Shown is an active energy ray-curable coating varnish which is capable of suppressing outward migration from printed matter, and which is capable of simultaneously achieving excellent curability and excellent line applicability, in addition to low yellowing characteristics. The coating varnish contains a (meth)acrylate compound (A) and a photopolymerization initiator (B), wherein at least one compound selected from the group consisting of ethylene oxide-modified pentaerythritol tetraacrylates, ethylene oxide-modified diglycerol tetraacrylates, ethylene oxide-modified trimethylolpropane triacrylates and ethylene oxide-modified ditrimethylolpropane tetraacrylates is used as the (meth)acrylate compound (A), and at least one of 2-hydroxy-1-[4-[4-(2-hydroxy-2-methyl-propionyl)-benzyl]-phenyl]-2-methylpropan-1-one (b1) and oligo[2-hydroxy-2-methyl-1-[4-(1-methylvinyl)phenyl]propanone] (b2) is used as the photopolymerization initiator (B).

Active energy ray-curable coating varnish, and printed matter using same

Shown is an actinic ray-curable offset ink composition for foodstuff and pharmaceutical packaging which maintains superior curability without using a photosensitizer, which despite contributing to better curability (high productivity) tends to suffer from significant outward migration. The ink composition also suppresses outward migration of the monomers and photopolymerization initiators, and exhibits favorable adhesion to substrates.

Actinic ray-curable offset ink composition and printed item obtained therewith

A developer container, which includes an opening and is configured to store developer therein, includes a developer conveyance plate configured to convey the developer. The developer conveyance plate includes a vibration target unit configured to receive a vibration, and conveys the developer in a first direction in which the developer is conveyed toward an opening side, and in a second direction perpendicular to the first direction. The developer is conveyed by the vibration transmitted from the vibration target unit with use of a resultant force generated by adding a conveyance component in the first direction and a conveyance component in the second direction. A maximum acceleration a1 (max) in the first direction that is provided to the developer conveyance plate by the vibration transmitted from the vibration target unit is set to a lower acceleration than a maximum acceleration a2 (max) in an opposite direction from the first direction.

A method, device, system, and program for transaction of contents through a network are provided. In this transaction system, user terminals are configured to allow users to conduct transactions. A user sends a notification that the user hopes to register contents and prescribed items thereof in a data base in a center through the Internet. A Web server in the center registers the contents and the prescribed items thereof sent from the user in the data base. When use or transfer of the contents sent from the user occurs, a token according to the occurrence is sent to a user who hopes to use or transfer of the contents. In the case of accidents concerning contents and tokens, appropriation/compensation is implemented from funds for handling trouble to a user who suffers a loss of benefit. Thereby, it becomes possible to conduct transaction of contents easily and securely, spread around detail of contents extensively, and receive contents promptly which a user hopes to use.
