Abstract

A coating liquid includes a polymer particle, an aggregating agent for a coloring material, a nonionic surfactant having an HLB value within the range of 15.5 to 20, and water.

First claim

What is claimed is:

1. A coating liquid comprising:
a polymer particle;
an aggregating agent for a coloring material;
a first nonionic surfactant having an HLB value within the range of 15.5 to 20;
a second nonionic surfactant with an HLB value of less than 15.5; and
water,
wherein a weighted average of the HLB value of the first nonionic surfactant and the second nonionic surfactant is 14.5 or greater.

2. The coating liquid according to claim 1 ,
wherein the aggregating agent for a coloring material is at least one selected from the group consisting of an inorganic acid and an inorganic acid salt.

3. The coating liquid according to claim 1 ,
wherein a content of the first nonionic surfactant is in a range of 10% by weight to 200% by weight, with respect to the weight of the aggregating agent for a coloring material.

4. The coating liquid according to claim 2 ,
wherein a content of the first nonionic surfactant is in a range of 10% by weight to 200% by weight, with respect to the weight of the aggregating agent for a coloring material.

5. A recording medium comprising:
a non-permeable base material; and
a coating layer that is to be image-recorded with a water-based ink, and is formed on the non-permeable base material by using the coating liquid according to claim 1 .

6. The recording medium according to claim 5 ,
wherein the non-permeable base material is a resin film.

7. A recording medium comprising:
a non-permeable base material; and
a coating layer that is to be image-recorded with a water-based ink, is disposed on the non-permeable base material, and contains a polymer, an aggregating agent for a coloring material, a first nonionic surfactant having an HLB value within the range of 15.5 to 20, and a second nonionic surfactant with an HLB value of less than 15.5, wherein a weighted average of the HLB value of the first nonionic surfactant and the second nonionic surfactant is 14.5 or greater.

8. The recording medium according to claim 7 ,
wherein the non-permeable base material is a resin film.

9. The coating liquid according to claim 1 ,
wherein a content of the second nonionic surfactant is in a range of 0.05% by weight to 5% by weight with respect to the weight of the coating liquid.
