A method for forming fine concavo-convex patterns by using a relief formation materialhaving a relief formation layercomposed of a resin having thermoplasticity and a relief pattern sheethaving on a surface thereof fine concavo-convex patterns, wherein a photothermal conversion layeris formed in the relief formation materialor the relief pattern sheet; the photothermal conversion layeris irradiated with lightto make the photothermal conversion layergenerate heat in the state that the relief formation layeris brought into contact with the fine concavo-convex patterns; and the fine concavo-convex patternsare formed on the relief formation layer

Method for forming fine concavo-convex patterns, method for producing optical diffraction structure, and method for copying optical diffraction structure

An image forming method is provided to attain a higher security for preventing forgery and falsification of information by using an optical diffraction structure. In a body () whereupon a layer is to be transferred, printing information () is recorded. On the body (), a layer () including a hologram and a diffraction lattice provided on an optical diffraction structure transfer sheet () is transferred, and an image including recorded printing information () and optical diffraction structures () is formed. The layer () including the optical diffraction structure is transferred so that the diffraction lattice () to be transferred forms diffraction lattice information () showing a prescribed regularity in a corresponding relationship between the printing information ().

Image forming method and recorded matter

A receiving layer transfer material which represents a free combination of a hologram and an image of various colors by an on-demand printing system such as thermal transfer method, onto a transfer layer which is transferred onto an object. The receiving layer transfer material is provided with a release layer, a relief forming layerhaving a reflection layerat a relief forming side and having a visual effect, and an adhesive layer, which are sequentially stacked on one surface of a substrate

Receptor layer transfer material, transfer sheet, and coloring material receptor sheet with relief layer, and image forming method using the same

An image display body in which a decorative effect is obtained more effectively by an optical diffraction structure. In an image display body, an optical diffraction structure portion constituted by the optical diffraction structure in a halftone dot state is provided in a colored region on a base material. In the image display body, a dot area percent of a halftone dot a constituting the optical diffraction structure portion to the colored region ranges from 15% to 60%, an area of each halftone dot a is smaller than 0.25 mm. The halftone dotsare diffused by an error diffusion method.

Image display body and image formation method

A photoresist film which can form an even fluorescent substance layer, in intimate contact with the surface of cells, in a simplified manner, and a back plate of PDP using the film are provided. More specifically, a photoresist film comprising a base film and, provided on the base film, a photosensitive resin composition layer comprising a fluorescent substance, a photosensitive resin, and a volatile organic material, and a process for producing a back plate of PDP using the film are provided.

Photoresist film and process for producing back plate of plasma display

In the provision of a color filter on a front plate comprising a substrate 1, electrodes (4, 5) provided on the substrate, a dielectric layer 6 provided on the electrodes, and a protective layer 7 provided on the dielectric layer, a specific color filter is provided on the substrate 1, between the electrode 5 and the first dielectric layer 6a, or between the first dielectric layer 6a and the second dielectric layer 6b, or between the second dielectric layer 6b and the protective layer 7. By virtue of this constitution, troubles, such as breaking or unacceptable shape of edge, are not caused in the formation of the electrodes.

Plasma display panel

A plasma display panel includes a front plate having a substrate (1), a transparent electrode (4) and a bus electrode (5) disposed on the substrate, a dielectric layer (6) disposed on the electrodes (4,5), and a protective layer (7) disposed on the dielectric layer (6). A color filter is provided either on the substrate (1), between the electrode (5) and a first dielectric layer (6a), between the first dielectric layer (6a) and a second dielectric layer (6b), or between the second dielectric layer (6b) and the protective layer (7). The present invention provides for stable formation of a color filter and eliminates breakage of the electrodes (4,5).
