Abstract

PROBLEM TO BE SOLVED: To provide the light shielding sheet which sufficiently displays a function for privacy protection day and night and makes people feel bright in the room. SOLUTION: The light shielding sheet 1A is obtained by stacking an adhesive layer 3 on a base material layer 2a and forming a pattern layer 4 on the base layer 2a on the opposite side from the adhesive layer 3. The base material layer 2 is a layer which cuts off light and is formed of a colored film containing a coloring agent 5. The pattern layer 4 has a specific pattern 41 such as a picture pattern, a pattern, and a figure. This pattern 41 has a color higher in lightness than the outward appearance color obtained when the base material layer 2a and adhesive layer 3 are viewed from the side of the pattern layer 4.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a light shielding sheet of the present invention will be described in detail with reference to preferred embodiments shown in the accompanying drawings.

FIG. 1 is a sectional view showing a first embodiment of the light shielding sheet of the present invention. As shown in FIG.
A is obtained by laminating a single-layer base material layer 2a and an adhesive layer 3, and forming a pattern layer 4 on the surface of the base material layer 2a opposite to the adhesive layer 3. Hereinafter, each layer will be sequentially described.

The base layer 2a is a layer having a light-shielding property,
In this embodiment, it is composed of a colored film. That is, the colorant 5 composed of a pigment or a dye is blended (dispersed) in the resin film. In this case, the color of the colorant 5 is preferably a dark color such as black, gray, brown, green, blue, or purple.

As the resin material constituting the base material layer 2a,
Examples thereof include polyester resins such as polyethylene terephthalate and polybutylene terephthalate, polyolefin resins such as polyethylene and polypropylene, polyamide resins, polyimide resins, polycarbonate resins, polyvinyl chloride resins, and the like.

Examples of the colorant 5 include phthalocyanine, azo, azo lake, anthraquinone, perylene, indigo, isoindolinone, dioxazine, quinacridone, aniline black, triphenylmethane, and the like. Organic pigments such as carbon black, inorganic oxides such as titanium oxide, iron oxide, iron hydroxide, chromium oxide, spinel type calcination, chromic acid, chromium vermilion, navy blue, etc., acid dyes, mordant dyes And various pigments and dyes such as basic dyes, direct dyes, sulfur dyes, vat dyes, solubilized vat dyes, azoic dyes, disperse dyes, reactive dyes, dyes such as oxidation dyes and oil-soluble dyes.

Here, the light-shielding properties required for the base material layer 2a and the pressure-sensitive adhesive layer 3 (the portion excluding the pattern layer 4 of the light-shielding sheet 1A) are determined based on their visible light transmittance (JIS A57).
59) is preferably about 3 to 60%.
More preferably, it is about 40%. If the transmittance is too low, the visibility from the room will be poor when the light-shielding sheet 1A is pasted on a window, and if the transmittance is too high, the light-shielding function will be insufficient.

The base material layer 2a is preferably capable of cutting ultraviolet rays by 50% or more.
% Or more is more preferable. Although the thickness of the base material layer 2a is not particularly limited,
200 μm is preferable, and 20 to 100 μm is more preferable.

The pressure-sensitive adhesive layer 3 is mainly composed of a pressure-sensitive adhesive (adhesive composition). The pressure-sensitive adhesive (adhesive composition) may be any of a rubber-based pressure-sensitive adhesive, an acrylic-based pressure-sensitive adhesive, a silicone-based pressure-sensitive adhesive, and a urethane-based pressure-sensitive adhesive. It is preferred that

The acrylic pressure-sensitive adhesive mainly includes a low Tg main monomer component for providing tackiness, a high Tg comonomer component for providing adhesiveness and cohesive strength, and a functional group-containing monomer component for crosslinking and improving adhesiveness. Consisting of a polymer or a copolymer.

