Patent

CA 2598871

Composition and methods for replication are described. A method includes: providing a first submaster having a first topography; providing a carrier having a first side and a second side coating the first side with a first resin having a first viscosity; pressing the first topography against the first resin: replicating the first topography in the first resin as a first replica surface; increasing the first viscosity; releasing the first replica surface from the first topography; providing a second submaster having a second topography; coating the second side with a second resin having a second viscosity, pressing the second topography against the second resin; replicating the second topography in the second resin as a second replica surface; increasing the second viscosity; and releasing the second replica surface from the second topography. The composition and methods provide advantages in that surface topography is replicated with enhanced overall cost effectiveness.
