Title:
ホワイトボードシート
Document Type and Number:
Japanese Patent JP7144900
Kind Code:
B2
Abstract:
To provide a whiteboard sheet excellent in scratch resistance and durability, with further better writing and erasability of a whiteboard marker than a conventional one.SOLUTION: There is provided a whiteboard sheet having a writing layer provided on one surface of a substrate. The writing layer is a hard coat layer formed by applying and drying a coating liquid to the substrate, and then curing it by irradiating it with ionizing radiation, the coating liquid containing a polyfunctional compound polymerized by at least ionizing radiation, and hydrophobic polyfunctional polymeric resin polymerized by ionizing radiation. A content ratio of the hydrophobic polyfunctional polymeric resin polymerized by ionizing radiation in a solid content of the writing layer is 0.1 to 8 wt.%, and a content ratio of the polyfunctional compound polymerized by ionizing radiation and the hydrophobic polyfunctional polymer resin polymerized by ionizing radiation in the solid content of the writing layer is 70 wt.% or more.SELECTED DRAWING: None
