    Abstract: The invention relates to a method for producing coatings, adhesive layers or sealing systems for primed or unprimed substrates. The inventive method comprises the following steps: applying to and/or introducing into the substrate (1) coating substances, adhesive substances and/or sealing compounds that contain a component (A) which comprises in the statistical average at least one group (a) with at least one bond per molecule that can be activated by actinic radiation in the form of (1.1) a water-free and solvent-free liquid or melt, (1.2) a powder, (1.3) a dispersion or a solution in at least one organic solvent, or (1.4) in an aqueous medium, (2) drying the layer from a dispersion or solution (1.3) or (1.4) or allowing the resulting layer of the melt (1.1) to solidify or maintaining it in the molten state by heating, (3) melting the solid layer (1.2), (1.3) or (1.4) by heating, and (4) curing the liquid layer resulting from process step (1) or the molten layer resulting from process step (2) or (3) in the molten state, during solidification and/or after solidification with radiation in the near infrared range.

    Abstract: New mixtures (F i) of at least two (preferably 2-4) compounds (I), each having at least two double bonds and where at least two of (I) have at least two (meth)acrylate ester groups as double bond components, have a weight-functionality ratio (WFR) value (defined as the sum of the (molar fraction times molecular weight divided by number of double bonds) values for all the components (I)) of 200-600 (preferably 250-350) g per mole double bond. Independent claims are included for: (a) the preparation of (F i); (b) the production of a crosslinked hydrogel (CHG), by polymerizing the mixture (F i) with (meth)acrylic acid, optionally other monoethylenically unsaturated monomers (N) and optionally further copolymerizable hydrophilic comonomer(s) (M) in presence of radical initiator(s) (K) and optionally graft substrate(s) (L), then optionally post-crosslinking, drying and optionally milling and/or screening; (c) polymers obtained by the above CHG production method; (d) CHG's, containing at least one M in polymerized form and crosslinked with (F i); (e) mixtures comprising (by weight) 0.1-40% (F i) and (meth0acrylic acid, 0.5-99.9% (M), 0-10% esterification catalyst(s) (C), 0-5% polymerization inhibitor(s) (D), 0-10% solvent (E) and optionally diluents (G) to 100%; (f) CHG's obtained from the mixtures, followed by optionally post-crosslinking, drying and optionally milling and/or screening.

    Abstract: Trimethylolpropane esters are new. Trimethylolpropane esters are of formula (1). (1) AO : OCH2CH2, OCH2CH(CH3), OCH(CH3)CH2, n1-n3 : 4-6; n1+n2+n3+n4 : 14-16; m1-m3 : 1-3; m1+m2+m3 : 4-6; R1-R3 : 4-6 Independent claims are included for: (1) a process for the production of esters of formula (1) by reaction of alkoxylated trimethylolpropane with (meth)acrylic acid in the presence of at least one esterification catalyst (C) and at least one polymerization inhibitor (D) as well as optionally a solvent (E) that forms an azeotrope with water; optionally removal of at least a portion of the water from the reaction mixture during or after the water from the reaction, optiionally neutralizing the reaction mixture; optionally removing the solvent if present by distillation and/or stripping with an inert gas; (2) across-linked hydrogel prepared by polymerization of an ester of formula (1) with (meth)acrylic acid with optionally additional monoethylenicaly unsaturated compounds (N) as well as optionally at least a further copolymerizable hydrophilic monomer (M) in the presence of at least one radicatl initiator (K) and optionally a graft base (L); optionally cross-linking of the resulting reaction mixture; drying of the reaction mixture and optionally grinding the reaction mixture; (3) a mixture comprising 0.1-40 wt.% of a ester of formula (1) and (meth)acrylic acid, 0.5-99.9 wt.% of a hydrophilic monomer (M), 0-10 wt.% of an esterification catalyst (C), 0-5 wt.% polymerization inhibitor (D) and 0-10 wt.% sovlent (E).
