  • Publication number: 20130220171
    Abstract: [Problem to be solved] A non-aqueous pigment ink is disclosed, which can eliminate or reduce striking through while ensuring pigment dispersion stability and ejection stability, and achieve high print density. Also, a non-aqueous inkjet ink is disclosed, which can reduce the time required for warming up the ink while ensuring the pigment dispersion stability and the ejection stability. [Solution] As the first aspect, the non-aqueous pigment ink contains at least a non-aqueous solvent and a pigment that is self-dispersed in the solvent, wherein the self-dispersed pigment is treated with a compound represented by R1—X or R2—Y—R3, where X is any of —SH, —NCO, —NH2 and —NHR (where R is an alkyl group), Y is any of —CO—O—O—CO— and —CO—O—O—, R1, R2 and R3 are alkyl groups with a carbon number of 8-22, the alkyl groups may be linear or branched, and R2 and R3 may be the same with or different from each other.

  • Patent number: 8497317
    Abstract: A method of producing a polyurethane resin-bonded pigment aqueous dispersion includes causing (I) a pigment having a surface acidic group to come in contact with (II) a basic compound having two or more amino groups selected from a primary amino group and a secondary amino group in its molecule in an aqueous medium so that the pigment has an unreacted surface amino group, and causing the pigment to come in contact and react with (III) a polyurethane resin having an isocyanate end group. A polyurethane resin-bonded pigment aqueous dispersion produced by the method exhibits excellent image density, dispersibility, and storage stability.
