<p>PURPOSE:To prevent waves in edges and wrinkles in a bound area of pamphlet containing a portrait by applying a coating compsn. containing a hydrophilic binder or resin compsn. containing polyurethan on a paper or cloth substrate to form a binding material. CONSTITUTION:A transparent film is joined with a binding material with a picture recording layer interposed. The binder material is obtd. by applying a coating compsn. containing hydrophilic binder or a resin compsn. containing at least polyurethane on a paper or cloth substrate. Therefore, the obtd. pamphlet has resistance to forgery or modification and maintains rigidity when the laminate film 4 is adhered to the sheet 3 which records the portrait 31. When the transparent laminate film 4 laminated to the recording surface of the portrait 31 is mechanically forced to be peeled, the paper layer is first broken. Thereby, waves in edges and wrinkles in the bound surface can be prevented, and the obtd. pamphlet has good heat resistance.</p> |
