Patent ID: 7741013

Claim:
A process for forming a pattern having electrically functional properties on a substrate comprising the steps of: (a) providing a photosensitive layer having a tacky surface disposed on a substrate; (b) providing a transfer sheet comprising a removable support and at least one layer of a thick film composition disposed on the support; (c) image-wise exposing the photosensitive tacky surface to form an imaged layer having unexposed tacky and exposed non-tacky areas; (d) applying the thick film composition of the transfer sheet onto the imaged layer; (e) separating the transfer sheet from the substrate wherein the thick film composition substantially remains on the support in the exposed non-tacky areas of the imaged layer and substantially adheres to the unexposed tacky areas to form a patterned thick film composition; and (f) subjecting the patterned thick film composition to heat thereby forming a patterned article.
