Manufacturing method for transparent substrate

Abstract

There is provided a manufacturing method for a transparent substrate excellent in bending property, flexibility, impact resistance, and external appearance. A manufacturing method for a transparent substrate according to an embodiment of the present invention includes: a step A of applying a thermoplastic resin (A) composition solution onto a support backing having solvent permeability to form an applied layer; a step B of attaching at least one surface of an inorganic glass and the applied layer to each other via an adhesive composition to form a laminate; a step C of subjecting the laminate to a first heat treatment to reduce an amount of a solvent remaining in the applied layer to a predetermined amount; and a step D including peeling the support backing from the laminate and subjecting the resultant to a second heat treatment to dry the applied layer, thereby forming a thermoplastic resin layer.

1 .- 14 . (canceled) 
     
     
         15 . A laminate, comprising:
 an inorganic glass; and   an applied layer formed by applying a thermoplastic resin (A) composition solution,   wherein;   the thermoplastic resin (A) composition comprises a solvent and a thermoplastic resin (A), and   a amount of the solvent in the applied layer is 3 wt % to 15 wt %.   
     
     
         16 . A laminate according to claim  1 , wherein the laminate is formed by
 applying a thermoplastic resin (A) composition solution onto a support backing having solvent permeability to form an applied layer;   attaching at least one surface of an inorganic glass and the applied layer to each other via an adhesive composition to form a precursor laminate; and   subjecting the precursor laminate to a first heat treatment to reduce an amount of the solvent in the applied layer to a predetermined amount.
