[0068] Preparation of Sample 1

[0069] Dilution solvent: 45.8 wt% of ion-exchanged water; acidic component: 30 wt% of lactic acid; foaming agent; 1 wt% of myristylaminopropyl betaine (BISTA MAP of Matsumoto Yushi Seiyaku Co., Ltd.) (with ten Four (14) carbons) and 2% by weight of octadecyldimethylglycine betaine (AMPHITOL 86B from KAO Corporation) (with eighteen (18) carbons in the alkyl group); water insoluble fatty acid : 0.2% myristic acid; bubble enhancer: 1 wt% coconut oil fatty acid diethanolamino (1:1) type (Marpon MM from Matsumoto Yushi Seiyaku Co., Ltd.) and 20 wt% propylene glycol.

[0070] Mix all the above ingredients in water to get a mixture. Then, the mixture was heated with hot water and stirred slowly at a temperature of 70° C. for 10 minutes to prepare an image quality improving treatment liquid (Sample 1).

Abstract

An image quality improvement treatment liquid is disclosed that improves quality of an image formed on a medium by reacting with color materials in ink and agglutinating the color materials upon contact with the ink including water and color materials to be ionized in water or color materials to be ionized in water due to absorption with components having ionic characteristics in water. The image quality improvement treatment liquid includes at least one of cationic components and components capable of acidizing water, at least one of nonionic surfactant and amphoteric surfactant as a foaming agent, and water-insoluble fatty acid.

Description

technical field [0001] The present invention generally relates to an image quality improvement treatment liquid, an image quality improvement treatment method, an imaging method, and an imaging apparatus. More specifically, the present invention relates to a method or apparatus in which an image is formed on a recording medium such as a sheet in accordance with image information using ink droplets ejected from an inkjet head, by preventing color bleeding from occurring on the recording medium. ) and feathering (feathering) effects to improve image quality techniques. Background technique [0002] In the inkjet recording technique, the ink is divided into ink droplets by passing the ink through small (jet) nozzles and ejecting the ink onto a recording medium such as a sheet by using, for example, a pressure-on-demand method or a charge control method. This technique is preferably used in various image forming apparatuses such as printers, facsimiles and copiers. It is expec...
