摘要:
The invention relates to an image receiving sheet which is a retransfer sheet for forming an image on an optional transferred medium The image receiving sheet comprises a support member, a transparent layer and a thermoplastic fine particles layer Light having an image information is irradiated toward a photosensitive recording medium having microcapsules which change their hardness by being exposed to one of heat or light. Then, a chemical latent image corresponding to the image is represented by the microcapsules having different hardness. When the photosensitive recording medium and the image receiving sheet are superposed and pressed against each other, the unhardened microcapsules are ruptured and the pigment or dye in the unhardened microcapsules flows from the ruptured microcapsules. The pigment or dye that flows from the microcapsules is absorbed into the thermoplastic fine particles layer. As a result, a visible image corresponding to the image is formed on the image receiving sheet. The image receiving sheet is placed on the transferred medium and they are thermally pressed against each other. When the support member is peeled off, the image covered with the transparent layer remains as a transfer on the transferred medium.

In a transfer-type image recording device utilizing a recording medium comprising a continuous-form recording sheet and a cut-form developing sheet, the former is arranged to be fed in a predetermined speed, coated with a plurality of photo and pressure sensitive microcapsules each containing a dye-precursor and a component to change the strength thereof when exposed to light. And the latter is designed to be coated with a developer material which is reactable with the dye-precursor. In the image recording device, a visible image is obtained by transferring an image having been formed on the recording sheet onto a surface of the developing sheet. A roller member for peeling off the microcapsules from a surface of the recording sheet after a transfer operation of an image is executed. Thus, any recognizable image on the recording sheet, for example, a visible negative image formed by the remained microcapsules, is erased after the visible image is obtained on the developing sheet.

An image forming apparatus for forming visible images on a recording medium according to source image information, comprises microcapsules, a stirring roller, a photosensitive drum, a microcapsules coating device, a corotron, an exposing device, a heater and a developing device. Each of the microcapsules includes a chromogenic material and a material having a heat-softening property wherein it is softened by heat and a photocuring property wherein it is cured by light. The stirring roller frictionally charges the microcapsules. The photosensitive drum has an electrically chargeable drum surface, the drum surface permits electrostatic latent image to be formed therein according to the source image information. The microcapsules coating device coates the charged microcapsules onto the drum surface of the photosensitive drum according to the electrostatic latent images. The corotron transfer the microcapsules from the drum surface of the photosensitive drum to the recording medium. The exposing device exposes the microcapsules to a radiation having the source image information, so as to selectively cure the microcapsules according to the source image information. The heater heads the microscapsules so as to soften the microcapsules before the microcapsules the pressed by the developing device. The developing device presses the recording medium so as to rupture the softened microcapsules on the recording medium, whereby the visible images are formed on the recording medium.

In an optical printing system for printing an image on a recording sheet, adopted as the recording sheet is a sheet coated with microcapsules on one surface thereon. Each microcapsule envelopes a first component which changes color when reacts with a second component. The second component may be coated on the recording sheet or may be coated on a separate developing sheet. The microcapsule further envelopes a third component which varies the mechanical strength of microcapsule when light is projected thereto. An image is formed on the recording sheet by selectively exposing a light thereto in accordance with the image to be printed thereon, and the microcapsules on the recording sheet whose mechanical strength is low are then ruptured by rupturing means. Thereby, the visible image is developed. The exposing is carried out by repeating a predetermined-period exposure at a predetermined interval against the same portion of the recording sheet. The printing operation of the printing system is executed by control means in accordance with a predetermined sequence.

A process and system for forming images on a recording sheet, according to source image information as provided on an original, wherein a pressure-sensitive photosensitive sheet is image-wise exposed to a radiation, to form thereon latent images corresponding to the source image information, and a pressure is applied to the image-wise exposed photosensitive sheet, to cause a chemical reaction and thereby develop the latent images into visible images on the recording sheet. The thus pressurized recording sheet is heated so that the chemical reaction is promoted to thereby increase a density of the visible images.

A photo and pressure sensitive recording medium comprising a base sheet, supporting thereon a color developing agent which reacts with a dye precursor to develop color and an adhesive substance with which the recording medium may be adhered to any suitable material or body. The color developing agent may be coated on one surface of the base sheet and adhesive is applied on the other surface of the base sheet. The adhesive substance may be of thermoplastic type or enveloped in microcapsules crushable under pressure. A peel-off sheet may be conted on the adhesive substance. Alternatively, the color developing agent and the adhesive substance may both be supported on one surface of the base sheet, as well as photo-curable microcapsules containing the dye precursor. The adhesive substance may also be enveloped in microcapsules which are ruptured under pressure to flow out the contained adhesive, with which the recording medium is bonded to a general-purpose sheet such as ordinary paper to provide a one-body recorded sheet.
摘要:
A surface inspection method for a steel sheet coated with a resin, includes irradiating the steel sheet with sheet-like light, which has been linearly polarized at a predetermined polarization angle, at an incidence angle different from Brewster's angle of the coating by a predetermined angle or greater; and imaging linearly-polarized light of a polarization angle of 0 degrees at an acceptance angle different from a regular reflection angle of incident light by a predetermined angle. Accordingly, it is not necessary to change the incidence angle and the acceptance angle depending on resin components and it is possible to inspect a substrate steel surface of the steel sheet highly accurately without observing abnormalities in the coating itself.
