The invention relates to a thermoplastic molding composition comprising 5.0 to 57 wt.-% ABS graft copolymer (A); 30.5 to 80 wt.-% SAN copolymer (B) 1.5 to 9.5 wt.-% copolymer (C) with epoxy, maleic anhydride or maleic imide functions; 5 to 29 wt.-% of hollow glass microspheres (D); 6 to 12 wt.-% of glass fibers (E); 0 to 5 wt.-% additives and/or processing aids (F), having a low density and high strength, and a process for its preparation, shaped arti-cles thereof, and its use in the electronics sector.

A multilevel antimicrobial polymeric colloidal particle includes a polymer scaffold and at least one antimicrobial polymer carried on the polymer scaffold, where the polymer scaffold and the at least one antimicrobial polymer form a hollow colloidal particle. An antimicrobial core may be received within the hollow colloidal particle. The multilevel antimicrobial polymeric colloidal particles may be incorporated into an optically clear acrylic material to form an antimicrobial coating. The antimicrobial coating may be coated and ultraviolet cured onto a glass, metal or plastic substrate or the like to form a screen for electronic devices or the like which has antimicrobial properties.

Disclosed is a photochromic composition comprising a naphthopyran-based photochromic compound having a specific structure and an oligomer.

The present subject matter relates to self-healing keyboards. In an example implementation, a self-healing keyboard of an electronic device comprises a self-healing film having a self-healing layer disposed over a keyboard. The self-healing layer is composed of polyurethane, epoxy vinyl ester, epoxy, polyurethane microcapsules filled with silane compound, and a polysiloxane mixture.

Provided is a thermoplastic composite, a method for preparing a thermoplastic composite, and an injection-molded product. The thermoplastic composite comprises 35-75% by weight of a thermoplastic resin, 5-45% by weight of a non-cellulosic organic fiber, and 5-20%) by weight of hollow glass microspheres, based on 100% by weight of the total weight of the thermoplastic composite.

The disclosure relates to porous and non-porous silica capsules (capsules in capsule or core-shell capsules), porous microspheres, as well as their direct phase emulsification process without surfactant and their use, wherein the particles comprise a liposoluble active/payload.

The present invention provides a microcapsule encompassing water or a water-soluble compound and having excellent leakage resistance and morphological stability. Further, the present invention provides a method for producing the microcapsule.

The microcapsule of the present invention is a microcapsule encompassing at least one of water or a water-soluble compound, in which a capsule wall of the microcapsule contains a resin having a repeating unit derived from a hydrophobic monomer having a ClogP value of 0.70 or more and a repeating unit derived from a hydrophilic monomer having a ClogP value of less than 0.70, and the microcapsule satisfies a relationship of Expression (1).

[00001]$\begin{array}{cc}\delta /\mathrm{Dm}\le 0.40& \mathrm{Expression}\left(1\right)\end{array}$

δ represents a number average wall thickness (μm) of the microcapsule. Dm represents a volume-based median diameter (μm) of the microcapsule.

Hollow particles having a shell including at least one layer, wherein the at least one layer contains a vinyl-based resin, and contains a phosphorus atom and/or a sulfur atom.

A rubber composition for a tire tread contains a diene rubber, silica, and a cured product; a content of the silica being from 20 to 100 parts by mass per 100 parts by mass of the diene rubber, a content of the cured product being from 0.3 to 30 parts by mass per 100 parts by mass of the diene rubber; the diene rubber containing a natural rubber and a modified butadiene rubber having a polyorganosiloxane group at a terminal, a content of the natural rubber in the diene rubber being from 30 to 90 mass %, a content of the modified butadiene rubber in the diene rubber being from 10 to 70 mass %; the cured product being a cured product obtained by curing a crosslinkable oligomer or polymer that is incompatible with the diene rubber; and a JIS A hardness of the cured product being from 3 to 45.

Perfume microcapsule-containing films, related solutions, and containers including the films (e.g. detergent packets) are disclosed, together with their methods of preparation and use.
