Low surface energy photoresist composition and process
View Patent ↗A fluoropolymer-photoresist composition containing fluorinated polymer for containment of liquid inks in the printing of electronic devices. Methods of applying and treating the fluoropolymer-photoresist composition containing fluorinated polymer to provide low surface energy before and after processing and development of the photoresist.
1. A water-free liquid composition comprising:
a photopolymer material;
a fluorinated polymer, wherein the fluorinated polymer is selected from: fluorinated acid polymers, or fluorinated acid-salt polymers, or combinations thereof, and wherein the fluorinated acid polymer is a rapidly dried fluorinated acid polymer; and
an organic liquid; wherein the weight amount of the photopolymer material is greater than 40% of the combined weight of the photopolymer material and the fluorinated polymer in the composition.
2. The liquid composition of claim 1 wherein the organic liquid is selected from: alcohols, or ethers, or ketones, or lactones, or alcohol-ethers, or acetates, or aldehydes, or esters, or amides, or combinations thereof.
3. The liquid composition of claim 1 wherein the rapid drying process is a freeze drying process.
