Patent ID: 8367551

Claim:
A process comprising: a) forcing a deposit composition comprising from 0.1 to 50 percent by weight of at least one of an etchant or modifier, a dispersing vehicle, wherein the dispersing vehicle is at least about 80 weight/volume percent water, and from 0.1 to 8 percent by weight, based on the total weight of the deposit composition, of an ultrahigh molecular weight viscoelastic polymer selected from the group consisting of poly(ethylene oxide), poly(acrylamide),[acrylamide-3-(2-acrylamido-2-methylpropyl)dimethylammonio)-1-propanesulfonate copolymer], and having a molecular weight greater than 1,000,000 dissolved in the dispersing vehicle, the ultrahigh molecular weight polymer and the dispersing vehicle both being chemically stable to the etchant or modifier, through an orifice to form a continuous filament, b) drawing the continuous filament to a draw ratio between 2:1 and 100:1; c) depositing the continuous filament onto a surface layer on a substrate in an image-wise manner; d) allowing the etchant or modifier in the deposited continuous filament to react with the surface layer on the substrate, thereby removing or otherwise modifying the physical properties of the surface layer in the desired image.
