Document Type and Number:
WIPO Patent Application WO/2014/054703
Kind Code:
A1
Abstract:
A structure having irregularities on the surface thereof, wherein the irregularities are formed as the result of the self-organization of a polyimide or the like. The structure can be produced by a method comprising an application step of applying a composition for structure formation purposes onto a base, a leaving step of allowing the applied product to be left subsequent to the application step, and a firing step of firing the resultant product subsequent to the leaving step, wherein the composition comprises the following components (A) and (B): (A) a first polymer comprising a polyimide or a first polymer precursor comprising a polyimide precursor; and (B) a second polymer or a second polymer precursor which is different from the component (A) and/or propylene glycol monomethyl ether.
