PROBLEM TO BE SOLVED: To provide a screen printable hydrogel composition having potential for forming a desired pattern and a method for placement of desired dimensions of the gel directly onto a substrate with little to no yield loss and for precise control over the ultimate thickness. SOLUTION: The invention relates to the screen printable hydrogel composition comprising, (a) a soluble or partially soluble polymer wherein said polymer is a copolymer, interpolymer or mixture thereof, (b) an initiation system, (c) a thickener, (d) water, and (e) a solvent, with the proviso that the composition has viscosity of greater than about 10 Pa×s.
