REFLECTION MIRROR FOR ROAD AND MANUFACTURING METHOD OF REFLECTION MIRROR FOR ROAD

摘要

PROBLEM TO BE SOLVED: To provide a reflection mirror for a road and a manufacturing method thereof, for forming a synthetic resin base material surface in an excellent state.SOLUTION: A reflection mirror comprises a reverse surface reflection type mirror body having a transparent base material, a reflection layer formed on a reverse surface of this base material and a hydrophilic antifouling layer formed on a surface of the base material, and the base material is molded in a state of heating and softening a plate material composed of a thermoplastic resin, and the antifouling layer is formed by imparting a hydrophilic material for constituting the antifouling layer in a state of swelling or partially melting a surface of the base material by a solvent. Since the hydrophilic material is imparted by swelling or partially melting the surface of the thermally molded base material by the solvent, a flaw and strain of the base material surface caused by thermal molding are reduced by being restored by swelling and partial melting of the base material, and a surface of the mirror body is formed in an excellent state.
