Image forming method
View Patent ↗A color particle is disclosed, comprising a color-exhibitive piece which comprises microparticles for structural color and a matrix and is dispersed in a binder resin, wherein the color particle meets the following requirement: 1.5≦ A/B ≦5.0 wherein A is a major axis diameter of the color particle and B is a minor axis diameter of the color particle; and an angle of a longitudinal direction of the color-exhibitive piece to a major axis direction of the color particle falls within a range of ±20 degrees.
1. A color particle, comprising:
a color-exhibitive piece which comprises microparticles for structural color and a matrix, the microparticles being in a periodic structure in the matrix; and
the color-exhibiting piece is dispersed in a binder resin,
wherein
the color particle meets the following requirement:
1.5≦ A/B ≦5.0
wherein A is a major axis diameter of the color particle and B is a minor axis diameter of the color particle; and
an angle of a longitudinal direction of the color-exhibitive piece to a major axis direction of the color particle falls within a range of ±20 degrees.
2. The color particle of claim 1 , wherein the major axis diameter of the color particle is from 1 to 100 μm.
3. The color particle of claim 1 , wherein the color particle contains the color-exhibitive piece in an amount of 0.1 to 50% by mass.
4. The color particle of claim 1 , wherein the color-exhibitive piece has a major axis diameter (a) of 1 to 75 μm and a minor diameter (b) of 0.5 to 50 μm.
5. The color particle of claim 1 , wherein the binder resin contains a colorant.
6. An image forming method comprising forming an image by using a color particle comprising a color-exhibitive piece which comprises microparticles for structural color and a matrix and is dispersed in a binder resin, wherein the color particle meets the following requirement:
1.5 ≦A/B≦ 5.0
wherein A is a major axis diameter of the color particle and B is a minor axis diameter of the color particle; and an angle of a longitudinal direction of the color-exhibitive piece to a major axis direction of the color particle falls within a range of ±20 degrees.
7. The image forming method of claim 6 , wherein the major axis diameter of the color particle is from 1 to 100 μm.
8. The image forming method of claim 6 , wherein the color particle contains the color-exhibitive particle in an amount of 0.1 to 50% by mass.
9. The image forming method of claim 6 , wherein the color-exhibitive piece has a major axis diameter (a) of 1 to 75 μm and a minor diameter (b) of 0.5 to 50 μm.
10. The image forming method of claim 6 , wherein the binder resin contains a colorant.
