<P>PROBLEM TO BE SOLVED: To provide a resin sheet of which surface is subjected to an emboss processing and which causes difficultly a color tone in a roll edge face when the resin sheet is wound in a roll shape. <P>SOLUTION: This resin sheet is produced from a synthetic resin in which on one side thereof, a large number of convex portions in a substantially pyramid shape are formed by an emboss processing, in which the total light transmittance of incident lights entering through the emboss-processed face which is measured by a spectrophotometer equipped with an integrating sphere is in a range of 75-78% and the 5° specular reflectivity of the emboss-processed face which is measured by a spectrophotometer is in a range of 0.4-0.5%. <P>COPYRIGHT: (C)2012,JPO&INPIT |
