Reusable protective film or label, coated with adhesive containing copolymer including ureido- or thioureido-substituted monomer units as binder, allowing easy removal without leaving residues

摘要

Adhesive-coated, reusable protective film or reusable label, where the adhesive comprises a radical polymerizable copolymer (A) containing 0.1-10 wt.% (based on (A)) of units derived from a compound (I) having copolymerizable ethylenically unsaturated group(s) and an optionally substituted ureido or thioureido group. An adhesive-coated, reusable protective film or reusable label is claimed, where the adhesive comprises a radical polymerizable copolymer (A) containing 0.1-10 wt. % (based on (A)) of units derived from a compound (I) having at least one copolymerizable ethylenically unsaturated group and a (thio)ureido group of formula -NR1-C(X)-NHR2. R1, R2H or 1-5C alkyl; or R1 + R22-4C alkylene bridge, optionally substituted by 1 or 2 of 1-4C alkoxy or OH; and X : O or S. An independent claim is included for the use of (A) as a binder in adhesives for reusable protective films or labels.
