Essilor patents photochromic
coating
U.S. 8,110,127 B2
Essilor International has been granted a
patent for a thermally curable pho-
tochromic coating composition com-
prised of a mixture having two different
monomers, where the monomers are se-
lected from the group consisting of
monofunctional (meth)acrylate; difunc-
tional (meth)acrylate; a combination of
a monofunctional (meth)acrylate and a
difunctional (meth)acrylate; multifunc-
tional (meth)acrylate; and aliphatic ure-
thane diacrylate; a metal salt selected
from the group consisting of a metal
ester of 2-naphthoic acid, a metal ester
of 2-ethylhexanoic acid, a metal ester of
octoate material, and combinations
thereof; a hindered amine light stabilizer
(HALS); an antioxidant; an initiator se-
lected from the group consisting of t-
amylperoxy-2-ethylhexyl carbonate
organic peroxide and t-butylperoxy-2-
ethylhexylcarbonate; and a pho-
tochromic dye.
LG Chem patents UV-curable
antireflective coating
U.S. 8,110,249 B2
LG Chem, Ltd. has obtained a patent for
an antireflective coating composition comprised of a photopolymerizable acrylate
monomer (C1); a particulate metal fluoride (C2) with a refractive index of 1.40 or
less; a photopolymerization initiator (C3);
and at least one liquid dispersion-enhanc-ing chelating agent (C4) selected from the
H.B. Fuller patents hot melt
pressure sensitive adhesive
that contains vegetable wax
U.S. 8,110,623 B2
H.B. Fuller Company has received a
patent for a hot melt pressure-sensitive
adhesive composition comprised of a
thermoplastic elastomer comprised of a
block copolymer comprised of at least
one A block comprised of polyvinyl aromatic compound and at least one B
block comprised of an elastomeric un-hydrogenated conjugated diene, hydrogenated conjugated diene or a
combination thereof; tackifying agent;
plasticizer oil; and from at least 5% by
weight to approximately 25% by weight
vegetable wax the pressure-sensitive adhesive composition exhibiting an onset
of crystallization from melt of no greater
than approximately 50° C.
Coated article supporting
photocatalytic layer and UV-reflecting underlayer
U.S. 8,110,297 B2
Guardian Industries Corp. has been
awarded a patent for a coated article
comprised of a substrate supporting a
coating. The coating is comprised of a
UV-reflecting coating disposed, directly
or indirectly, on the substrate, wherein
the UV-reflecting coating is comprised
of at least 0.1% by weight aluminum
oxide, and at least 0.1% by weight material having a refractive index higher
than the aluminum oxide, and wherein
the material having the refractive index
higher than the aluminum oxide includes at least one: zirconium oxide, yttrium oxide, hafnium oxide, and oxides
of rare earth metals; and a photocatalytic layer disposed over the UV-reflecting coating so that at least some of
any UV light that is not initially used in
the activation of the photocatalytic
layer and otherwise would pass into the
substrate is reflected back towards the
photocatalytic layer by the UV-reflecting coating. CW
