Embodiment

[0301] Hereinafter, the present invention will be more specifically described using Preparation Examples, Production Examples, Examples, Comparative Examples, and Test Examples. Materials, usage amounts, ratios, operations, and the like shown below can be appropriately changed without departing from the spirit of the present invention. Therefore, the scope of the present invention is not limited to the specific examples shown below.

[0302] Table 1 summarizes the thermoplastic resin compositions used in the production examples of the resin film layer (A) and the resin film layer (B) of the present invention. For these compositions, the resin compositions (a) to (f) prepared by mixing the raw materials described in Table 1 in advance in the ratio described in Table 1 were melt-kneaded with a twin-screw kneader set at 210°C. kneading, then extrude in strands with an extruder set at 230°C, and after cooling, cut off with a strand cutter to make pellets of resin compositions (a)...

Abstract

This electrostatically adsorptive sheet (iii) is obtained by laminating an adsorptive sheet (i) which comprises a resin film layer (A) that is provided with an adhesive layer (C) on one surface, and a supporting layer (ii) which comprises a resin film layer (B). The resin film layer (A) of the adsorptive sheet (i) and the resin film layer (B) of the supporting layer (ii) are bonded with each other by electrostatic adsorption.

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. It is possible to write on a stationery using water-based or oil-based ink like a whiteboard, and the notes can be easily erased. [0002] Since the electrostatic adsorption sheet has electrostatic adsorption ability, it can be used to bond printed matter or a resin film containing fluororesin to the adherend, and it is difficult to generate air entrapment between the sheet and the adherend , Printed matter or resin film containing fluororesin can be placed on the adherend for a long time, and can be used for display. [0003] In addition, the electrostatic adsorption sheet is light in weight and easy to carry, and can be easily peeled off and separated from the adherend after use, and can be attached again. Background technique [0004] Conventionally, as a display that has been pri...
