Abstract
(EN)
Provided is a thread material that is to be provided in forgery prevention sheets and comprises reflective polarizers and a first base film formed of a resin. The in-plane retardation of the first base film at a 590 nm measurement wavelength is not more than 10 nm, and the retardation in the thickness direction of the first base film at the 590 nm measurement wavelength is -10 nm to 10 nm.
(FR)
L'invention concerne un matériau de fil qui doit être fourni dans des feuilles de prévention de falsification et qui comprend des polariseurs réfléchissants et un premier film de base formé d'une résine. Le retard dans le plan du premier film de base à une longueur d'onde de mesure de 590 nm n'est pas supérieur à 10 nm, et le retard dans le sens de l'épaisseur du premier film de base à la longueur d'onde de mesure de 590 nm est de -10 nm à 10 nm.
(JA)
偽造防止用紙に設けるためのスレッド材であって、スレッド材が樹脂で形成された第一基材フィルムと反射偏光子とを備え、測定波長590nmにおける第一基材フィルムの面内レターデーションが10nm以下であり、測定波長590nmにおける第一基材フィルムの厚み方向のレターデーションが-10nm以上10nm以下である、スレッド材。
