Abstract

A continuous multi-layer film includes a support layer having a first film surface, and a hard coat layer, formed on the support layer, having a second film surface, and having a curling tendency in an inward direction. In the decurling method, the multi-layer film is transported. A first transition of the support layer in the multi-layer film being transported into a rubber phase is induced by supplying fluid vapor on the support layer. After supplying the fluid vapor, a second transition of the support layer from the rubber phase into a glass phase is induced. The multi-layer film is transported while a portion of the support layer in the rubber phase is prevented from contacting a solid object. The hard coat layer is formed from a polymer produced from an ultraviolet curable compound, and the support layer is formed from cellulose acylate.
