A formulation may include at least one of an ultraviolet (UV)/visible (VIS) absorbing (UAC) component and a UV/VIS reflective (URC) component.

In various embodiments, the present invention is directed to a supraparticle for use in producing structural colors comprising a plurality of core/shell nanoparticles having a melanin or synthetic melanin core and a silica shell having a plurality of silanol groups on its outer surface and a poly(ethylene glycol) (PEG) crosslinker. In various embodiments, the structure of these these crosslinked supra particles is reinforced by hydrogen bonds formed between the silanol groups on the core-shell nanoparticles and mechanical, solution phase, and dry state stability.

Disclosed herein is a method of preparing a multilayer coating system on a substrate including a step of applying at least one organic black pigment containing basecoat composition to a substrate and forming a first coating film thereon (1), optionally subsequently applying a second basecoat composition and forming a second coating film adjacent to the first coating film (2), and applying a pigmented topcoat composition to the first coating film in case optional step (2) is not performed (3a), or applying a clearcoat composition to the second coating film in case optional step (2) is performed, and where steps (1), (2) and (3b) are performed, or steps (1) and (3a) are performed, includes at least one non-black coloring pigment having a volume average particle size of <1000 nm in an amount in the range of from 0.01 to 7.50 wt.-%, based on its total solid content.

A multi-layered multifunctional polymeric latex article is provided. A first polymeric latex layer, having nitrile butadiene, is resistant to chemical permeation whilst the second polymeric latex layer disposed on the first layer, being a composite layer of polychloroprene and Nano clay, is resistant to chemical degradation. The third layer disposed on the second layer is a polychloroprene layer having a unique micro-roughened surface texture pattern, providing an improved grip and friction in both wet and dry conditions. The second and third layers are disposed during the wet gelled stages of the first and second layers respectively. The gelled third layer is dipped in a solvent mixture whereby a chemical reaction causes the gelled surface of the third layer to texturize by swelling and fixing, creating a continuous and discontinuous wavy micro-roughened surface which is then cured causing formation of ionic crosslinks in the third polymeric layer.
