Provided here is a release coating composition, comprising of at least one polymer binder and one or more micro-beads, wherein the amount of the micro-beads is in the range of 1 vol % to 85 vol % of the total dry volume of the release coating composition. The release coating composition enables recycling of release liner substrates provides high quality printing and utilizable in self-wound label laminate construction with no liner.
