摘要:
An edible microcapsule comprising a core and a capsule wall, wherein the core is an edible hydrophobic substance, the capsule wall is formed by salting-out of a combination of a protein and an edible salt, and transglutaminase is used as a crosslinking agent for hardening (solidifying) the capsule wall, and a food containing the edible microcapsule.

A microencapsulated photochromic material, a process for its preparation, and a water-base ink composition prepared therefrom are disclosed. The microencapsulated photochromic material comprises a solution of a spirooxazine compound enclosed in microcapsules. The process for preparing the microencapsulated photochromic material comprises dissolving the spirooxazine compound in a solvent having a boiling point of 40 to 160°C and a solubility in water (at 20°C) of up to 15 wt %, microencapsulating the solution, and evaporating most of the solvent during or after the microencapsulating step, thus leaving only a minute amount of the solvent. The water-base ink composition comprises an aqueous medium, a colorant and a vehicle as major components, said colorant being the microcapsules containing the solution of a photochromic compound, said vehicle being an aqueous emulsion resin, and said composition having a pH of 5 or more.
摘要:
Ein Bildschirmsystem auf magnetischer Basis, bei dem auf die Rückseite eines transparenten Bildschirmträgers (2) ein Belag (7) aufgetragen ist, in dem Kapseln (5A,5B) eingelagert sind, in denen magnetische, lichtabsorbierende und unmagnetische, lichtreflektierende Partikel (3,4) dispergiert sind. Um die Qualität des erzeugten Bildes zu verbessern, insbesondere was den hell/dunkel-Kontrast und die Konturenschärfe betrifft, enthält der Beleg (7) zusätzliche, lediglich Öl enthaltende Kapseln (6) wesentlich kleineren Durchmessers als die der Kapseln (5A,5B). Die Kapseln (5A) enthalten auch permanentmagnetische Partikel (9). Das Bild wird durch die Verlagerung aktivierter, magnetischer lichtabsorbierender Partikel (3) zur Frontseite des Bildschirms (1) und gleichzeitige gegenläufige Verlagerung der unmagnetischen Partikel (4) erzeugt.
摘要:
A magnetic display system is disclosed, which comprises a display including a non-magnetic substrate and a microcapsule coating layer provided on the substrate and having sealed magnetic particles having an excellently light-absorptive surface character and also sealed non-magnetic particles having an excellent light-reflective character, both the magnetic and non-magnetic particles being dispersed or dissolved in an oily liquid, and magnetic means for reversing the position of the light-absorptive magnetic particles and light-reflective non-magnetic particles in the microcapsules. The magnetic means causes local shift by attraction of the light-absorptive magnetic particles in the microcapsules coating layer of the display to the front side thereof to thereby invert the position of the light-reflective non-magnetic particles in the corresponding areas, thereby forming characters or images.

摘要:
A magnetic display capable of colorizing an image formed on the display surface and of solving the problem of the angle dependency of an interference color to thereby eliminate color change occurring due to different viewing angles is provided. In the magnetic display, black color that is a color inherently exhibited by magnetic particles to be provided as indispensable character, and image-forming elements is converted into a wide variety of colors without using any coloring material or the like. The magnetic display has two non-magnetic substrates, at least one of which is transparent; and a microcapsule coating layer is applied between the non-magnetic substrates. The microcapsules contain and seal light-absorptive black magnetic fine particles and light-reflective non-magnetic fine particles being dispersed in an oily dispersion liquid. An array layer is buried in a capsule wall of each of the microcapsules enclosing the oily dispersion liquid that contains the light-absorptive black magnetic fine particles and light-reflective non-magnetic fine particles, in which flake shape particles consist of a multi-layered structure for converting the black color of a character or image formed on a display surface, which is a color inherently exhibited by the light-absorptive black magnetic fine particles, into a variety of interference colors are arranged so as to be oriented parallel to the surface of the capsule wall along the entire spherical surface of the microcapsule.
摘要:
To provide a magnetic display in which a character or image of a black color formed of magnetic fine particles such as black iron oxide fine particles may readily be changed into a variety of interference colors with a simple structure without deteriorating a function of a conventional magnetic display. A microcapsule layer containing and sealing light-reflective non-magnetic fine particles and black magnetic fine particles dispersed in an oily liquid is coated in a space between two non-magnetic substrates at least one of which is transparent to form a display sheet, a magnetic field for forming a character or image is applied from a surface of the display with a transparent substrate side being a front surface side thereof and a magnetic field for erasing the character or image is applied from a back surface thereof so that positions of the black magnetic fine particles and the light-reflective non-magnetic fine particles within the microcapsules are inverted to thereby form the character or image. A pearl pigment layer exhibiting a variety of interference colors is applied onto the front surface or the back surface of the transparent substrate.
