Abstract:
A process for producing a composite substrate material, comprising the steps of:i) overlaying, on a surface of each of at least two substrate materials, a bonding film which is capable of generating photo-catalytic effects and causing a super-hydrophilic state to occur on said surface, ii) exposing the bonding film, which has been overlaid on the surface of each of the at least two substrate materials, to light having a wavelength falling within an absorption wavelength range of the bonding film to generate said photo-catalytic effects and to cause said super-hydrophilic state to occur on the surface, and iii) bonding the at least two substrate materials to each other with the functional films, which have been exposed to the light, wherein the bonding films are positioned between the at least two substrate materials.
