Abstract

A method of coating a support (1) with microcapsules, especially in manufacturing pressure-sensitive recording paper, by dispensing hydrophobic-walled microcapsules in water, applying the dispersion to the support (1) and removing excess dispersion by passing the support (1) past a flexible blade (5) thereby also to spread and smooth the coating.
