  • Patent number: 10910010
    Abstract: A reversible recording medium according to an embodiment of the present disclosure is a reversible recording medium that includes recording layers and heat-insulating layers that are alternately stacked, in which the recording layers each include a reversible heat-sensitive color developing composition and a first light-heat converting agent. In this reversible recording medium, the recording layers are different from each other in a developing color of their respective reversible heat-sensitive color developing compositions and are different from each other in an absorption wavelength of their respective first light-heat converting agents. This reversible recording medium further includes a heat-generating layer that includes a second light-heat converting agent having an absorption wavelength that is different from the absorption wavelength of the first light-heat converting agent included in each of the recording layers.

  • Patent number: 10808152
    Abstract: The present invention aims to provide an adhesive composition which enables achievement of highly strong adhesion between a lightweight composite resin and a lightweight metal member, and which can maintain excellent adhesive strength even in cases where the ambient temperature largely changes or the adhesive composition is in contact with water or a snow-melting agent, and an adhesive sheet using it. The above object can be achieved with an adhesive composition containing at least an epoxy resin, an acrylic particle, and a curing agent, wherein the acrylic particle is a core-shell structure containing a butadiene-based rubber, and polymethacrylate or polyacrylate. The adhesive sheet is constituted such that an adhesive layer formed with the adhesive composition is present between a first release film and a second release film.
