An aqueous polyurethane dispersion compositions are disclosed. The compositions include a polyurethane prepolymer dispersed in an aqueous medium, the polyurethane prepolymer comprising an isocyanate and a crystalline polyester polyol having a hydroxyl content of 20 to 150 mg KOH/g and a melt temperature of less than or equal to 90° C. Methods of forming a laminate are also disclosed. The methods include providing an aqueous polyurethane dispersion, applying the polyurethane dispersion to a surface of the first substrate, bringing the side of the first substrate into contract with a surface of the second substrate, and curing the aqueous dispersion, thereby laminating the first substrate to the second substrate. Laminates formed by the methods and including the compositions are also disclosed.

A plastic substrate includes: a plastic support member having light transmittance; and a first organic-inorganic hybrid layer on the plastic support member. The first organic-inorganic hybrid layer includes: a first organic-inorganic hybrid matrix; and ions implanted into the first organic-inorganic hybrid matrix at a side opposite to a side adjacent the plastic support member. An amount of the ions per unit area is in a range from about 2×10.sup.13/cm.sup.2 to about 2×10.sup.14/cm.sup.2.

Golf balls having covers made of thermoplastic polyurethane compositions are provided. Multi-piece golf balls can be made. Polyurethane primer coatings and polyurethane top-coatings are applied to the thermoplastic polyurethane cover. Different coating methods can be used. Isocyanate-rich and polyol-rich polyurethane coatings can be applied. In one embodiment, the golf ball can be treated with a multi-functional isocyanate prior to applying the coatings. The polyurethane cover composition and surface coatings can further include catalysts, ultraviolet (UV)-light stabilizers, and other additives. Heat is used to cure the coatings. The coating methods have many benefits and the finished balls have good physical properties.

This technology relates materials that are stab, spike and ballistic resistant and to stab, spike and ballistic resistant composite articles incorporating uniaxially oriented, non-woven fabrics. A fabric layer having a non-uniform areal density is formed having thick areas and thin areas, the thick areas having a greater filament/tape concentration compared to the thin areas. In said thick areas, agglomerated tapes/filaments will protrude from the fabric layer surface. Additional layers are then adjoined with the non-uniform layer to form a panel that has stab, spike and ballistic resistance, with protrusions at least partially spacing the additional layers from full, direct contact with the surface of the non-uniform fabric layer to thereby enhance flexibility and stab, spike and ballistic resistance of the whole.

A foldable display device according to the present disclosure includes a display panel including a display area and a non-display area, a touch panel disposed on the display panel and including a bridge electrode, a plurality of insulating layers, a first touch electrode, and a second touch electrode. The device includes a plurality of crack stoppers disposed in the non-display area of the touch panel and configured by patterning the insulating layers and an adhesive layer. The adhesive layer fills a space between the plurality of crack stoppers from which the insulating layers are removed, and is disposed between the display panel and the touch panel. Accordingly, crack occurrence may be suppressed even if a folding/unfolding operation of the foldable display device is repeated. Thus, crack occurrence in the foldable display device may be improved and at the same time, folding characteristics may increase.

Optical film stacks are described. More particularly, optical film stacks including a half-wave retardation layer are described. Achromatic half-wave retardation layers, including achromatic half-wave layers formed from a quarter-wave and a three-quarters-wave retardation layer, are described. Film stacks including reflective polarizers tuned to reduce wavelength dispersion of the half-wave retardation layer are also described.

In order to solve problems of strength and volume of part, the invention provides an article reinforced by multi-dimensional fibers and a method for manufacturing the article. The article includes a core portion and a shell layer portion. The core portion is made of thermoplastic resin and the fibers in which a majority of and a minority of the fibers are respectively arranged in a major and a minor directions. The method includes: preparing a core portion made of thermoplastic resin and the fibers in which a majority of and a minority of the fibers are respectively arranged in a major and a minor directions, loading the core portion into a mold, and forming a shell layer portion in the mold to enclose the core portion. The article manufactured by the method of this invention can reduce the weight and increase the strength of the parts.

Described herein are UV reflective particles, and methods of forming UV reflective particles, comprising extruding a film having a plurality of alternating layers of polycarbonate (PC) and poly(methyl methacrylate) (PMMA), wherein each layer is less than 150 nm thick, and grinding the film into particles having a median particle size less than 200 microns.
