摘要:
There is provided an emulsion coloring material which can be used on ordinary paper, has good color developability, and can be used for conventional erasable pens or printing inks of black or blue color, having sufficiently high densities. When use is made of an erasable emulsion coloring material capable of controlling color development and decolorization by the presence or absence of the interaction between a chromatic material and a color developer, the colored emulsion comprising a copolymer resin of at least one unit selected from styrene and styrene derivatives and at least one unit selected from an acrylic acid ester and a methacrylic acid ester having a substituent which comprises a carbon chain having 4 or more carbon atoms, coloring ability can be enhanced.

According to one embodiment, an image erasing apparatus decolors an image printed on a paper sheet using an ink containing at least a leuco dye, a developer, water, a water-soluble organic solvent, and a surfactant. The image erasing apparatus includes a heating unit, a feedback mechanism, and a control unit. The heating unit heats the paper sheet. The feedback mechanism supplies the paper sheet heated by the heating unit to the heating unit again. The control unit causes the feedback mechanism to supply the paper sheet to the heating unit a plurality of times so as to heat the paper sheet a plurality of times.

According to one embodiment, a method for separating a solvent from an object solution includes the solvent and a solute is provided. The method includes preparing a forward osmosis membrane having a first surface and a second surface, and contacting the first surface of the membrane with the object solution and contacting the second surface with a liquid for collection. A substance having solidity is configured to exert a force for transferring the solvent in the object solution to the membrane, and disposed on the second surface of the membrane and/or dispersed in the liquid for collection to transfer the solvent in the object solution from the first surface to the liquid for collection.

The present invention provides an impact absorption sheet for flat panel display with a polyoxyalkylene-series polymer as the main component, preferably, an impact absorption sheet for flat panel display made of a cured product obtained by curing a composition containing (A) polyoxyalkylene-series polymer having at least one alkenyl group in each molecule, (B) compound having an average of 2 or more hydrosilyl groups in each molecule, and (C) hydrosilylation catalyst.According to the present invention, an impact absorption sheet for flat panel display can be obtained, which can meet the size reduction and weight reduction of flat panel display, and which affords practically sufficient impact absorbability even in an area of thin film where practically sufficient impact absorbability has not been conventionally achieved. According to the present invention, moreover, an impact absorption sheet for flat panel display can be obtained, which not only has superior impact absorbability but is also superior in easy adhesion to flat panel display and redetachability after adhesion.
