Abstract: A colored resin particle dispersion and an ink are provided which yield excellent abrasion resistance for printed items. Moreover, a colored resin particle dispersion and an inkjet ink are provided which exhibit excellent abrasion resistance, water resistance and marker resistance, as well as favorable storage stability. Specifically provided are a colored resin particle dispersion containing colored resin particles, a basic dispersant, and a non-aqueous solvent, wherein the colored resin particles include a colorant and a crosslinked solid resin, and an inkjet ink containing this colored resin particle dispersion.

Abstract: A colored resin particle dispersion and an ink are provided which exhibit excellent abrasion resistance of the printed items and excellent storage stability of the dispersion. Specifically provided is a colored resin particle dispersion comprising colored resin particles containing a colorant and a solid resin, a basic dispersant, and a non-aqueous solvent, wherein the solid resin is a resin having alkoxy groups and/or a polysilsesquioxane. The resin having alkoxy groups preferably has methoxy groups and/or ethoxy groups. Further, the resin having alkoxy groups preferably contains at least one of a polyamide resin having methoxymethyl groups, a methoxypolysilsesquioxane and an ethoxypolysilsesquioxane.

Abstract: A colored resin particle dispersion and an ink are provided which exhibit excellent color development and abrasion resistance. Moreover, a colored resin particle dispersion and an inkjet ink are provided which exhibit excellent color development and abrasion resistance, together with excellent water resistance and marker resistance. Specifically provided are a colored resin particle dispersion containing colored resin particles, a basic dispersant, and a non-aqueous solvent, wherein the colored resin particles contain a colorant, and a phosphorylated solid resin and/or a nitrated solid resin. The phosphorylated solid resin may include a phosphorylated polyvinyl alcohol and/or a phosphorylated polyvinyl acetal, and the nitrated solid resin may include a nitrocellulose.

Abstract: A non-aqueous pigment ink is provided, wherein the non-aqueous pigment ink comprises an alkyl (meth)acrylate copolymer containing an alkyl (meth)acrylate unit having an alkyl group of 12 or more carbon atoms and a (meth)acrylate unit having a pyridyl group, a pigment, and a non-aqueous solvent.

Abstract: A non-aqueous ink comprising a carbon black and a non-aqueous solvent is provided, wherein the carbon black comprises: a carbon black (A) having a primary particle size of at least 18 nm but less than 30 nm, a DBP absorption of at least 80 cm3/100 g but not more than 130 cm3/100 g and a pH of at least 6.0 but not more than 9.0, and a carbon black (B) having a primary particle size of at least 30 nm but not more than 50 nm, a DBP absorption of at least 40 cm3/100 g but less than 80 cm3/100 g and a pH of at least 6.0 but not more than 9.0.
