Description

上記目的を達成する本発明の転写箔用ポリエステルフィルムは、ポリエステルフィルム（Ｂ層）の少なくとも片面に、下記構造式（Ｉ）で示されるアクリル酸エステルを共重合した化合物からなる塗布層（Ａ層）が形成されてなり、かつ、該塗布層（Ａ層）とは反対側の面を、三次元表面粗さ計で測定したときの算術平均粗さ（ＳＲａ）が３０ｎｍ以下であることを特徴とする転写箔用ポリエステルフィルムである。 The polyester film for transfer foil of the present invention that achieves the above object is a coating layer (A layer) comprising a compound obtained by copolymerizing an acrylate ester represented by the following structural formula (I) on at least one surface of a polyester film (B layer). ) Ri Na is formed, and that the coating layer (a layer) the surface opposite the arithmetic average roughness measured at the three-dimensional surface roughness meter (SRa) is 30nm or less It is the polyester film for transfer foil characterized.

本発明によって作成される転写箔用ポリエステルフィルムは、ポリエステルフィルム（Ｂ層）の少なくとも片面に、下記構造式（Ｉ）で示されるアクリル酸エステルを共重合した化合物からなる塗布層（Ａ層）が形成され、かつ、該塗布層（Ａ層）とは反対側の面を、三次元表面粗さ計で測定したときの算術平均粗さ（ＳＲａ）が３０ｎｍ以下であるため、優れた帯電防止性やオリゴマー析出防止が可能となり、特にインモールド成形に用いられるインモールド転写箔用として使用した場合に、金型汚れや転写ヌケを防止し得る転写箔用ポリエステルフィルムが得られる。 The polyester film for transfer foil prepared according to the present invention has a coating layer (A layer) made of a compound obtained by copolymerizing an acrylate ester represented by the following structural formula (I) on at least one surface of the polyester film (B layer). Since the arithmetic mean roughness (SRa) is 30 nm or less when the surface opposite to the coating layer (A layer) formed is measured with a three-dimensional surface roughness meter , excellent antistatic properties It is possible to prevent precipitation of oligomers, and particularly when used as an in-mold transfer foil used for in-mold molding, it is possible to obtain a polyester film for transfer foil that can prevent mold contamination and transfer leakage.

本発明の転写箔用ポリエステルフィルムは、ポリエステルフィルム（Ｂ層）の少なくとも片面に、下記構造式（Ｉ）で示されるアクリル酸エステルを共重合した化合物からなる塗布層（Ａ層）が形成されてなり、かつ、該塗布層（Ａ層）とは反対側の面を、三次元表面粗さ計で測定したときの算術平均粗さ（ＳＲａ）が３０ｎｍ以下であるものである。 In the polyester film for transfer foil of the present invention, a coating layer (A layer) made of a compound obtained by copolymerizing an acrylate ester represented by the following structural formula (I) is formed on at least one surface of the polyester film (B layer). Do Ri, and the coating layer (a layer) and the opposite face is intended arithmetic average roughness measured at the three-dimensional surface roughness meter (SRa) is 30nm or less.
