Abstract
Official abstract text for this publication.
Disclosed is a water and oil resistant agent comprising a fluorine-containing copolymer obtained by copolymerizing a (meth)acrylate monomer having a polyfluoroalkyl group having 1 to 6 carbon atoms, the agent being able to afford a superior water and oil resistance to a paper. The invention also discloses a composition comprising the water and oil resistant agent, a process for treating a paper thereby and a treated paper thereby.
First claim
Opening claim text (preview).
The invention claimed is: 1. A water and oil resistant agent for paper comprising a fluorine-containing copolymer comprising, as essential components, the repeating units derived from: (a) a fluorine-containing monomer having a fluoroalkyl group represented by the general formula: CH 2 ═C(—X)—C(═O)—Y—Z—Rf (1) wherein X represents a hydrogen atom, a linear or branched C 1 to C 21 alkyl group, a fluorine atom, a chlorine atom, a bromine atom, an iodine atom, a CFX 1 X 2…
