ABSTRACT:
A method of providing patterned, thin-film materials on flexible substrates by depositing a first, etchable, integral mask onto a substrate, depositing a second pattern material over the mask region and then removing the mask, such as by etching. Patterned films useful as printed circuits and the like can be prepared by this method. In an alternate embodiment, patterned particles can be prepared for dispersion in a vehicle or matrix using the described process.
