Ink for inkjet recording apparatus, and image forming method

#This application is based upon and claims the benefit of priority from the corresponding Japanese Patent Application No. 2011-167670, filed in the Japan Patent Office on Jul. 29, 2011, the entire contents of which are incorporated herein by reference.

#The present disclosure relates to an ink for an inkjet recording apparatus, and to an image forming method.

#In recent years, inkjet recording apparatuses that form images by an inkjet recording system are widely used as image forming apparatuses since high-definition image qualities that are comparable to those of silver halide photographs can be obtained due to rapid advances in recording technologies.

#FIG. 1 is a cross-sectional view showing the structure of an inkjet recording apparatus including a line head-type recording system.

#FIG. 2 is a plane view in which the conveyor belt of the inkjet recording apparatus shown in FIG. 1 is seen from the upper side.

#FIG. 3 is a block diagram showing the structure of an inkjet recording apparatus including a line head-type recording system.

#Hereinafter exemplary embodiments of the present disclosure are explained in detail, but the present disclosure is not limited at all to the following exemplary embodiments and may be carried out with appropriately making a change suitably within the scope of the object of the present disclosure. For some parts on which explanations are overlapped, one of the explanations is suitably omitted, which is not construed to limit the gist of the disclosure.

#The first exemplary embodiment relates to an ink for an inkjet recording apparatus including at least water, a pigment, a high penetrating agent, a penetrating agent and a moisturizing agent, which includes an alkyl-substituted 1,3-hexanediol or an alkyl-substituted 1,3-pentanediol each having 8 carbon atoms as the high penetrating agent and includes a C1-C4 monoalkyl ether of a polyhydric alcohol, a C6-C8 monoalkyl ether of a polyhydric alcohol, or a polyhydric alcohol dibutyl ether as the penetrating agent, in which the content of the high penetrating agent and the total amount of the contents of the high penetrating agent and penetrating agent are each within a specific range, and which includes specific amounts of glycerin and 1,3-propanediol as the moisturizing agent.

#The ink for an inkjet recording apparatus (hereinafter also simply described as “ink”) according to the first exemplary embodiment may optionally include a dissolution stabilizer that stabilizes the dissolution state of the components included in the ink. Hereinafter the water, pigment, high penetrating agent, penetrating agent, moisturizing agent and dissolution stabilizer which are the essential or optional components included in the ink for an inkjet recording apparatus, and the method for the production of the ink for an inkjet recording apparatus will be explained in order.
