<P>PROBLEM TO BE SOLVED: To provide a hard coat film that is excellent in blocking resistance and clarity. <P>SOLUTION: The manufacturing method for a hard coat film comprises applying a resin composition on a substrate film and subsequently drying it to form a hard coat layer, wherein a period for drying the resin composition at a temperature where the viscosity of a resin in the resin composition applied on the substrate film falls within the range of 3-7 mPa s is introduced in a decreasing drying section in the drying step. The length of the period is designed so that 1.5 V≤t≤4.5 V is satisfied, where t (sec) is the length of the period and V is the volume (cm<SP POS="POST">3</SP>/m<SP POS="POST">2</SP>) of the resin in the resin composition applied on 1 m<SP POS="POST">2</SP>of the substrate film. <P>COPYRIGHT: (C)2012,JPO&INPIT |
