The present invention discloses a display panelhaving a substratewith one or more surfaces and one or more featureswithin the substrate. When electromagnetic radiation is introduced at or directed toward one or more surfaces of the substrate, the featuresredirect the electromagnetic radiation in one or more predetermined directions.

Display panel

The present invention discloses a display panelhaving a substratewith one or more surfaces and one or more featureswithin the substrate. When one or more surfaces of the substrateare illuminated, the featuresredirect the illumination to form an image.

Material having laser induced light redirecting features

Disclosed is a coating formed from a composition containing a film-forming resin and a plurality of particles dispersed in the resin. The average particle size of the particles is 0.1 to 50 microns, and the particles have a hardness sufficient to impart greater mar and/or scratch resistance to the coating as compared to a coating where no particles are present. Also, the difference between the refractive ranges from 1 to 1.5. A method for preparing a powder coating including the particles also is provided.

Coating compositions providing improved mar and scratch resistance and methods of using the same

A process for producing an article having modified optical, chemical, and/or physical properties is disclosed. The process includes (a) fluidizing a starting material; (b) forcing the fluidized starting material toward the article; and (c) passing the fluidized starting material through a high energy zone. The passing step can occur before the forcing step; after the forcing step but before the fluidizing material comes in contact with the surface of the article; and/or after the forcing step and after the fluidized material comes in contact with the surface of the article. The properties of the article are modified because the article has nano-scaled structures distributed on the surface of the article and/or at least partially embedded in the article.

Article having nano-scaled structures and a process for making such article

Provided is a film-forming composition substantially free of organic solvent which includes an aqueous dispersion of polymeric microparticles prepared by emulsion polymerization of a monomeric composition containing (1) at least 10 percent by weight of one or more vinyl aromatic compounds; (2) 0.1 to 10 percent by weight of one or more carboxylic acid functional polymerizable, ethylenically unsaturated monomers; (3) 0 to 10 percent by weight of one or more polymerizable monomers having one or more functional groups capable of reacting to form crosslinks; and (4) one or more polymerizable ethylenically unsaturated monomers. Each of (1), (2), (3) and (4) are different one from the other and at least one of (3) and (4) is present in the monomeric composition. Multi-layer composite coatings and coated substrates also are provided.
