A laminate comprising a plastic substrate (A); a hardened organic polymer layer (B) provided on a surface of the plastic substrate (A) and having a storage elastic modulus of from 0.01 to 5 GPa and tan &#x3b4; of from 0.1 to 2.0 at 25&#xb0; C. which are measured at a temperature elevating rate of 2&#xb0; C./min by a dynamic viscoelasticity test stipulated in JIS K 7244; an organic/inorganic composite layer (C) provided on a surface of the hardened organic polymer layer (B) and containing covalently bound organic polymer and metal oxide nanoparticles; and an inorganic layer (D) provided on a surface of the organic/inorganic composite layer (C) and comprising secondary particles of ceramic or metal.

Laminate and method of producing same

A layered structure having high adhesive properties, and high hardness or excellent transparency, is prepared on a base material such as a resin. A layered structure including: an organic-inorganic hybrid member containing a primary inorganic particle and an organic polymer covalently bound to each other, wherein the primary inorganic particle forms a network containing the polymer; and a particle aggregate layer containing a secondary particle which is deposited on the organic-inorganic hybrid member and is composed of an inorganic material or a metallic material; wherein in the organic-inorganic hybrid member, the primary inorganic particle and the secondary particle have different crystal particle sizes.
