摘要： Provided is a composition that can form a coating film having excellent surface smoothness and high heat deformation resistance in a coating liquid for a paint mainly containing a polymer, an ink, an adhesive, and an anode, a cathode, or a separator of a lithium ion battery, for example. A coating liquid composition includes a filler, a solvent, a dispersant, and a thickener. When the coating liquid composition is applied to a substrate to form a coating film having a thickness of 0.5 to 20 μm, the coating film has a shrinkage rate of 15.0% or less after heating at 170° C. for 15 minutes.
