Compound
The present application relates to a curable composition, a cured product and uses of the curable composition and the cured product. By comprising the curable compound having a certain structure, the present application can provide a curable composition which can increase cohesiveness of the cured product without increasing viscosity of the composition before curing, also minimize the increase of the elastic modulus, and also minimize the ratio of a nonreactive oligomer with an effect of improving the interfacial adhesion. The curable composition can be applied to a variety of optical applications and can be usefully used, for example, for bonding various optical functional members in a display device, for example, for directly bonding a touch panel and a display panel.
LIQUID CRYSTAL ALIGNING AGENT CONTAINING CROSSLINKING AGENT AND POLYMER THAT HAS SITE HAVING ISOCYANATE GROUP AND/OR BLOCKED ISOCYANATE GROUP AND SITE HAVING PHOTOREACTIVITY, LIQUID CRYSTAL ALIGNMENT FILM, AND LIQUID CRYSTAL DISPLAY ELEMENT
Provided is a liquid crystal display element that can be baked at a low temperature when forming a liquid crystal alignment film capable of imparting an alignment regulating property and a pretilt angle developing property via a photoalignment method. Further provided is a liquid crystal display element in which the liquid crystal pretilt angles are highly stable, and display burn-in hardly occurs even due to long usage. Further provided are a vertical liquid crystal alignment film to be used in the liquid crystal display element, and a liquid crystal aligning agent with which it is possible to provide the vertical liquid crystal alignment film. A liquid crystal aligning agent of the present invention contains: component (A), which is a polymer including (A-1) a site having an isocyanate group and/or a blocked isocyanate group and (A-2) a site having photoreactivity; component (B), which is a compound having, in a molecule, at least two functional groups of at least one type selected from the group consisting of an amino group and a hydroxyl group; and an organic solvent.

ADJUSTABLE INSULATED RECEPTACLE FOR BEVERAGE CONTAINERS
An adjustable insulated receptacle comprising an upstanding wall that surrounds and defines a cavity of the receptacle which is sized and shaped to receive a beverage container. The receptacle further includes a base closing a lower end of the cavity, a rim surrounding an upper end of the cavity, and a vertical slot that is contiguous with the rim, has a lowermost extent adjacent the base, and has opposing edges between the rim and the lowermost extent. The slot is sized and shaped to receive a handle of the beverage container that protrudes from the cavity. The receptacle further includes a means for releasably securing the edges of the slot relative to each other to maintain a width of the slot and, in turn, an internal diameter of the cavity. The securing means comprises a strap that bridges the slot.
