Flexible film

The present invention relates to a flexible film, more specifically, to a flexible film that not only exhibits high hardness, but also has excellent flexibility. According to the flexible film of the present invention, flexibility, bendability, high hardness, scratch resistance, and high transparency are exhibited, and there is no concern for damage of the film even when bended repeatedly or folded for a long time, and thus, it may be usefully applied for the front panels, display parts of bendable, flexible, rollable, or foldable mobile devices, display devices, various instrument panels, and the like.

COMPOSITION AND ARTICLE COMPRISING THE SAME

Uncured aqueous composition comprising a blend of (a) a sulfonated polyester, (b) at least one of a self-crosslinking acrylic or a self-crosslinking polyurethane binder, and (c) melamine-formaldehyde crosslinker, wherein the uncured aqueous composition has a free-formaldehyde content not greater than 0.04 part per million formaldehyde as determined by the Formaldehyde Test, and cured composition thereof. Compositions described herein are useful, for example, for making primed film for release liners applications.
