Abstract

Official abstract text for this publication.

A recording medium has a base, a first ink receiving layer, and a second ink receiving layer that is the outermost layer in the stated order, in which the first ink receiving layer is a layer adjacent to the second ink receiving layer, the first ink receiving layer contains fumed silica, the second ink receiving layer contains colloidal silica and resin particles, and the area in which the colloidal silica exists in the recording medium surface is 10% or more and 70% or less.

First claim

Opening claim text (preview).

What is claimed is: 1. A recording medium, comprising: a base, a first ink receiving layer, and a second ink receiving layer that is an outermost layer in the stated order, wherein the first ink receiving layer is a layer adjacent to the second ink receiving layer, the first ink receiving layer contains a fumed silica, the second ink receiving layer contains a colloidal silica and a polymer particle, and an area in which the colloidal silica exists in a surface of the recording medium is 10% or more and 70% or less. 2. The recording medium according to claim 1 , wherein an average primary particle size of the colloidal silica is 20 nm or more and 100 nm or less. 3. The recording medium according to claim 1 , wherein a content of the colloidal silica in the second ink receiving layer is 0.015 g/m 2 or more and 0.030 g/m 2 or less. 4. The recording medium according to claim 1 , wherein an average particle size of the resin particle measured by a dynamic light scattering method is 20 nm or more and 100 nm or less. 5. The recording medium according to claim 1 , wherein a glass transition temperature of the resin particle is 5° C. or more and 75° C. or less. 6. The recording medium according to claim 1 , wherein a content of the resin particle in the second ink receiving layer is 0.005 g/m 2 or more and 0.1 g/m 2 or less. 7. The recording medium according to claim 1 , wherein a content (g/m 2 ) of the resin particle in the second ink receiving layer to the content (g/m 2 ) of the colloidal silica is 0.2 times or more and 0.7 times or less. 8. The recording medium according to claim 1 , wherein the resin particle is a urethane resin particle. 9. The recording medium according to claim 1 , wherein the second ink receiving layer contains a zirconium compound.
