Abstract
The present invention addresses the problem of providing a structure which comprises metal plate microparticles and a lipophilic clay-based intercalation compound and which exhibits excellent stability. The problem is solved by a structure as described above wherein: the metal plate microparticles are platy microparticles alone or a mixture thereof with polyhedral microparticles (including spherical microparticles); the platy microparticles have a thickness of 1 to 50 nm, a length of principal plate of 10 to 5000 nm and an aspect ratio thereof of 3 or more; and the weight ratio of the lipophilic clay-based intercalation compound to the metal plate microparticles is 0.01 to 50.
Claims12
