Abstract
Official abstract text for this publication.
A pigment dispersion containing a metal pigment, wherein the metal pigment contains plate-like particles, and in the case where the longitudinal diameter on the planar surface of the plate-like particle is X, the lateral diameter is Y, and the thickness is Z, the 50% average particle diameter R50 of a corresponding circle determined from the surface area in the X-Y plane of the plate-like particle is between 0.5 and 3 μm, and the condition R50/Z>5 is satisfied.
First claim
Opening claim text (preview).
The invention claimed is: 1. A pigment dispersion comprising a metal pigment, wherein the metal pigment contains plate-like particles, and in the case where the longitudinal diameter on the planar surface of the plate-like particle is X, the lateral diameter is Y, and the thickness is Z, a maximum particle diameter Rmax of a corresponding circle determined from the surface area in the X-Y plane of the plate-like particles is 10 μm or less, wherein an average thickness of the metal pigment is less than 0.03 μm. 2. The pigment dispersion according to claim 1 , wherein the metal pigment is aluminum or an aluminum alloy. 3. The pigment dispersion according to claim 1 , further comprising a resin. 4. The pigment dispersion according to claim 3 , wherein the resin is at least one type of resin selected from a group consisting of a polyvinyl alcohol, polyvinyl butyral, polyethylene glycol, polyacrylic acid, polyacrylamide, cellulose derivative, acrylate polymer, and modified nylon resin. 5. The pigment dispersion according to claim 1 , wherein the metal pigment contains a silicon oxide layer. 6. An ink composition comprising the pigment dispersion according to claim 1 , and an organic solvent.
