Field of the Invention The present invention relates to a concealment sheet for concealing confidential information by attaching the confidential information to a surface on which the confidential information is written, and a method of manufacturing the concealing sheet.

[0002]

2. Description of the Related Art For example, when a "fund transfer application form" for assuring that payment of a membership fee or fee is periodically made from a financial institution account is a postcard, the financial institution name and account number serving as confidential information are used. , Notification stamps, etc. are typical ones that you do not want others to know.

FIG. 1 shows a sheet provided with a concealing sheet of the present invention. The prior art will be described with reference to FIG.
The paper 1 is an “fund transfer application form”, one of which is formed on the application form paper 3 and the other is formed on the concealing sheet 4 by a folding line 2 having a perforated structure. Here, the application form 3 is formed in the same size as the postcard, but the length of the short side of the concealment sheet 4 is slightly shorter than the short side of the application form 3.

Although not shown, the back side of the application form 3 is the front side of the postcard, and the address, name, "postcard" and the like of the recipient are described.

As shown in FIG. 1B, the cross-sectional structure of the concealing sheet 4 is such that a resin film 11 is adhered to a sheet mount 10 with a first adhesive 12, and a nonwoven fabric 13 is thermally adhered to the resin film 11 so as to be peelable. ing. In addition, non-woven fabric 13
A second adhesive 14 is applied to the other side of the second adhesive 1
A release paper 15 coated with a release agent 16 such as silicon on the other surface of the substrate 4 is releasably bonded.

In the above structure, the resin film 11 and the nonwoven fabric 13 and the nonwoven fabric 13 and the release paper 15 are releasably bonded once peeled off once, but are peelably bonded. However, since the adhesive strength between the resin film 11 and the nonwoven fabric 13 is larger than the adhesive strength between the release paper 15 and the nonwoven fabric 13, the adhesive strength between the release film 15 and the nonwoven fabric 13 is normal. When peeled, only the release paper 15 is peeled off.

On the other hand, on the application form 3, after describing the applicant's address, name, financial institution name, account number, notification stamp, and other necessary items, the release paper 15 of the concealment sheet 4 is peeled off, and The concealment sheet 4 is folded and attached to the application form 3. As a result, the confidential information described on the application form 3 is concealed by the concealment sheet 4, so that even if the application form 3 is used as a postcard, the application form 3
There is no risk that the confidential information described in (1) is known to a third party.

Incidentally, when the recipient of the application form 3 peels off the concealing sheet 4 from the application form 3, the adhesive surface between the resin film 11 and the nonwoven fabric 13 is peeled off. That is, the nonwoven fabric 13 remains on the application form 3 and the concealing sheet 4 (sheet mount 10) is discarded with the resin film 11 attached thereto.

In the prior art, the operation of peeling the release paper 15 was not easy because the release paper 15 serving as the separator was formed to be the same size as the other materials laminated on the lower surface thereof. Further, if the corners of the release paper 15 are to be caused by a nail or the like to forcefully peel off, the surface of the nonwoven fabric 13 and the resin film 11 may be peeled off. There was a problem that it was not possible to affix properly.
