AQUEOUS INK, INK JET RECORDING METHOD AND INK JET RECORDING APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240123749 titled 'AQUEOUS INK, INK JET RECORDING METHOD AND INK JET RECORDING APPARATUS

Simplified Explanation

The aqueous ink for ink jet described in the patent application is capable of recording images with high abrasion resistance while maintaining a consistent glossy feeling on the recorded surfaces even when rubbed against each other. The ink contains a wax, a nonionic dispersant, and an anionic dispersant.

• The nonionic dispersant in the ink is a compound with a HLB value of 9.0 or more to 18.0 or less, represented by the general formula (1).
• The anionic dispersant in the ink is a compound with at least one type of anionic group such as a sulfonic acid group, a carboxylic acid group, or a phosphoric acid group.

Potential Applications

The technology described in this patent application could be applied in various industries such as commercial printing, industrial printing, packaging, and labeling.

Problems Solved

This technology solves the problem of maintaining abrasion resistance in printed images while also preserving the glossy feeling of the recorded surfaces when rubbed against each other.

Benefits

The benefits of this technology include enhanced durability of printed images, improved aesthetic quality, and increased versatility in printing applications.

Potential Commercial Applications

The potential commercial applications of this technology include printing of labels, packaging materials, marketing materials, and other high-quality printed products.

Possible Prior Art

One possible prior art for this technology could be the use of wax-based inks in printing applications, but the specific combination of nonionic and anionic dispersants for achieving both abrasion resistance and glossy feeling may be a novel innovation.

How does this technology compare to existing abrasion-resistant inks in terms of durability and glossiness?

This article does not provide a direct comparison with existing abrasion-resistant inks in terms of durability and glossiness. Further research or testing may be needed to evaluate the performance of this technology against existing alternatives.

What are the potential environmental impacts of using this aqueous ink compared to traditional solvent-based inks?

The article does not address the potential environmental impacts of using this aqueous ink compared to traditional solvent-based inks. A comprehensive life cycle assessment or environmental impact study may be necessary to evaluate the sustainability of this technology.

Original Abstract Submitted

provided is an aqueous ink for ink jet capable of recording an image, which has abrasion resistance required in a commercial printing field and an industrial printing field and which is suppressed from being changed in glossy feeling when recorded matters are loaded and their recorded surfaces are rubbed against each other. the aqueous ink for ink jet includes a wax, (i) a nonionic dispersant for dispersing the wax and (ii) an anionic dispersant for dispersing the wax. the nonionic dispersant is a compound represented by the general formula (1) and has a hlb value of 9.0 or more to 18.0 or less. the anionic dispersant is a compound having at least one kind of anionic group selected from the group consisting of: a sulfonic acid group; a carboxylic acid group; and a phosphoric acid group.
