Manufacturing method for transparent substrate

摘要

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. A manufacturing method for a transparent substrate, comprising:
a step A of applying a thermoplastic resin (A) composition solution onto a support backing having solvent permeability to form an applied layer; wherein the thermoplastic resin (A) composition solution comprises a solvent and a thermoplastic resin (A); then 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; then a step C of subjecting the laminate to a first heat treatment to reduce an amount of the solvent to a predetermined amount; and then a step D of peeling the support backing from the laminate and then subjecting the resultant to a second heat treatment to dry the applied layer, thereby forming a thermoplastic resin layer, wherein the adhesive composition comprises a solvent, and the solvent in the adhesive composition exhibits the property of dissolving thermoplastic resin (A) contained in the thermoplastic resin (A) composition solution.
