Abstract: A method for manufacturing a sheet having a fine shape transferred thereon, in which a sheet-like base made of a thermoplastic resin is placed between an imprint mold and an intermediate base and the sheet-like base is then pressed by a pair of pressing plates to imprint the fine shape of surface irregularity of the imprint mold to the sheet-like base. The sheet-like base is pressed such that, when pressing force of the pressing plates is maximum, an imprinting pressure difference is present in an imprinting surface of the imprint mold, a maximum imprinting pressure section is present in the imprinting surface, and a portion where the imprinting pressure is minimum is not present in the imprinting surface. The method achieves uniform and highly accurate shape transfer without trapping of air.
Abstract translation: 一种制造转印有微细形状的片材的方法，其中将由热塑性树脂制成的片状基底放置在压印模具和中间基底之间，然后将片状基底用一对压板 将压印模具的表面不规则的细小形状压印到片状基底。 片状基底被按压使得当压板的按压力最大时，在压印模具的压印表面上存在压印压力差，在压印表面中存在最大压印部分，并且部分 压印压力最小的部分不存在于压印表面。 该方法实现均匀且高精度的形状传递，而不会捕获空气。
