Spherical polyester-based resin particles characterized in that the spherical polyester-based resin particles contain a polyester-based resin and have a crystallinity of 20% or less and an average circularity of 0.96 or more. The spherical polyester-based resin particles according to the present invention can provide suitable resin particles as compounding agents for cosmetics such as foundation, antiperspirants, and skin scrubs; various agents such as matte coating agents for paints, rheology modifying agents, antiblocking agents, slipperiness-imparting agents, light diffusion agents, electroconductive agents, and diagnostic testing agents for medical use; and additives to molded articles such as automobile materials and construction materials.

The present invention provides a window film, a manufacturing method thereof, and a display device including the same. The window film comprises: a basic material layer; a window coating layer formed on one surface of the basic material layer; and a back coating layer formed on the other surface of the basic material layer, wherein the window film has a relation of formula 1.

A membrane covered panel and a membrane covered panel production method are provided wherein an elastomeric membrane, and preferably, an aqueous elastomeric resin-based membrane, is applied to a finished panel construct, prior to pressing of the membrane covered panel. The method is used to produce panels which can be used in the production of flooring materials, wall panels, furniture, countertops, and the like. The membrane is applied to a transfer film, which transfer film can be removed at any time prior to, or after the pressing operation. The panels produced have a durable but elastic surface which can protect the surfaces of the panel construct. The elastomeric covering on the panel construct also preferably provides a surface which is abrasion resistant, and provides better acoustical properties while providing a soft touch haptic surface.

The invention relates to a composition intended for coating polymer films, making it possible to improve the adhesion between the film and a final coating, and to confer good barrier properties on the coated film. The coating composition comprises at least one acrylic and/or methacrylic polymer which has a gel content of at least 50% by weight, relative to the total weight of acrylic and/or methacryclic polymer, at least one crosslinking agent and at least one polyester comprising sulphonyloxy groups, which is water-soluble or water-dispersible.

The invention relates to a single- or multilayer polyester film with transparency at least 93%, where the film includes a UV stabilizer in all film layers and has a permanent antifog coating on at least one side. The permanent antifog coating is the dried product of an aqueous coating dispersion having the following components: a) from 1 to 15% by weight (based on the coating dispersion) of a soil release polymer and b) from 3 to 15% by weight (based on the coating dispersion) of a hygroscopic, porous material. The invention further relates to a process for the production of the film and to its use.

The present invention pertains to a resin composition which includes component: a membrane-forming polymer, component: a polymer obtained by polymerizing a monomer composition which includes a (meth)acrylic ester macromonomer represented by general formula and another monomer, and component: a polymer including a vinylpyrrolidone unit, a membrane-forming stock solution which includes the resin composition, a porous membrane obtained by forming with the membrane-forming stock solution, and a hollow fiber membrane, a water treatment device, an electrolyte support, and a separator which use the porous membrane.
