Problems solved by technology

[0004] Although this method has the advantages that the adhesive surface can also display printing, etc., it also has the following disadvantages: when it is attached to an adherend such as a glass plate, it is easy to partially retain air between the adherend and the adhesive, and The aesthetics of the printed matter with the adherend deteriorates

Embodiment

[0201] [Evaluation method]

[0202] (thickness)

[0203] The thickness in the present invention is measured in accordance with JIS-K-7130 using a constant pressure thickness measuring device (manufactured by TECLOCK Corporation, trade name: PG-01J).

[0204] When the formed thermoplastic resin film has a multilayer structure, the thickness of each layer is obtained as follows: the sample to be measured is cooled to a temperature below -60° C. with liquid nitrogen, Name: ProlineBlade) vertically cut the sample placed on the glass plate to prepare a sample for cross-section measurement, and the obtained sample was analyzed using a scanning electron microscope (manufactured by JEOL Ltd., trade name: JSM-6490). The cross-sectional observation was carried out to determine the boundary line of each thermoplastic resin composition from the appearance of the composition, and the thickness of each layer was obtained by multiplying the thickness of the entire thermoplastic resin film b...

preparation example

[0218] Each component constituting the coating layer (C) used in the following examples and comparative examples was prepared in the following procedure.

[0219] [Preparation example of polymer (i) having antistatic function]

[0220] 100 parts by mass of polyethylene glycol monomethacrylate (manufactured by NOF Corporation, trade name: BLEMMERPE-350), 20 parts by mass of lithium perchlorate (manufactured by Wako Pure Chemical Industries, Ltd., reagent), terephthalate 1 part by mass of phenol (manufactured by Wako Pure Chemical Industries, Ltd., reagent) and 400 parts by mass of propylene glycol monoethyl ether (manufactured by Wako Pure Chemical Industries, Ltd., reagent) were introduced. In a four-necked flask with a liquid funnel, the system was replaced with nitrogen, and the reaction was carried out at 60° C. for 40 hours. To this reaction product, 5 parts by mass of stearyl methacrylate (manufactured by Wako Pure Chemical Industries, Ltd., reagent), 5 parts by mass of ...

preparation example 1

[0231] At room temperature, while stirring the methyl ethyl ketone gently with a Cowles mixer, add the pigment particles recorded in Table 1 measured separately to it little by little, and after adjusting the solid content concentration to 20% by mass, raise the Cowles mixer. The speed of rotation was stirred for 30 minutes to prepare a pigment dispersion.

[0232] Next, reduce the rotational speed of the Cowles agitator, and add the polymer binder (iii) solution described in the above preparation example, the polymeric binder (iii) with antistatic function to the pigment dispersion in the mixing ratio described in Table 1 The solution of the substance (i) and the solution of the curing agent described in Table 1 (diluted with ethyl acetate to a solid content of 20% by mass) was stirred and mixed for 20 minutes in this state, and then passed through a 100mesh filter Then, the removal of the coarse particle diameter was performed, and methyl ethyl ketone was added to this solut...

Abstract

Double-faced adhesive sheets are provided with each of which a printed matter having no pressure-sensitive adhesiveness, e.g., an advertising leaflet, can be applied to and displayed on an adherend without requiring the use of a pressure-sensitive adhesive or the like. When the printed matter is applied to the adherend, air bubbles are less apt to remain. One of the double-faced adhesive sheets is an electrostatically fixable sheet which comprises: a support layer (A) comprising a thermoplastic resin film that has undergone a charging treatment; and a protective layer (B) which comprises a dielectric film and has been laminated to at least one surface of the support layer (A) by electrostatic attraction. Another is an electrostatically fixable sheet which comprises: a support layer (A) comprising a thermoplastic resin film; and a protective layer (B) which comprises a dielectric film that has undergone a charging treatment and which has been laminated to at least one surface of the support layer (A) by electrostatic attraction.

Description

technical field [0001] The present invention relates to an electrostatic adsorption sheet, which can easily adhere non-adhesive printed matter such as signboards, posters, advertisements, etc. to an adherend by utilizing electrostatic adsorption without using adhesives or adhesives. Background technique [0002] Conventionally, in order to produce a display sheet product with good releasability, a special sheet obtained by pre-coating an adhesive with good releasability on one side of the display sheet is used, and The text and patterns to be displayed are printed on the other side. The adhesive in this special sheet sometimes tends to ooze out from the end surface. Therefore, in the subsequent printing process and cutting process, it is easy to cause the adhesive to adhere to the machine, other failures of the display sheet, etc., which reduces the work efficiency. . In addition, since the display sheet is provided with an adhesive in advance, there is a disadvantage that...
