Water insoluble cationic copolymers based on acrylamide and a cationic monomer of general formula (I) in which R and R₁, identical or different, represent a hydrogen atom or a methyl group, X represents an oxygen atom or an NH radical and n represents 2 or 3, containing in molar proportions from 5 to 30% of units cationic and crosslinked with from 0.01% to 0.4% in molar proportions relative to the preceding monomers of bisacrylamidoacetic acid and with approximately from 0.01% to 0.1% in molar proportions relative to the monomers of bisacrylamidoacetic acid , self-reversible dispersions containing them and application in coating in stationery. |
