    Abstract: Radiation-curable tacky adhesive contains oligomeric or polymeric reaction prods. (I), with mol.wt. 500-100000, and 2-90 wt.% monovinyl cpds. (I) are reaction prods. of (a) diisocyanates, (b) 20-99 equiv. % w.r.t. (a), of polyester-ols and/or polyether-ols, (c) 0-60 equiv. -% 2-50C diols and a total of 1-50 equiv.-% of (d) 2-20C-hydroxyalkyl (meth)acrylate and (e) monohydroxyalkylcarboxylic acids in 1:9 to 9:1 equiv. ratio. The adhesive pref. contains 40-70 wt.% (I) of mol.wt. 1000-30000 obtd. from 50-98 equiv.-% (b), 0-40 equiv.-% (c) and 2-40 equiv.-% (d) + (e) in 3:7 to 7:3 equiv. ratio. (II) is a (substd.) 1-20C alkanol (meth)acrylate ester.

    Abstract: Radiation-curable contact adhesives containing (A) oligomeric or polymeric reaction products of (a) diisocyanates, (b) polyesterols and/or polyetherols, (c) optionally C2-C50-diols, (d) C2-C20-hydroxyalkyl (meth)acrylates and (e) monohydroxyalkylcarboxylic acids in defined weight proportions and (e) monovinyl compounds in an amount of 2-90% by weight, based on A+B, produce contact adhesive layers of particularly high surface tackiness and particularly high cohesion.

    Abstract: Synthetic resins are obtainable by chemically bonding one or more compounds of the general formula I (* CHEMICAL STRUCTURE *) (I) where R1 is -OH, -NH2, (* CHEMICAL STRUCTURE *) -NHR3 or (* CHEMICAL STRUCTURE *) R2 is -H, -CH3 or -C2H5, R3 is -CmH2m+1, where m is from 1 to 6, R4 is -H or -CH3 and n is from 1 to 12, via the oxygen or nitrogen atom of R1 to one or more polymers A which consist of a) from 50 to 100% by weight of one or more esters of acrylic or methacrylic acid with monohydric alcohols of 1 to 18 carbon atoms or a mixture of these esters (monomers a) and b) from 0 to 50% by weight of other copolymerizable monomers (monomers b) in polymerized form, in amounts such that the synthetic resin contains from 0.01 to 1 mole of double bonds per kg of polymer A. After exposure to ultraviolet light or to electrons, these synthetic resins are suitable as contact adhesives.
