摘要： PROBLEM TO BE SOLVED: To provide a magnetic display which is capable of easily converting the black characters and images formed by magnetic particles of fine black iron oxide powder, etc., to diversified interference colors with simple constitution without impairing the functions of the conventional magnetic displays. SOLUTION: This magnetic display is constituted by coating and providing two sheets of nonmagnetic material substrates 8 and 9, at least one of which is transparent, with a microcapsule layer 7A of the fine black magnetic powder dispersed into oily liquid and fine light reflective nonmagnetic material powder between these substrates to form the display sheet, and forms and images by impressing the magnetic field for forming the characters or images from the front surface of the display having the transport 8 side as the front surface and impressing the magnetic field for image erasure from the rear surface, thereby converting the positions of the fine black magnetic material powder and fine light reflective magnetic material powder within the microcapsule 7. The front surface or rear surface of the transport 8 is coated and provided with a pearl pigment layer 16 indicating various kinds of the interference colors.

摘要： PROBLEM TO BE SOLVED: To provide a temperature-sensitive and discoloring laminate which is highly color-variable and concealable with the capability of upgrading the light resistance. SOLUTION: This temperature-sensitive and discoloring laminate is composed of a reversible thermally discoloring layer 3 having a coloring material which contains a coloring agent, a developer and a desensitizing agent and reversibly discolors from a color to a colorless transparency at a set temperature or above. An ink layer 4 containing a pearl pigment is laminated on the former 3.

摘要： PROBLEM TO BE SOLVED: To provide a magnetic display which enables the colorization of an image formed on a display surface and in which a color change by an angle to see is eliminated by eliminating the angle dependency of an interference color by converting a black color specific to a magnetic particle, an indispensable element as a formative element for a character or an image, into other various colors without using coloring materials, etc. SOLUTION: The magnetic display is formed by coating a microcapsule layer 7A enclosing the fine powders 5 of a light absorbing black magnetic material and the fine powders 6 of a light reflective nonmagnetic material which are dispersed in an oily dispersion liquid 4 between two nonmagnetic material substrates 2 and 3 one of which is transparent. An array layer 9A is arranged and embedded in the wall film 8 of a microcapsule 7 which encloses the oily dispersion liquid 4 of the fine powders 5 and the fine powders 6 so that planar particles 9 which form a multiplex layer structure to convert the black color specific to the fine powders 5 to be shown as the character or the image on the display surface 1 into the interference color are aligned in parallel with the wall film 8 throughout the spherical surface of the microcapsule 7.

摘要： PROBLEM TO BE SOLVED: To make a film of a microcapsule produced by coacervation method airtight. SOLUTION: The microcapsule film of which is made airtight can be obtained by coating the microcapsule produced by the coacervation method with a saccharide and/or a saccharide alcohol. As the saccharide or the saccharide alcohol, glucose, sucrose, maltose, trehalose, sorbitol, multitol or the like can be cited. In the microcapsule of this invention, volatilization of a core substance being an oily liquid or deterioration and discoloring by air oxidation can be prevented. In particular, when oily perfume is used as the core substance, perfume components are excellently held and when medicine components or the like susceptible to oxidation are used, preservation stability thereof is excellent.

摘要： PROBLEM TO BE SOLVED: To provide a method for producing microcapsules containing a flavor oil, by which the flavor oil containing a complicated ingredient system that is difficult to microcapsulate by a conventional coacervation method, such as a flavor oil containing an unpurified animal or vegetable oil or fat, a natural oleoresin, a polar compound and a surfactant, can simply be microcapsulated in a state holding the original flavor. SOLUTION: This method for producing microcapsules containing an aroma oil comprises stirring a mixture comprising an aroma oil, an aqueous liquid, and lecithin or an emulsifier having an HLB value of 0.1 to 4 to form a W/O type emulsion, adding the formed W/O type emulsion to an aqueous gelatin solution at a higher temperature than the gelling point of the gelatin, stirring the mixture, adding the aqueous solution of a coacervating agent to the mixture to form the coacervates of the gelatin around the W/O type emulsion particles, and then holding the W/O type emulsion at a lower temperature than the gelling point of the gelatin to harden the coacervates.
