摘要:
It is an object of the present invention to provide an ink composition using a metal phthalocyanine type cyan dye, according to which the indoor storability (gas resistance) of images created using the ink composition can be improved. The present invention provides an ink composition containing water, metal phthalocyanine type cyan dye, and aromatic compound having a sulfo group and/or salt thereof represented by undermentioned general formula (1) and/or (2). Moreover, the present invention provides an ink jet recording method comprising carrying out recording by discharging droplets of an ink composition and attaching the droplets to a recording medium, wherein the ink jet recording method uses an ink composition as described above as the ink composition. Furthermore, the present invention provides a recorded article characterized by being obtained by recording using an ink composition as described above. (In the formula, M1 represents a counter ion forming a salt, X represents an integer from 1 to 3, and R1 and R2 each represents a hydrogen atom, an alkyl group having 1 to 6 carbon atoms or an alkoxy group having 1 to 6 carbon atoms, and R1 and R2 may be the same or different.) (In the formula, M2 represents a counter ion forming a salt, Y represents an integer from 1 to 4, and R3 and R4 each represents a hydrogen atom, an alkyl group having 1 to 6 carbon atoms or an alkoxy group having 1 to 6 carbon atoms, and R3 and R4 may be the same or different.)
摘要:
An object of the present invention is to provide an ink composition that can improve the preservation characteristics (gas fastness) of an image produced by an ink composition which uses phthalocyanine group cyan dye. The present invention provides an ink composition wherein at least water, the phthalocyanine group cyan dye indicated by the general formula (I), and an aromatic compound having a sulfone group and/or the salt thereof represented by the general formulae (a) and/or (b) are contained; and an ink composition wherein at least water, the phthalocyanine group cyan dye indicated by the general formula (VIII), and an aromatic compound having a sulfone group and/or the salt thereof represented by the general formulae (a) and/or (b) are contained. Moreover, the present invention provides an inkjet recording method in which recording is conducted by discharging ink droplets of an ink composition and causing the ink droplets to adhere to a recording medium, wherein as said ink composition, the aforementioned ink composition is used. Further, the present invention provides a record which is obtained by using the aforementioned ink composition.

A composition, for ink jet recording, containing a cationic, water-soluble resin comprising a repeating unit represented by the following formula (I) can realize an image possessing excellent waterproofness and lightfastness and having no significant feathering or bleeding, especially no significant color-to-color bleeding: wherein R1 and R2 which may be the same or different represent a hydrogen atom or a C1-5 alkyl group, provided that R1 and R2 do not simultaneously represent a hydrogen atom; and n is 0, 1, or 2.
摘要:
An air suction device for a diesel engine having a throttle valve disposed within an air suction passage wherein the throttle valve has an opening through which air may pass even when the throttle valve is in a closed position and wherein a mechanism is positioned adjacent that hole to selectively control the amount of air passing through that hole when the throttle valve is in a closed position.
摘要:
A fluid control system for cleaning exhaust gases of an internal combustion engine by injecting additional air into the exhaust manifold of the downstream of the combustion chamber of the engine according to the engine operating conditions. This system includes a vacuum control valve which supplies vacuum on-off signals to a flow control valve device which meters injecting of additional air. The vacuum control valve device includes a housing, a diaphragm dividing the housing into a first chamber communicating with the engine intake manifold which forms a vacuum source and a second chamber communicating with atmosphere, a valve assembly securely fixed to a center portion of the diaphragm and having a passage intercommunicating the first and second chambers and a valve body normally closing the intercommunicating passage, a solenoid device provided in the second chamber for on-off driving of the diaphragm in response to on-off signals, and a stopper adapted to open the intercommunicating passage by pressing the valve body when the valve assembly is displayed by a predetermined distance for feeding vacuum signals proportional to the engine load from an output port of the housing to a flow control valve when on-off signals are supplied to the solenoid device.
