PROBLEM TO BE SOLVED: To provide postcard paper on which an address surface is superior in offset printability, whereas, on a communication surface, seeping arises suited for drawing with Chinese ink, watercolors or the like and furthermore a curl hardly occurs after drawing with the Chinese ink, the watercolors or the like.SOLUTION: Provided is multilayer postcard paper which uses pulp as a principal component and consists of at least three layers including a surface layer, a back layer, and at least one middle layer between the surface layer and the back layer. The multilayer postcard paper has a basis weight of 200-350 g/m, a thickness of 0.35-0.50 mm, and a density of 0.6-0.75 g/cm, and only the surface layer and the middle layer contain a paper strengthening agent and a sizing agent while the back layer does not contain the paper strengthening agent nor the sizing agent. |
