Ink-jet inks including inter-crosslinkable latex particles

#There are several reasons that ink-jet printing has become a popular way of recording images on various media surfaces, particularly paper and photo media substrates. Some of these reasons include low printer noise, capability of high-speed recording, and capability of multi-color recording. Additionally, these advantages can be obtained at a relatively low price to consumers. With respect to ink-jet ink chemistry, the majority of commercial ink-jet inks are water-based. Thus, their constituents are generally water-soluble, as in the case with many dyes, or water dispersible, as in the case with pigments. Furthermore, ink-jet inks have low viscosity to accommodate high frequency jetting and firing chamber refill processes common to thermal ink-jet architecture.

#As ink-jet ink applications have advanced, improvement of such printing systems through ongoing research and developmental efforts continue to be sought.

#Additional features and advantages of the invention will be apparent from the detailed description which follows, taken in conjunction with the accompanying drawings, which together illustrate, by way of example, features of the invention; and, wherein:

#FIG. 1 is a photograph of the result of a window cleaner test of the control ink sample described in Example 4;

#FIG. 2 is a photograph of the result of a dry rub test of the control ink sample described in Example 4;

#Reference will now be made to the exemplary embodiments illustrated, and specific language will be used herein to describe the same. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended.

#Before the present invention is disclosed and described, it is to be understood that this disclosure is not limited to the particular process steps and materials disclosed herein because such process steps and materials may vary somewhat. It is also to be understood that the terminology used herein is used for the purpose of describing particular embodiments only. The terms are not intended to be limiting because the scope of the present disclosure is intended to be limited only by the appended claims and equivalents thereof.

#It must be noted that, as used in this specification and the appended claims, the singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise.
