    Abstract: Binder for transfer printing comprises a copolymer (IA) of 5-95 (wt.)% N-vinylcaprolactam (II), 95-5% N-vinylpyrrolidone (III) and 0.30% 1-14C alkyl or 2-3C hydroxyalkyl (meth)acrylate, (meth)acrylic, maleic or itaconic acid, in the form of alkali or ammonium salt, and/or (meth)acrylamide; or a copolymer (IB) of 20-80% (II) and 80-20% 1-14C alkyl (meth)acrylate and/or acrylamide. If (I) contains 1-4C alkyl (meth)acrylate, the amt. of this is max. 30%. Pref. (IA) contains 20-80% (II), 80-20% (III) and 0-30% 1-8C alkyl or 2-3C hydroxyalkyl acrylate, vinyl-acetate, or -propionate and/or acrylamide. (IB) contains 30-60% (II) and 70-40% acrylamide. The inks and pastes contain 0.1-30% (I); (0.5-20% (I)) in inks and 1.5-30% (I) in pastes.

    Abstract: Low-molecular-weight polymers of acrylic acid esters are obtainable by subjecting a) from 80 to 100 % by weight of at least one acrylic acid ester of a C1- to C8-alkanol (monomers I) and b) from 0 to 20 % by weight of other copolymerisable monomers (monomers II) to free-radical polymerisation in a pressure vessel at temperatures of from 130 to 140 DEG C in isopropanol solution in such a manner that from 70 to 95 % by weight of a solvent is introduced into the vessel and the remainder of the polymerisation batch is fed in continuously over the course of from 3 to 7 hours in separate feeds, of which one contains the monomers, and, when the polymerisation is complete, the solvent is removed by vacuum distillation, the proportion by weight of the solvent, based on the monomers, being from 5 to 15 %, the proportion by weight of the initiators, based on the monomers, being from 0.5 to 3 %, and the half life period of the initiators at the polymerisation temperature being from 10 seconds to 3 hours. These low-molecular-weight polymers are suitable as external plasticisers in coating compositions based on synthetic resins.
