Abstract
A transfer article that includes a liner with multi-sized particles disposed thereon, wherein the multi-sized particles include a plurality of dominant hydrophilic particles having an average primary particle size of no greater than 200 microns, and a plurality of discrete hydrophobic nanoparticles.
Claims19
A transfer article comprising:
- a first flexible liner having opposing first and second surfaces, wherein the first surface has a release value of less than 700 grams per inch per ASTM D3330/D3330M-04;
- multi-sized particles adhered to the first surface of the first flexible liner;
- the multi-sized particles comprising:
- a plurality of dominant hydrophilic particles having an average primary particle size of no greater than 200 microns;
- and
- a plurality of discrete hydrophobic nanoparticles;
- wherein the dominant particles are disposed in a monolayer;
- and
- a second flexible liner having opposing first and second surfaces, wherein the second liner is in physical contact with at least a portion of the multi-sized particles.
