Problems solved by technology

Therefore, when such a material is used as a decorative sheet, the following problems will occur: 1) fine dust will adhere to the printing material roll, which will cause problems such as ink drop-off; Reasons; 3) Due to the adhesion of fine dust, secondary processing is hindered; 4) Even if the fine dust attached is to be removed, it is not easy to remove because it is attached by static electricity, which becomes the main reason for the decrease in productivity and the increase in cost reason
[0006] However, when using these conventional antistatic agents, the following problems can occur: a) sufficient antistatic effect cannot be obtained; b) even if the effect can be ensured, the effect is not sustainable; c) even if the effect is obtained, due to the Stains caused by antistatic agents will impair the appearance of decorative sheets
However, when using a polymer antistatic agent, when the decorative sheet is bent (such as V-shaped cutting), there will be a problem of whitening at the interface between the polymer antistatic agent and polyolefin resin.

Embodiment 1

[0132] produced with figure 2 Decorative flakes of the structure shown.

[0133] (1) Fabrication of a sheet having a polyolefin resin layer

[0134] A colored polypropylene-based resin film 1 (thickness 80 μm) was prepared by adding 10% by weight of a coloring material (titanium oxide), and corona discharge treatment was applied to the outer surface and the back surface. Colored ink gravure printing (full pattern) with a two-component curing type urethane resin as a binder is applied to the outer surface, and a pattern layer of a wood grain pattern is formed thereon with an ink with an acrylic resin as a binder 2. In addition, a primer layer 6 using a polyurethane resin as a binder was formed on the back surface using gravure printing to obtain a printed sheet.

[0135] Next, on the pattern layer 2 of the above-mentioned printed sheet, after forming the adhesive layer 3 made of two-component curing polyurethane resin with a thickness of 15 μm, two layers consisting of the ...

Embodiment 2

[0141] Except having made content of a compatibilizing agent into 10 weight%, it carried out similarly to Example 1, and produced the decorative sheet.

Embodiment 3

[0143] Except that the macromolecular antistatic agent is changed into polyether-ester-amide macromolecular antistatic agent (product name " IRGASTATP18 ", produced by Ciba Specialty Chemicals Inc.), proceed in the same way as in Example 1, and make a decorative sheet .

Abstract

The present invention provides a decorative sheet which contains a polymeric antistatic agent and which is restrained from being whitened when bent.Characteristically, this decorative sheet for being laminated on an adherend comprises at least a polyolefin resin layer, wherein a polymeric antistatic agent and an acid-modified polyolefin resin are contained in the polyolefin resin layer.

Description

technical field [0001] The present invention relates to an antistatic decorative sheet that suppresses whitening when bent. Background technique [0002] Decorative sheets, including various building materials for interior and exterior decoration, are widely used for decoration and surface protection of various home appliances, office machines, measuring instruments, etc. A decorative sheet is generally produced by laminating a printing layer, a synthetic resin layer, a surface protection layer, and the like on a base sheet. Conventionally, vinyl chloride-based resins have been used as synthetic resin layers and the like, but decorative sheets using vinyl chloride-based resins generate toxic gases such as hydrogen chloride gas when burned. Therefore, there is a problem in waste disposal that it cannot be incinerated in a normal incinerator. Moreover, in the event of a fire, it is also a cause of poisoning caused by inhalation of toxic gases such as hydrogen chloride gas. ...
