  • Publication number: 20220146719
    Abstract: A reflective display body configured such that the up-down direction of display content on a display surface can be changed. The reflective display body includes a light diffusion control layer, a display device, and a reflective layer. The light diffusion control layer has a diffusion angle width of 5° or more and 80° or less in which a haze value (%) is 90% or more as measured when one surface of the light diffusion control layer is irradiated with light rays at an incident angle of ?70° to 70° with respect to the normal direction of the one surface being 0°. The light diffusion control layer has an acute angle of 7° or more and 83° or less.

  • Publication number: 20210005919
    Abstract: A battery (2) comprising a pressure sensitive adhesive sheet (1) and an electrolyte solution, wherein: the pressure sensitive adhesive sheet is provided at a site in the battery in which there is a possibility of contact with the electrolyte solution; the pressure sensitive adhesive sheet comprises a base material (11) and a pressure sensitive adhesive layer (13) laminated at one side of the base material; and the pressure sensitive adhesive layer (13) is formed of a pressure sensitive adhesive composition comprising: a (meth)acrylic ester polymer having a main chain containing (meth)acrylic alkyl ester monomer units having a carbon number of an alkyl group of 6 or more and 20 or less, and carboxy group-containing monomer units, wherein the (meth)acrylic alkyl ester monomer units having a carbon number of an alkyl group of 6 or more and 20 or less contain 2-ethylhexyl (meth)acrylates and (meth)acrylic alkyl ester monomer units having a carbon number of an alkyl group of 10 or more and 20 or less.

  • Patent number: 10826106
    Abstract: [Problems] An object is to provide a pressure sensitive adhesive composition, a pressure sensitive adhesive sheet for batteries, and a lithium-ion battery in which the pressure sensitive adhesive is less likely to dissolve into an electrolyte solution even when the pressure sensitive adhesive sheet is in contact with the electrolyte solution. [Solution] A battery (2) comprising a pressure sensitive adhesive sheet (1), wherein: the pressure sensitive adhesive sheet is used at a site in the battery at which there is a possibility of contact with an electrolyte solution; the pressure sensitive adhesive sheet comprises a base material (11) and a pressure sensitive adhesive layer (13) laminated at one side of the base material; and the pressure sensitive adhesive layer is formed of a pressure sensitive adhesive composition comprising: a (meth)acrylic ester polymer containing a monomer having a carboxy group in a molecule as a monomer unit that constitutes the polymer; and a metal chelate-based crosslinker.

  • Patent number: 10550290
    Abstract: [Problems] Objects include providing a pressure sensitive adhesive sheet for batteries that is excellent in the insulation properties even after heated to high temperatures and also excellent in the insulation properties even when immersed in an electrolyte solution for a long time and then heated to high temperatures and also providing a lithium-ion battery in which the pressure sensitive adhesive sheet for batteries is used. [Solution] A pressure sensitive adhesive sheet for batteries (1), comprising: a base material (11); a hard coat layer (12) provided at one side of the base material (11); and a pressure sensitive adhesive layer (13) provided at a side of the hard coat layer (13) opposite to the base material (11), the hard coat layer (12) being formed of a composition for hard coat layer that contains a metal oxide sol, the metal oxide sol being a sol of a metal oxide that has insulation properties.
