Abstract
Methods of forming patterned coatings are disclosed. The methods include the steps of disposing a composition onto a substrate to form a liquid coating on the substrate and removing or providing energy through a first pattern of areas on the liquid coating to form a topographically patterned coating, the topographical pattern corresponding to the first pattern of areas.

A method of forming a topographically patterned coating comprising the steps of:
- disposing a composition onto a substrate to form a liquid coating on the substrate;
- removing energy through a first pattern of areas on the liquid coating to form a topographically patterned coating, the topographical pattern corresponding to the first pattern of areas.
A method of forming a topographically patterned coating comprising the steps of:
- disposing a composition onto a substrate to form a liquid coating on the substrate;
- providing energy from an energy source through a first pattern of areas on the liquid coating to form a topographically patterned coating, the topographical pattern corresponding to the first pattern of areas, and the coating being disposed between the substrate and the energy source.
A method of forming a topographically patterned coating comprising the steps of:
- disposing a composition onto a substrate to form a liquid coating on the substrate;
- disposing the substrate on an energy transfer surface, the energy transfer surface being substantially smooth;
- providing energy from an energy transfer surface through a first pattern of areas on the liquid coating to form a topographically patterned coating, the topographical pattern corresponding to the first pattern of areas.
A method of forming a topographically patterned coating comprising the steps of:
- disposing a pressure sensitive adhesive forming composition onto a substrate to form a liquid coating on the substrate;
- providing energy through a first pattern of areas on the liquid coating to form a topographically patterned coating, the topographical pattern corresponding to the first pattern of areas.
A method of forming a topographically patterned coating comprising the steps of:
- disposing a composition comprising nanoparticles onto a substrate to form a liquid coating on the substrate;
- providing energy through a first pattern of areas on the liquid coating to form a topographically patterned coating, the topographical pattern corresponding to the first pattern of areas.
