摘要： This invention provides a magnetic fluid having a rich hue and containing an organic compound as dispersion medium.
The magnetic fluid of this invention is constructed by mixing, into a magnetic dispersion, a colorant prepared by beforehand treating a coloring material with a solubilizing treating agent or a dispersibilizing treating agent. Said solubilizing treating agent or dispersibilizing treating agent has a hydrophobic group and a functional group adsorbable or linkable to said coloring material. As said coloring material, a dyestuff, an organic pigment or an inorganic pigment is used. A colorant prepared by subjecting an intermediate of said coloring material to said treatment is also usable. Further, a colorant prepared by pretreating a coloring material so as to give the coloring material an adsorbability or a linkability to said solubilizing treating agent or dispersibilizing treating agent and then subjecting the beforehand pretreated coloring material to said treatment is also usable.
The magnetic fluid of this invention can retain its initial hue stably for a long period of time, and its hue can be changed without substantially changing the properties of magnetic fluid such as magnetization, viscosity and the like. Accordingly, the magnetic fluid of this invention can be applied extensively to all the use fields of magnetic dispersions, and it exhibits a particularly great effect when applied to uses of developer or ink in the field of printing and recording.

摘要： This invention is directed to a polymeric thermo-sensitive material which comprises a polyamide composition containing compounds of sulphur-contained compounds or phosphorous acid ester, and which is smaller in polarization in the application of direct-current electric field, higher in temperature detection function, does not cause flexibility deterioration due to heating operation and is less in hygroscopicity. A composition containing thiophosphorous acid ester and bis(hydroxyphenyl) sulfide derivative from a group of the phosphorous acid ester is particularly superior in quality.

摘要： This invention provides magnetic fluids having various hues. The magnetic fluids of this invention are constituted of a dispersion of colloidal coloring pigment particles and a dispersion of ferromagnetic particles. Said coloring pigment particles consist of an inorganic pigment such as cobalt blue, carbon black orthe like or an organic pigment such as copper phthalocyanine, pigment scarlet or the like, and are dispersed as colloidal particles. By the selection of the coloring pigment particle, a magnetic fluid having a black hue or an arbitrary hue can be obtained. The magnetic fluids of this invention exhibit their excellent characteristic properties particularly when used as a recording material. For example, when the magnetic fluid of this invention is used as an ink for making a record on high quality paper, no color separation takes place on the paper surface between the magnetic particles and the coloring pigment particles, and the recorded image keeps its hue stably for a long period of time without color change.

摘要： An image forming process comprising steps of arranging on a support member, in accordance with image signals, image forming particles containing dye former which develops its color in reaction with a color developing agent, heat-transferring the dye former from the particles to an image receiving substrate. After the heat-transfer step, the color developing agent is caused to adhere to the dye former heat-transferred on the image receiving substrate to provide colored images.
Choice of the image receiving substrate and the color developing agent is expanded. Fogging is not caused, color purity is not lowered, and the other image receiving material is not polluted due to re-evaporation of the dye former which is on the image receiving substrate and is not reacted with color developing agent.
