Hydrogel, which can be photostructured in contact exposure and which has linker groups

摘要

A photostructurable liquid composition is for producing a hydrogel layer based on polyacrylamide. The composition, in addition to containing the monomer precursor of the polyacrylamide, the cross-linking agent and the photoinitiator, contains at least one film former, at least one comonomer having reactive linker groups, and at least one softener.
