Opitical article and process for producing the same

A process for producing an optical article having a plurality of light transmissive members, an optical functional film interposed between the light transmissive members, and a bonding layer that bonds a surface of the optical functional film to a surface of the light transmissive member, comprising:

• an optical functional film forming step of alternately forming a low refractive index layer having a low refractive index and a high refractive index layer having a high refractive index on a surface of at least one of the plurality of light transmissive members, with the proviso that the outermost layer is formed of a high refractive index layer;
• a bonding layer forming step of forming a plasma-polymerized film having the same refractive index as that of the low refractive index layer on a surface of at least one of the plurality of light transmissive members and the optical functional film;
• a surface activating step of activating the plasma-polymerized film formed in the bonding layer forming step;
• and
• a bonding step of bonding the plurality of light transmissive members, the optical functional film, and the plasma-polymerized film to one another by interposing the optical functional film and the plasma-polymerized film between the light transmissive members.
