A biodegradable cellulose fiber-based substrate, at least one side of which is coated with a release coating including: a) at least one water-soluble polymer (WSP) containing hydroxyl groups, and b) at least one lactone substituted with at least one linear or branched and/or cyclic C.sub.8-C.sub.30 hydrocarbon chain which may contain heteroatoms. The biodegradable substrate is certified biodegradable in accordance with EN 13432. A method of production thereof is also disclosed.

Photovoltaic cells which comprise a back plane comprising a polyester film and an adhesive coating derived from an ethylene vinyl acetate copolymer and an oxazoline crosslinking agent and methods for forming the same are described.

The invention features adhesive devices for holding objects (e.g., bone fragments) fixed with respect to each other.

The present invention provides a transparent electroconductive layer-equipped cover element having a pressure-sensitive adhesive sheet preliminarily laminated thereto, wherein the pressure-sensitive adhesive sheet comprises a pressure-sensitive adhesive layer in which a refractive index adjustment zone having a refractive index greater than that of a base pressure-sensitive adhesive material thereof is formed over a given range from a surface of the pressure-sensitive adhesive layer in a thickness direction thereof, whereby: in a lamination process of a customer which is a supply destination of the transparent electroconductive layer-equipped cover element, it becomes possible to eliminate a need to distinguish between obverse and reverse sides of the pressure-sensitive adhesive sheet itself; and, when the transparent electroconductive layer-equipped cover element is bonded to an optical element through the pressure-sensitive adhesive layer, it becomes possible to suppress internal reflection in a laminate formed of these optical elements.

An adhesive-coated polymer substrate comprising (a) a polymer substrate containing or consisting of a thermoplastic polymer with a Vicat A50 softening point according to DIN EN ISO 306 of up to 220° C., and (b) an adhesive composition coated directly on at least one side of the polymer substrate, wherein the adhesive composition (b) is a UV-curable or UV-cured hot melt pressure sensitive adhesive (PSA) is disclosed. A process for the manufacture of the adhesive-coated polymer substrate as well as to the use thereof are also disclosed.

A biodegradable pressure-sensitive adhesive which can be readily coated indirectly onto biodegradable carriers, which comprises

at least 60 wt % of at least one polyurethane, and
at least one sulfonated carboxylic ester; and a method for producing a biodegradable adhesive tape, which comprises providing a pressure-sensitive adhesive of the invention as a dispersion in at least one organic solvent; coating this dispersion onto a release liner; removing the organic solvent; and transferring the pressure-sensitive adhesive onto a biodegradable carrier.

A decorative decal for altering the aesthetics of a barbeque grill, with the decal comprising a flexible and heat resistant substrate having a visually discernible aesthetic element on its first surface and an adhesive on its second surface, with the adhesive suitable for attaching the substrate to the outer surface of the barbeque grill; and a method of use of the decal.

The present invention provides a biodegradable resin having an intrinsic viscosity of 1.0 dL/g or more, and having a loss rate of intrinsic viscosity of 10% or more after treatment at 70° C. and 85% RH for 6 hr. The present invention also provides a biodegradable resin containing 70 wt% or more of polylactic acid and having a relative biodegradation rate up to 90% or more within 12 months when the degradability in home composting at 28° C. is evaluated according to the conditions specified in ASTM D5338-15. The biodegradable resin has the characteristics of fast biodegradation speed and stable storage, has good mechanical properties, optical properties and barrier properties, can be applicable to various aspects including packaging and express transportation, and will quickly biodegrade into carbon dioxide, water and other small molecules without contamination to the environment at the end of service life. The present invention also provides a biodegradable resin film using the biodegradable resin and a product thereof, and a multilayer film containing the biodegradable resin film and a product thereof.

An adhesive tape includes a composite membrane and an adhesive layer, where the composite membrane includes a substrate and a hardening layer provided on a surface of the substrate, and a hardness of the hardening layer is 3H to 9H. The adhesive tape provided in this application has both small thickness and high hardness, which increases volumetric energy density of the electrochemical apparatus and can further effectively avoid tape wrinkling of the electrochemical apparatus.

The present disclosure relates to a multilayer protective film that may include a multilayer component and a release liner component underlying the multilayer component. The multilayer component may have a first PET layer overlying a second PET layer. The multilayer protective film may further have a thickness ratio MPF.sub.T:RL.sub.T of not greater than about 14:1, where MPF.sub.T is equal to the thickness of the multilayer component and RL.sub.T is equal to the thickness of the release liner component.
