ABSTRACT:
In the transparent film of optical application or the support for photographic material produced by a solution film forming method, the polymer resin film on which any coating unevenness does not occur even when a functional layer is coated on the film surface and the manufacturing method for the film are proposed.To be concrete, a polymer resin film produced by the solution film forming method characterized by that the pitch a [cm] of the periodic thickness unevenness of web longitudinal direction and a thickness unevenness factor d [%] satisfy formula (1) described below.in-line-formulae description="In-line Formulae" end="lead"?d≦0.46a3−0.91a2+0.60a+1.01 (1)in-line-formulae description="In-line Formulae" end="tail"?(on the premise that 0.2<a<3)The manufacturing method using said formula is also proposed.
