PROBLEM TO BE SOLVED: To provide an ultraviolet(UV) ray-curable adhesive comprising a UV ray-curable adhesive layer laminated on the surface of a sheet substrate without an increase of viscosity during its storing, the UV ray adhesive layer of which can be cured by a UV ray irradiation, and the adhesive sheet made by using the adhesive. SOLUTION: The ultraviolet ray-curable adhesive containing a photopolymerization initiator microcapsule does not increase the viscosity during its storing, when destroying, by pressing or the like, the microcapsule contained in the adhesive layer of the adhesive sheet made by laminating the adhesive layer by applying the adhesive to a given part on the sheet substrate, or when irradiating it with the UV ray, after improving permeability of the photopolymerization initiator by pressing/heating/humidifying or the like without destroying the microcapsule, the adhesive layer can be cured.

PROBLEM TO BE SOLVED: To produce a conductive circuit on demand by using an electrophotographic system instead of printing. SOLUTION: Using toner containing a conductive agent and developer, the conductive circuit is formed by the electrophotographic system. In the electrophotographic system, images, such as letters, figures, etc., for communicating information are formed by fixing developer to a support such as paper. Developer is roughly classified into two-component developer containing toner and the other particles (carrier) which applies charges to toner, and one-component developer composed of only toner having the ability to control charges. In such developers, toners are color particles having electrifying functions, and each toner is composed of binding resin, a coloring material, a charge control agent, a releasing agent, a surface treatment agent, and a magnetic agent. The types of such toner components and the amounts of the components to be blended are carefully optimized. This toner realizes satisfactory balance between performances required for the toner, such as electrostatic charging property, electric resistance, development characteristics such as magnetism and fluidity, fixing characteristics such as fixing property and coloring property, preservability, handling, etc. COPYRIGHT: (C)2004,JPO

PROBLEM TO BE SOLVED: To produce a peelable electric conduction circuit on demand by using an electrophotographic system instead of printing. SOLUTION: Toner containing a conductive agent and a peeling agent and developer are used. The electric conduction circuit is formed by the electrophotographic system. Processing is provided for forming the electric conduction circuit on a peelable sheet by the electrophotographic system using conductive peelable developer containing the above described conductive peelable toner or such conductive peelable developer. In addition, processing is provided for superimposing the face of the peelable sheet on which the electrical conduction circuit is formed and the adhesive face of an adhesive sheet, thereby transferring the electric conduction circuit to the adhesive face. Since the toner and the developer are conductive and peelable, the circuit thus obtained is also conductive and easily peelable. Therefore, the circuit can be produced on demand by the electrophotographic system instead of printing that needs a plate. COPYRIGHT: (C)2004,JPO
