The present invention relates to a method of preparing a hierarchical surface. The method comprises applying a first formulation comprising particles with a median particle diameter, D.sub.50, in the range of from 1 nm to 450 nm and a polymeric binder to a substrate, and then applying a second formulation comprising particles with a median particle diameter D.sub.50 in the range of from 500 nm to 1000 m on top of the first formulation. The particles self-assemble to provide a robust hierarchical structured surface. The particles can be functionalised to introduce functionalities, such as anti-viral functionality, which present at the surface. The method can be used to prepare robust, hydrophobic or super-hydrophobic anti-viral surfaces.

A hard coating film containing a polymer nanoparticle (A) and a matrix component (B), wherein a Martens hardness HM.sub.A of the polymer nanoparticle (A) and a Martens hardness HM.sub.B of the matrix component (B) satisfy a relationship of HM.sub.B/HM.sub.A>1, and a Martens hardness HM of the hard coating film is 100 N/mm.sup.2 or more.

The present invention relates to a decorative, or security element and a method for producing the decorative, or security element. The decorative, or security element comprises in this order (a) a substrate; (b) a coating, comprising transition metal particles (A) having a number mean diameter of from 15 nm to 700 nm, wherein the transition metal is selected from silver, copper, gold and palladium, especially silver and copper, very especially silver; (c) optionally a protective coating; wherein the coating (b) is derived from (b1) a solvent based composition, comprising the transition metal particles and a vehicle; and (b2) the coating (b) has a three layer structure: (b2a) a layer, comprising the transition metal particles and a vehicle; (b2b) a layer, comprising the vehicle, which is essentially free of transition metal particles; (b2c) a layer, comprising the transition metal particles and the vehicle. The method comprises the steps of i) applying a solvent based composition comprising transition metal particles and the vehicle; on at least part of the surface of the substrate, and ii) drying the solvent based composition; iii) curing the solvent based composition so as to form the three-layer structure which exhibits intensive angle-dependent colors in reflection on the coating side and/or on the substrate side of the decorative, or security element and a distinctive color in transmission; and iii) optionally applying a protective coating on the coating (b). The three-layer structure exhibits intensive angle-dependent colors in reflection on the coating side and, optionally, on the substrate side, due to thin-film interference in a Fabry-Perot resonator structure, which is produced in one coating or printing step.
