Various non-limiting embodiments of the present disclosure relate to ophthalmic devices comprising photochromic materials comprising a reactive substituent. For example, the present disclosure contemplates ophthalmic devices comprising photochromic materials, such as photochromic naphthopyrans and indeno-fused naphthopyrans having a reactive substituent comprising a reactive moiety linked to the photochromic naphthopyran by one or more linking groups. In certain non-limiting embodiments, the reactive moiety comprises a polymerizable moiety. In other non-limiting embodiments, the reactive moiety comprises a nucleophilic moiety. Other non-limiting embodiments of the present disclosure relate to methods of making the photochromic ophthalmic device, wherein the photochromic ophthalmic devices comprise the photochromic naphthopyrans described herein.

A surface-treated polymer film is disclosed. The film has a polymer substrate having a first surface and an opposing second surface and a primer applied to the first surface of the substrate. The primer is a cross-linked acrylic polymer or other suitable polymer. A method of insulating a surface with an insulation material constructed from the surface-treated polymer is also disclosed.

An acoustical vinyl tile having an integral acoustical layer is disclosed. The vinyl tile includes a vinyl portion and an acoustical portion. The acoustical portion may comprise a crumb rubber component and a polyurethane foam component. The acoustical portion can include 10-40% crumb rubber and 60-90% polyurethane foam. The acoustical portion may comprise a plurality of individual layers, the combination of which is customized to the particular sub-floor structure to which the tile will be adhered or overlain. The individual layers of the acoustical portion can include any of a variety of combinations of rubber, cork, polyurethane foam, and the like. The resulting tile meets one or more of ASTM E 2179, ASTM E 989, ASTM E 492, and ASTM E1007 IIC sound requirements. A method of designing the disclosed tile to suit a particular flooring application is also disclosed. Other embodiments are described and claimed.

Benzoylthiourea or benzoylthiourethane derivatives as cure accelerators for two part curable compositions are provided.

Films useful as optical reflectors are prepared by coating a sheet of polyethylene terephthalate or other thermoplastic with acrylic polymer, white pigment, and optionally other additives such as impact modifiers, matting agents and UV stabilizers.

Provided is an acrylic resin laminate film which has an excellent bonding property, resistance to water blushing, and an excellent external appearance. This acrylic resin laminate film is provided with: an acrylic resin layer (I) comprising an acrylic resin composition (A); and an acrylic resin layer (II) comprising a resin composition (B) that contains a reactive group-containing acrylic resin (B-1). (B) contains 10-100 mass % of (B-1), and 0-90 mass % of (B-2), which is an acrylic resin other than (B-1), with respect to 100 mass % of the total of (B-1), and (B-2), and further contains 0-50 parts by mass of (C), which is an additive other than (B-1), and (B-2), with respect to 100 parts by mass of the total of (B-1), and (B-2). (B-1) contains a monomer unit which has a substituent that reacts with an amino group, or a methylol group. The content of the monomer unit that has the reactive substituent is 3 mass % or more with respect to 100 mass % of (B).

A multilayer encapsulation thin-film and a method and apparatus for preparing a multilayer encapsulation thin-film are provided. The multilayer encapsulation thin-film includes an inorganic thin film that includes a metal oxide, and an organic thin film that includes a polymer and is formed on the inorganic thin film, where the inorganic thin film and the organic thin film are alternately stacked in multiple layers

A method for depositing a coating comprising a polymer and pharmaceutical agent on a substrate, comprising the following steps: discharging at least one pharmaceutical agent in a therapeutically desirable morphology in dry powder form through a first orifice; discharging at least one polymer in dry powder form through a second orifice; depositing the polymer and/or pharmaceutical particles onto said substrate, wherein an electrical potential is maintained between the substrate and the pharmaceutical and/or polymer particles, thereby forming said coating; and sintering said coating under conditions that do not substantially modify the morphology of said pharmaceutical agent.
