Abstract

This coating liquid contains: aerogel particles; a water-soluble polymer having a hydrophobic group; a binder resin; and a liquid medium, wherein the water-soluble polymer comprises a cellulose based resin having an alkyl group having 6 to 26 carbon atoms. The coating liquid is capable of forming a coating film having a high filling rate of aerogel particles and an excellent film strength and is excellent in terms of the dispersibility of aerogel particles.

Claims (8)

1. A coating liquid, comprising:

aerogel particles;

a water-soluble polymer having a hydrophobic group;

a binder resin; and

a liquid medium comprising water,

wherein the water-soluble polymer comprises a cellulose-based resin having an alkyl group having 6 to 26 carbon atoms.

2. The coating liquid according to claim 1 ,

wherein a content of the aerogel particles is 70 vol % or more based on a total volume of a solid content.
