Abstract
A method of forming a coating on a web. A coating mixture includes a continuous phase of a first material and a second material contained in microcapsules. The first material and the second material interact to form the coating. The coating mixture is applied to a face of the web. The web is passed between a back-up member and a doctor blade so that the doctor blade levels the coating mixture on the web and crushes the microcapsules to cause mixing of the materials on the web to form the coating on the web.
