A process for producing a resin substrate having a hard coating layer on at least one side of a resin substrate, comprising, in the following order, a step of applying a hard coating composition containing an organopolysiloxane to at least one side of the resin substrate to form a coating film of the composition, and then applying a first heat treatment to the coating film to form a cured film; an irradiation step of applying a Xe 2 excimer light irradiation treatment to the cured film in an atmosphere having an oxygen concentration of at most 5 vol %; and a step of applying an oxidation treatment to the cured film obtained by the irradiation step and then further applying a second heat treatment to form the hard coating layer. |
