Abstract:
1. A method for producing a microparticle-laminated thin film-attached substrate in which a microparticle-laminated thin film having voids is formed on a plastic substrate, the method comprising: (A) having a plastic substrate having a coefficient of thermal expansion of 50 to 350 (ppm/K), brought into contact with or coated thereon with any of an electrolyte polymer solution and a microparticle dispersion liquid; (B) having the plastic substrate obtained after the contact or coating with the electrolyte polymer solution, brought into contact with or coated thereon with a dispersion liquid of microparticles having a charge opposite to that of an electrolyte polymer of the electrolyte polymer solution, or having the plastic substrate obtained after the contact or coating with the microparticle dispersion liquid, brought into contact with or coated thereon with a solution of an electrolyte polymer having a charge opposite to that of microparticles of the microparticle dispersion liquid; and (C) binding microparticles of the microparticle dispersion liquid and adhering the microparticle-laminated thin film obtained after the contact or coating with the electrolyte polymer solution or the microparticles to the plastic substrate by filling voids within the microparticle-laminated thin film with an applied alcoholic silica sol product.
