Abstract
Provided is a manufacturing method for a multilayer laminated film at a high coating rate, whereby film thickness uniformity is improved and interference unevenness is reduced. The present invention is a manufacturing method for a multilayer laminated film, the method including the step of simultaneous multilayer coating of plural coating liquids onto a substrate at a coating rate of 10 m/min or more, wherein, when A [mPa·s] stands for the viscosity of the coating liquid at a temperature of 45° C. and a shear rate of 10 sec, B [mPa·s] stands for the viscosity of the coating liquid at a temperature of 45° C. and a shear rate of 1000 sec, and C [mPa·s] stands for the viscosity of the coating liquid at a temperature of 45° C. and a shear rate of 10000 sec, at least one coating liquid of the plural coating liquids has A/B in the range of 1.5 to 9 and B/C in the range of 0.6 to 1.4.
