Abstract
A composition comprising a first material and a second material, wherein said first material is cross-linkable by a first cross-linking reaction and said second material is cross-linkable by a second cross-linking reaction, wherein said first cross-linking reaction and said second cross-linking reaction are inducible by a common activator.

A method of making a structure, comprising the steps of:
- i. forming at least one, preferably a plurality of, sacrificial layer(s) on a substrate;
- ii. forming at least one, preferably a plurality of, permanent layer (s) on said substrate or said first sacrificial layer (s);
- and
- wherein said at least one sacrificial layer is derived from a first composition and said at least one permanent layer is derived from at least one second composition;
- and
- wherein said at least one sacrificial layer is formed by a first cross-linking reaction of said first composition and said at least one permanent layer is formed by a second cross-linking reaction of said second composition;
- wherein said first cross-linking reaction and said second cross- linking reaction are induced by said common activator.
