MOSCOW (MRC) -- Japan's Kuraray Co., Ltd. has developed LEGENDA, a micropatterned film that can be used in such devices as LED lamps, reported the company in its press release.
Since this product can be used to produce a myriad of colors and effects when used in conjunction with conventional point-source LEDs, it holds great potential for applications in fields ranging from sophisticated designer lamps to toys and entertainment devices, which often demand particularly eye-catching visual properties.
To create the film, Kuraray first developed metal stampers using its own proprietary mastering technology. The company then developed a method of applying a UV-curable resin to the surface of a substrate film with the resultant film being simultaneously cured and stamped with intricate micropatterns to produce a unique light-shaping film.
By placing the film in front of an LED, a variety of effects can be achieved as the film refracts, reflects, scatters or diffracts the light, depending on the micropattern used.
Material that are suitable for such films production are acrylic film, PET, polycarbonate, etc.
As MRC wrote earlier, in December 2013, Kuraray and DuPont, the biggest US chemical maker by market value, signed a definitive agreement for DuPont to sell Glass Laminating Solutions/Vinyls (GLS/Vinyls), a part of DuPont Packaging & Industrial Polymers, to Kuraray for USD543 million, plus the value of the inventories. The sale is expected to close during the first half of 2014 pending customary regulatory approvals.
Kuraray has a long history in production of vinyl acetate production starting in 1926 with the production of synthetic rayon, which was cutting-edge technology at the time. In the 1950s, Kuraray became Japan's first domestic producer of synthetic fiber, becoming a world leader in the commercialization of PVOH (Kuraray Poval) fiber under the KURALON brand.
