发明名称 SHEET FOR WRITING BOARD AND REFLECTION TYPE SCREEN
摘要 There is provided a sheet for a writing board and a reflection type screen having excellent writability and erasability when used as a writing board and having excellent anti-glare property when used as a reflection type screen without generation of hot spots. This sheet for a writing board and a reflection type screen is provided with a resin layer on at least one surface of a substrate on which a user can write with a writing board pen and erase the writing, and unevenness having an arithmetical mean deviation (JIS-B-0601) of 1.0-4.0 .mu.m and a mean spacing of profile irregularities (JIS-B-0601) between adjacent protruded portions of 30-300 .mu.m is formed on the resin layer by embossing. The resin layer preferably contains an ionizing radiation curable resin such as an ultraviolet ray curable resin. Since the unevenness is formed on the resin layer by embossing, an ink is not soaked in the layer and hence this sheet has excellent erasability as a writing board.
