WATER AND OIL RESISTANT AGENT FOR PAPER, TREATMENT PROCESS AND PAPER

摘要

The present invention is directed to a water and oil resistant agent comprising a fluorine-containing copolymer obtained by copolymerizing a (meth)acrylate monomer having a polyfluoroalkyl group having 1 - 6 carbon atoms, hydrophilic monomer, and monomer having an anion-donating group, which agent affords a superior water and oil resistance to paper. The invention also discloses a process for treating paper with the water and oil resistant agent and a treated paper thereby.
