Abstract
A method for producing a functional film having at least one functional layer comprising a compressed layer of functional particles on a support, in which the method comprises applying a liquid in which the functional particles are dispersed onto a transfer support and drying the liquid to form a transfer precursor film having a layer containing the functional particles formed on the transfer support; superposing the support on which the functional layer is to be formed and the transfer precursor film so that the support and the layer containing the functional particles are brought into contact with each other, and compressing the layer containing the functional particles to form the compressed layer of the functional particles on the support; and thereafter releasing the transfer support from the compressed layer of the functional particles.
