Description

  The present invention relates to a method for producing a sheet having a fine concavo-convex pattern.

  A lot of plastics are used in automobile interior parts for the purpose of weight reduction and mass production, and the surface of interior parts made of the plastics is subjected to texture processing to create a sense of quality and weight. Has been. The interior parts that have been subjected to the texture processing and the like can be easily manufactured (mass-produced) by producing a mold in advance.

  However, it is a problem in terms of time and cost to manufacture molds for all interior parts at the stage of a prototype vehicle for exhibition at a motor show or catalog production.

  Therefore, conventionally, the photosensitive resin film is exposed with a negative film having a through-hole portion and a light-shielding portion, and the exposed photosensitive film is bonded to the surface of the interior product of the prototype vehicle. There has been proposed a method in which an unexposed portion of a film is removed to form a convex pattern on the surface of a product, and coating is further performed on the convex pattern (Japanese Patent No. 3401463).
