## 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.

## Claims

### Claim 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.

### Claim 2 (depends on 1)

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.

### Claim 3 (depends on 1)

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.

### Claim 4 (depends on 2)

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.

### Claim 5 (depends on 1)

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.

### Claim 6 (depends on 5)

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

### Claim 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.

### Claim 8 (depends on 7)

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

### Claim 9 (depends on 1)

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.
