Abstract (en)

[origin: EP0426863A1] This invention relates to a post card including a post card base sheet and a bonded material which is bonded to at least part of the post card base sheet. The bonded material includes a sheet base material having a shielding property, a first heat-bondable resin layer formed on one of the main planes of the sheet base material and having low bonding power and a second heat-bondable resin layer formed at part of the surface of the first heat-bondable resin layer and having high bonding power, and is bonded to the surface of the post card base sheet by the first and second heat-bondable resin layers. The first heat-bondable resin layer is weakly bonded to the post card base sheet and the second heat-bondable resin layer, strongly. Accordingly, the sheet substrate will not by any chance peel off from the post card base sheet due to the force acting on the portion where the second heat-bondable resin layer is formed. When the sheet base material or the like is cut and peeled at the portion where the second heat-bondable resin layer is not formed, the first heat-bondable resin layer is peeled off from the post card base sheet along with the sheet base material in the case of a post card including the sheet base material having the shielding property and on the other hand, the shielding layer and the first heat-bondable resin layer are peeled off from the post card base sheet along with the sheet base material in the case of a post card including the shielding layer having the shielding property. Accordingly, the surface of the base sheet of the post card becomes visible. Thus the present invention provides a post card capable of shielding suitably and temporarily the indicated items on the surface of the post card base sheet without applying any machining or treatment to the surface of the post card base sheet, and a method of its production.
