- Japanese Patent Application Laid-Open No. Hei 59-39595 discloses a method using a pressure-sensitive adhesive or an adhesive obtained by adding fine silica to a light-sensitive adhesive, after bonding the inner surfaces to each other. According to the publication of Japanese Patent Application Laid-Open Publication No. 2000-852701, the visibility of printed characters after peeling and opening is improved by using silica whose optical refractive index and particle size are specified. Or to solve the problem.
- Japanese Patent Application Laid-Open No. 2000-202974 proposes to apply an adhesive comprising a mixture of biel acetate Zacryl copolymer emulsion and epoxy emulsion to a sheet in an undried state; I have.
- the concealed postcard manufactured by this method has a problem that it does not adhere to the adhesive layer at the time of opening when the concealed postcard does not reattach at room temperature. No. 2000-190668).
- the peeled substrates of the concealed postcards re-attach at room temperature when the same pressure is applied as in the pressure-sensitive bonding with the pressure-sensitive adhesive. For this reason, even if a third party other than the recipient opens and reattaches the postcard and the recipient receives it, the recipient has already opened the personal information and leaked personal information to the third party There is a danger of receiving the postcard without knowing that, and it will not fulfill the role of maintaining the confidentiality of the personal information possessed by the confidential postcard. Further, in this postcard, the material of the base material was destroyed when the sheets were peeled off from each other, and the printed and printed information medium was lost, and the visibility was sometimes reduced. Disclosure of the invention
