发明名称 SHEET HAVING UNEVEN PATTERN FORMED THEREON AND METHOD FOR MANUFACTURING THE SAME
摘要 <p>Disclosed is a sheet having an uneven pattern formed thereon, which comprises a base material comprising a resin and a hard layer formed on one surface of the base material and comprising a resin, wherein an uneven pattern is formed on the surface of the hard layer. In the sheet, the difference between the glass transition temperature (Tg<SUB>2</SUB>) of the resin constituting the hard layer and the glass transition temperature (Tg<SUB>1</SUB>) of the resin constituting the base material (Tg<SUB>2</SUB> - Tg<SUB>1</SUB>) is 10°C or more, and the average depth of the bottoms of the uneven pattern is 10% or more when the modal pitch is set as 100%. Also disclosed is a method for producing the sheet.</p>