Examples of the main monomer component include alkyl acrylates such as ethyl acrylate, butyl acrylate, amyl acrylate, 2-ethylhexyl acrylate, octyl acrylate, cyclohexyl acrylate and benzyl acrylate, and methacrylic acid. Examples thereof include alkyl methacrylates such as butyl, 2-ethylhexyl methacrylate, cyclohexyl methacrylate, and benzyl methacrylate.

Examples include hydroxyl group-containing monomers such as acrylate and N-methylolacrylamide, acrylamide, methacrylamide, and glycidyl methacrylate.

The reason why such a material is preferable is that the polymer is excellent in adhesive strength and cohesive strength, and has high stability to light and oxygen because of no unsaturated bond in the polymer. This is because it is possible to obtain arbitrary quality and characteristics according to the conditions.

Examples of the rubber-based pressure-sensitive adhesive include natural rubber-based, isoprene-based, styrene-butadiene-based, recycled rubber-based, and polyisobutylene-based adhesives, and rubbers such as styrene-isoprene-styrene and styrene-butadiene-styrene. And those mainly comprising a block copolymer containing

Examples of the silicone-based adhesive include dimethylsiloxane-based and diphenylsiloxane-based adhesives.

Examples of the urethane-based pressure-sensitive adhesive include polyether-based and polyester-based pressure-sensitive adhesives.

The pressure-sensitive adhesive layer 3 may exhibit strong adhesion or may have removability. In the former case, there is an advantage that when the light shielding sheet 1A is attached to the window glass, the glass can be prevented from scattering when the window glass is broken. In the latter case, when a problem such as intrusion of air bubbles into the sticking surface occurs when sticking the light shielding sheet 1A, the light shielding sheet 1A can be once peeled off and easily re-attached. (For example, every time the season changes).

In the case of the pressure-sensitive adhesive layer 3 having strong adhesiveness, the adhesive strength (adhesive strength) is preferably from 1,000 to 3,000.
g / 25mm, more preferably 1500-2500g / 25mm
Degree.

It is preferably about 00 μm, more preferably about 10 to 70 μm.

The pressure-sensitive adhesive layer 3 is not limited to being present on the entire surface of the light-shielding sheet 1A, but may be present partially. For example, the pressure-sensitive adhesive layer 3 may be present only at the peripheral portion or the four corners of the light shielding sheet 1A.

Although not shown, a release sheet may be attached to the pressure-sensitive adhesive layer 3.

As the release sheet, any one may be used. For example, films made of various resins such as polyethylene terephthalate, polybutylene terephthalate, polyethylene, polypropylene and polyarylate, polyethylene laminated paper, clay coated paper, Various paper materials, such as glassine paper and recycled paper, may be used as a base material, and a release surface may be applied to a bonding surface of the base material with the adhesive layer 3.

In this case, typical examples of the release treatment include application and formation of a release agent layer composed of a release agent such as a silicone resin, a long-chain alkyl resin, or a fluorine resin.

The pattern layer 4 has a predetermined pattern 41 such as a picture, a pattern or a figure. The pattern 41 is formed of a color having a higher lightness than the appearance color when the base material layer 2a and the pressure-sensitive adhesive layer 3 are viewed from the pattern layer 4 side (upper side in FIG. 1). The color of the pattern 41 includes, for example, relatively bright colors such as white, cream, yellow (lemon), pink, green-white, and blue-white.

The printing method is not particularly limited, and examples thereof include offset printing, intaglio printing, screen printing, relief printing, gravure printing, and flexographic printing.

In such a pattern layer 4, the area ratio of the pattern 41 to the area of the base material layer 2a is:
It is preferably from 30 to 95%, more preferably from 50 to 90%. If the area ratio is too low, the above effects, particularly the privacy protection function, may not be sufficiently exhibited.
Depending on the layer thickness, material, etc. of 1, the function of the window may be partially impaired, for example, the amount of external light taken into the room is extremely reduced.

The pattern 4 constituting the pattern layer 4
1 may be formed by laminating or combining a plurality of materials having various thicknesses, brightness, materials, and the like. The pattern 41 is not limited to a single color pattern, but may be a multicolor pattern.
