LEVELLING AGENT AND ANTI-CRATERING AGENT

摘要

Use of a polymer as a levelling agent or anti−cratering agent, said polymer comprising at least one fluorinated unit represented by formula l,(Formula 1) wherein R?1¿ is a moiety represented by C¿n?F¿2n+l?−(CH¿2&que st;)¿m?−, AC¿n?F¿2n?−(CH¿2?&rp ar;¿m?−, C¿n?F¿2n+l?−(CH¿2&que st;)¿m?−(OCH¿2?CHR?5&i quest;)¿p?−, AC¿n?F¿2n?−(CH¿2?&rp ar;¿m?−(OCH¿2?CHR?5¿ )¿p'? C¿n?F¿2n+1?−(CH¿2&que st;)¿m?−X−, AC¿n?F¿2n?−(CH¿2?&rp ar;¿m?−X− AC¿n?F¿2n?−(CH¿2?&rp ar;¿m?−(OCH¿2?CHR?5¿ )¿p?−X or C¿n?F¿2n+l?−(CH¿2&que st;)¿m?−(OCH¿2?CHR?5&i quest;)¿p?−X−; wherein A = H, Cl, Br, I, a C¿l−12? alkyl or a OC¿1−12 ?alkyl, wherein 4 ≤ n ≤ 20,0 ≤ m ∼≤ 4 and 0 ≤ p ≤ 20, wherein X is a spacer moiety selected from the group consisting of esters, amides, sulphoamides, mercapto groups, polyurethane groups and alkyl groups, wherein R?2¿ is H, a metal moiety, an (alkyl)ammonium moiety or an alkyl group, C¿n?F¿2n+l?−(CH¿2&que st;)¿m?−, AC¿n?F¿2n?−(CH¿2?&rp ar;¿m?−, C¿n?F¿2n+1?−(CH¿2&que st;)¿m?−(OCH¿2?CHR?5&i quest;)¿p?−, AC¿n?F¿2n?−(CH¿2?&rp ar;¿m?−(OCH¿2?CHR?5¿ )¿p'?
