Abstract
A nonaqueous ink, having: colorant particles, the colorant particles having an average particle diameter of 1 nm or more and less than 50 nm, and the value (D90−D10) of being 100 nm or less, a dispersant; and a cationically-polymerizable compound; wherein D90−D10 is a value obtained by subtracting D10 from D90; D90 and D10 represent respectively the particle diameters at cumulative colorant particle numbers of 0.9 (90 number %) and 0.1 (10 number %) in an integral value of the distribution function dG=F(D)dD; and G represents the number of the pigment particles; and D represents the diameter of the particles.
Claims12
A nonaqueous ink, comprising:
- colorant particles, the colorant particles having an average particle diameter of 1 nm or more and less than 50 nm, and the value (D90−D10) of being 100 nm or less,
- a dispersant;
- and
- a cationically-polymerizable compound;
- wherein D90−D10 is a value obtained by subtracting D10 from D90;
- D90 and D10 represent respectively the particle diameters at cumulative colorant particle numbers of 0.9 (90 number %) and 0.1 (10 number %) in an integral value of the distribution function dG=F(D)dD;
- and G represents the number of the pigment particles;
- and D represents the diameter of the particles.
A method of producing a nonaqueous ink, the nonaqueous ink containing a dispersant and, a cationically-polymerizable compound, comprising the steps of:
- providing a colorant solution and an aqueous medium, in which a dispersant is contained in at least one of the colorant solution and the aqueous medium;
- bringing the colorant solution and the aqueous medium into contact each other, and thereby precipitating the colorant as fine particles;
- removing the fine particles in an agglomerate form, and
- bringing the removed colorant agglomerates into contact with an organic medium.
