Patent ID: 10392486

Abstract:
A coat layer and a substrate layer are combined to prepare a transparent laminate film; the coat layer has a surface with a maximum height of rolling circle waviness profile (WEM) in accordance with JIS B0610 of 5 to 15 μm and an arithmetic average roughness (Ra) of not less than 0.5 μm. The transparent laminate film provides a comfortable writing experience and a reduced abrasion of a pen tip. The coat layer may have the surface with the arithmetic average roughness (Ra) of 0.5 to 5 μm. The coat layer may contain particles and a binder component. The binder component may comprise a polyfunctional (meth)acrylate, and a urethane (meth)acrylate and/or a thermoplastic elastomer. The transparent laminate film may have a total light transmittance of not less than 85%. The transparent laminate film may be disposed on a surface of a display of a pen-input device.
