System and method for making a film having a matte finish

摘要

A system and a method for providing a film having a matte finish is described. A coatable material is applied to a substrate. The viscosity of the coatable material is changed and a face-side roller having patterned features thereon contacts the coatable material to impart a matte finish thereon; and hardening the coatable material.

1. A method of producing a textured film comprising:
applying a first coatable material to a first major surface of a substrate such that the coatable material has a first major surface in contact with the first major surface of the substrate and a second major surface opposite the first major surface of the first coatable material; changing the viscosity of the first coatable material from a first viscosity to a second viscosity to form a second coatable material; contacting the second coatable material to a face-side roller having patterned features thereon; splitting the second coatable material from the face-side roller having patterned features thereon to form a textured surface wherein a first volume of the second coatable material adheres to the face-side roller and a second volume of the second coatable material is released from the face-side roller back onto the first major surface of the substrate; wherein the second volume of the second coatable material is released from the face-side roller at a rate that is the same rate at steady-state or nearly the same rate as the first volume of the second coatable material is adhered to the face-side roller, and wherein the textured surface is not a mirror image of the surface of the face-side roller having patterned features thereon; and, hardening the second coatable material of the textured surface to produce a resultant film substrate with a resultant textured surface.
