cannot be freely opened, and thus is useful as anti-theft glass....
