    Abstract: Laminates are produced by bonding substrates of large area with an aqueous adhesive dispersion of a polymer of 5-95 wt.% 4C alkyl acrylate, 5-95 wt.% 1 or 2C alkyl acrylate and optionally other monomer(s). The other monomers are 0-50 wt.% primary monomers, selected from 1-2C alkyl methacrylate, 4C alkyl methacrylates, 3 and 5-16C alkyl (meth)acrylates, vinyl aromatics and ester esters of carboxylic acids containing ≤ 20C; 0-20 wt.% secondary monomers, selected from ethylenically unsaturated acids, anhydrides, nitriles, amides and hydroxyl compounds; and 0-20 wt.% other monomers. An Independent claim is also included for (a) the production of the laminates by bonding with this adhesive.

    Abstract: Adhesives containing, as binder, an aqueous dispersion of a polymer derived from radically polymerizable compounds in which 0.1-20 wt.% of the monomer mixture consists of ethylenically unsaturated acids with at least 20 mol% of the acid groups in the form of salts of at least divalent metals. Independent claims are also included for: (a) A process for the production of laminates from large-surface substrates, in which an adhesive as above is applied to at least one of the surfaces and the substrates are then bonded together after removing water; (b) laminates obtained by this process.

    Abstract: 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.

    Abstract: A method for removing a polymer binder containing carboxylate groups cross-linked via alkaline earth metal ions from impregnated nonwovens comprises: (1) the nonwoven is treated with an aqueous alkali salt solution so that the alkali salt anions combine with the alkaline earth metal cations to form a poorly soluble salt or chelate; and (2) the binder-free fibres are separated. Preferably a phase transfer catalyst, preferably an alkyl phenol ethoxylate, fatty alcohol ethoxylate, oxo alcohol ethoxylate or quat. organic ammonium salt, is used in the alkali salt solution. Calcium ions are the cations present. The binder comprises a radical-polymerised polymer containing 0.1-30 wt.% carboxylate groups, of which 50-100 wt.% are present as salts containing alkaline earth metal cations. The alkali salt solution has a temperature of 10-100 degrees C. The nonwoven is added to the alkali salt solution, which is then optionally stirred before separating the fibres 1-60 minutes later.
