Abstract: The present disclosure provides pre-treatment coatings, media substrates, and related methods. As such, a pre-treatment coating can include an evaporable solvent, a matrix, and a wax. The matrix can include a binder and a fixer, and the wax can include wax particles dispersed within the matrix. At least a portion of the wax particles can have a particle size that is greater than a thickness of the matrix when the pre-treatment coating is applied to a media substrate at a basis weight from 0.5 gsm to 20 gsm and the evaporable solvent removed.
