    Abstract: Radiation-curable contact adhesives (I) contain (A) 10-98 wt. % oligomeric or polymeric reaction prod. with mol. wt. 500-100,000 and (B) 2-99 wt. % mono-vinyl cpd. (A) is the reaction prod. of (a) di-isocyanate, (b) 20-99 equiv. % polyester-polyol and/or polyether-polyol (c) 0-79 equiv. % 2-50C diol, (d) an OH gp. which is not directly linked with (II) and (e) a cpd. with an OH or amino gp. namely up to 20C acetal or ketal and/or a cycloaliphatic ether with a 3- or 10-membered ring, amt. of (d+e) is 1-50 equiv. % w.r.t. NCO gps. in (a), equiv. ratio (d):(e) = (10:90)-(90:10), and NCO gps. in (a) are equiv. to the sum of the OH and amino gps. in (b), (c), (d) and (e). Amts. are 40-70 wt. % (A) and 30-60 wt. % (B) and (A) has mol. wt. 1000-40,000 and is derived from (a) 50-98 equiv. % (b) 0-40 equiv. % (c) and 2-40 equiv. % (d+e) (wtih equiv. ratio (d):(e) = (15:85)-(30:70)), (d) is hydroxy(1-20C alkyl)-(meth)acryalte or -(meth)acrylamide, pref. a versatic acid mono-ester (III) of 2,3-dihydroxypropyl 1-(meth)acrylate and/or 1,3-dihydroxypropyl 2-(meth)acrylate, (e) is an up to 20C acetal or ketal with an OH amino gp. or a 3-10membered cycloaliphatic ether with an OH or amino gp. (B) is a vinyl monomer which gives a homopolymer with Tg below 20 deg.C pref. a reaction prod. of the above versatic acid mono-esters with an equimol. amt. of a satd. or mono-unsatd. 4-5C cyclic dicarboxylic anhydride. USE/ADVANTAGE - (I) are useful for the prodn. of labels, adhesives strips, decorative film, etc. These adhesives have a balanced combination of surface tackiness, peel strength and cohesion.

    Abstract: The UV-curable compositions are based on a binder preparation comprising (1) from 99.0 to 20% by weight of a copolymer, (2) from 1.0 to 80% by weight of monoolefinically unsaturated compounds and (3) from 0.0 to 20% by weight of olefinically polyunsaturated compounds and are characterised in that the copolymer (1) is obtainable by subjecting a mixture of (A) from 80 to 99.9% by weight of olefinically unsaturated monomers, (B) from 0 to 10% by weight of a copolymerisable olefinically unsaturated photoinitiator, and (C) from 0 to 10% by weight of a polymerisation-regulating photoinitiator to free-radical polymerisation, where the sum of (B) and (C) is at least 0.1% by weight and the stated percentages by weight are based on the sum of the weights of (A) + (B) + (C).

    Abstract: The invention relates to radiation-reactive mixtures of certain precursors and carbonyl compounds which contain aromatic radicals and, in the UV-excited state, are capable of hydrogen abstraction, which mixtures experience a solubility differentiation on irradiation with actinic light and are suitable for the preparation of polyimides, polyisoindoloquinazolinediones, polyoxazinediones, polyquinazolinediones or polyquinazolones. … They are suitable for the production of insulating layers and printed circuit boards.
