摘要:
A reversible thermosensitive recording material is composed of a support and a reversible thermosensitive recording layer formed thereon, which is capable of recording and erasing images repeatedly by utilizing its property that the transparency can be changed reversibly from a transparent state to an opaque state, and vice versa, depending upon the temperature thereof. The reversible thermosensitive recording layer is composed of a reversible thermosensitive layer and a protective layer formed thereon and has a scratching intensity of 10 g or more and a coefficient of friction of 0.10 or less. Images are reversibly formed and erased on this reversible thermosensitive recording material.
摘要:
A method of producing a reversible thermosensitive recording material composed of a support, and a reversible thermosensitive recording layer formed thereon, which contains a matrix resin and an organic low-molecular weight material dispersed in the matrix resin, and capable of reversibly assuming a transparent state and a white opaque state depending upon the temperature thereof, is composed of the steps of applying a solution or dispersion of the matrix resin and the organic low-molecular-weight material dissolved or dispersed in a solvent to the support, and drying the applied solution or dispersion with the application of heat thereto in such a manner that when the temperature of the solution or dispersion applied side of the support it t.sub.1, and the temperature of the back side surface of the support, opposite to the solution or dispersion applied side thereof, is t.sub.2, t.sub.1 is lower than t.sub.2 (t.sub.1
摘要:
A reversible thermosensitive recording material is composed of a support and a reversible thermosensitive recording layer formed on the support. The reversible thermosensitive recording layer includes a matrix resin and an organic low-molecular-weight material dispersed in the matrix resin, and has a temperature-dependent transparency. The matrix resin includes a resin component having a glass transition temperature of 90.degree. C. or more.
摘要:
A method of compensating for the distortion in a recording layer of a reversible thermosensitive recording medium, for which transparency of the recording layer is changeable, depending upon the temperature thereof, and the recording layer is capable of forming images and erasing the images reversibly. The distortion in the recording layer is caused by the repeated image formation by image formation means and/or image erasure by image erasing means. In this method, stress is applied to the recording layer before and/or after image formation by the movement of the recording medium relative to the image formation means, in a direction different from the direction of the application of stress in the course of a previous image formation or image erasure. Instead of the stress, thermal energy can be employed for compensating for the distortion in the recording layer.
摘要:
An image recording method of recording information in and erasing recorded information from a display medium which contains a reversible thermosensitive recording material capable of writing information therein and erasing recorded information therefrom by the application of heat thereto, by use of a heat application member with a flat portion by bringing the flat portion into contact with the display medium provided on a supporting base, at least one of the display medium or the flat portion of the heat application member having an elastically deformable portion through which one of the display medium or the flat portion of the heat application member performs elastic deformation and the display medium is capable of coming into close contact with the heat application member.
摘要:
An image recording method for recording information in and erasing recorded information from a display medium which contains a reversible thermosensitive recording material capable of writing information therein and erasing recorded information therefrom by the application of heat thereto, by using a heat application member with round corners, and contacting the surface of the heat application member with the display medium.
摘要:
There is disclosed a method of successively forming and/or erasing images selectively in different portions of a recording layer of a recording medium which comprises a reversible thermosensitive recording material capable of recording images and erasing the same by reversibly changing the transparency or the color tone of the portions of the recording layer with the application of heat thereto, depending upon the temperature thereof, in such a manner that the same portion of the recording layer is not continuously used for image formation and/or erasure in excess of a predetermined number of times, thereby repeating the use of the recording medium for an extended period of time.
