A powder coating material contains an acrylic resin that has a side chain having an alkyl group having 4 or more carbon atoms and a hydroxy group; and a curing agent.

Provided by the present inventions are a pattern-printed sheet and a method for manufacturing this, wherein the pattern-printed sheet is characterized that on a precoat layer laminated on a substrate are formed an optically readable region in which a dot pattern optically readable by an input terminal is printed and an optically unreadable region in which a dot pattern optically unreadable by an input terminal is printed, and the dot pattern formed in the optically unreadable region is a halftone tint having regularity whose halftone dot concentration is in the range of 10 to 30%. This pattern-printed sheet not only can be obtained by using a gravure printing method having outstanding production efficiency but also has a dot pattern readable with high reading precision in a prescribed dot size.

A garment having an outer surface not designed for writing has at least one rewritable area comprising a layer of rewritable material deposited directly onto a selected region of the outer surface. One or more permanent artworks may be deposited onto the garment prior to deposit of the rewritable layer, which may be contiguous or non-contiguous. A stencil is provided for allowing a user to write on rewritable areas while protecting adjacent areas of the garment. In one method for forming the rewritable area, a first portion of a permanent artwork and a second portion of the permanent artwork are successively deposited on the garment, followed by curing the permanent artwork and depositing a rewritable area on the garment.

An evidence ecosystem that includes a capture system that detects physical properties in the environment around the capture system and captures data related to the physical properties. The capture system analyzes the captured data in accordance with patterns to detect characteristics and patterns in the captured data. Upon detecting a characteristic or a pattern, the capture system records the identified data and alignment data that identifies the location of the identified data in the captured data. The capture system sends the captured data, identified data, and alignment data to an evidence management system for use in generating reports and producing redacted copies of the captured data for distribution or presentation.

A thermochromic display board is described that includes an array of nanofiber yarns in contact with an electrode. When electrified, the nanofiber yarns generate heat. This heat causes a thermochromic transition in a thermochromic layer. The presence of the nanofiber yarns, which are thermally conductive, can increase the rate at which the thermochromic layer within the di splay board transitions between thermochromic states.

Articles are described comprising a surface layer comprising at least one long hydrocarbon chain silane compound (C8-C36) bonded to a siliceous layer such as diamond-like glass. In an embodiment, the siliceous layer has a porosity of no greater than 10% and a thickness no greater than 1 micron. In another embodiment, the siliceous layer comprises 10-50 atomic percent carbon and the article further comprises an organic polymeric base member or a hardcoat layer. Also described are coating compositions comprising at least one C8-C17 hydrocarbon silane compound and at least one C18-C36 hydrosilane compound.

An erasable writable material for large format applications is disclosed, and includes a cast polyvinylchloride film with a mount surface opposite an etched receiver surface. Also incorporated is a transparent polyester film that has a marking side with a hardness exceeding approximately shore D 79 and an opposite seal side, hermetically laminated to the receiver surface. The marking side includes a clear superstrate that has a hardness exceeding approximately shore D 90, which is applied to the marking side of the polyester film to lower surface energy below about 24 millinewtons per meter. The receiver surface is treated to have a surface energy exceeding about 45 millinewtons per meter, to enable improved adherence of printed and preformed graphic elements, which are encapsulated when laminated between the PET film and receiver surface. The superstrate includes a perfluoropolyether, a polyurethane, an acrylated polyurethane, and/or an acrylate resin to harden the material.

Dry erase articles are described comprising a writable surface layer comprising a cured hardcoat composition comprising the reaction product of certain low surface energy compound(s). In one embodiment, the compound(s) comprise a C18-C36 hydrocarbon group and an ethylenically unsaturated group. In another embodiment, a mixture of compounds is utilized, the mixture comprising first compounds comprising a C18-C36 hydrocarbon group and an ethylenically unsaturated group and second compounds comprising a C8-C17 hydrocarbon group and an ethylenically unsaturated group, wherein the first and second compound are present at a weight ratio of 3:2 to 4:1.

A marker board system having a dark colored, low hardness, low surface energy solid silicone sheet to wet to a vertically oriented high surface energy substrate on a smooth, flat back-side of the solid silicone sheet. A front-side of the solid silicone sheet is able to be written upon by brightly colored marker ink. The brightly colored marker ink is able to be easily erased from the front-side of the solid silicone sheet after being written upon the front-side of the solid silicone sheet. The front-side is roughened to diminish beading of the brightly colored marker ink when written on the front-side.
