Embodiment approach

[0049] A composition for forming an ink-receiving layer of a recording medium of an image forming device according to an exemplary embodiment of the present invention includes a fixing agent, an inorganic filler, a binder, and a solvent.

[0050] The fixative is preferably a polymeric material, such as an acrylate cationic latex comprising an ultraviolet (UV)-absorbing component in a polymeric structure. As the cationic latex containing a UV-absorbing component, any component having a cationic-based polymeric structure containing a UV-absorbing component can be used as the UV-absorbing component.

[0051] The cationic latex used as a fixing agent according to an exemplary embodiment of the present invention comprises a component unit having a cationic group, a component unit serving as a crosslinking agent during copolymerization, a component unit having no ionic character, and a component unit having an active UV-absorbing group. component units.

Abstract

A composition for an ink acceptable layer has excellent light resistance and discoloration resistance while maintaining improved ink fixation properties and glossiness. A recording medium for an image forming apparatuses using the composition, and a method for preparing the recording medium are also provided. The composition for forming an ink acceptable layer according to an exemplary embodiment includes a fixing agent, an inorganic filler, a binder and a solvent. The fixing agent is a polymeric material containing UV-absorbing constituents.

Description

technical field [0001] The present invention relates to a composition for an ink-accepting layer, a recording medium for an image forming apparatus using the composition, and a method for producing the recording medium. More specifically, the present invention relates to compositions for ink-receptive layers having excellent lightfastness and fade resistance while maintaining improved ink fixing characteristics and gloss. The present invention also relates to a recording medium for an image forming apparatus using the composition, and a method for producing the recording medium. Background technique [0002] Printing methods for imaging devices are mainly classified into two categories: non-impact printing and impact printing. The printing method used for inkjet printers is a non-impact printing method, which has advantages over impact printing including a low noise level and the ability to develop colors more easily than laser beam printers. Furthermore, inkjet printers a...
