    Abstract: 1292499 Adhesive coatings BADISCHE ANILIN- & SODA-FABRIK AG 5 March 1970 [6 March 1969] 10572/70 Heading B2E Pressure-sensitive adhesive coated articles have at least one adhesive coating containing a copolymer of (a) from 50 to 90% by weight of acrylic and/or methacrylic esters of primary and/or secondary alkanols of 4 to 12 carbon atoms, of which at least 25% are derived from alkanols having 6 to 12 carbon atoms, (b) from 10 to 40% by weight of acrylic and/or methacrylic esters of tertiary alcohols of 4 to 12 carbon' atoms and (c) from 3 to 12% by weight of polymerizable heterocyclic N-vinyl compounds and/or other olefin comonomers containing reactive groups. Suitable primary and secondary alkanols for the esters are nbutanol, s-butanol, n-hexanol, n-octanol, 2- ethylhexanol-1 alcohol, n-decanol and n-dodecanol. Suitable tertiary alkanols are t-butanol, 2-ethylhexanol-2 or 2-ethyl decyl alcohol. Suitable N-vinyl compounds are N-vinyl caprolactam, N-vinyl imidazole and N-vinyl 1 pyrrolidone. Other suitable comonomers are acrylic acid, methacrylic acid, acrylomide, methacrylomide, N - methylacrylomide, N - methylol acrylomide, N - methalol methacrylomide, N - methoxy methacrylomide, N - n - butoxy methacrylomide, maleic acid, itaconic acid and fumaric acid and their amides, and crotonic acid and its amide. Other suitable monomers, containing hydroxyl groups are specified. The substrate may be sodium paper, metal foils, such as of aluminium, films of polyethylene, polyvinyl chloride, polystyrene and polyethylene terephthalate, foamed materials such as of rubber, polyvinyl chloride, polystyrene, polyurethane and polyether and woven and non-woven webs of fibrous material such as woven textile fabrics and non-woven fabrics of natural and/or synthetic fibres.

    Abstract: 1316590 Unsaturated sulphito-betaines BADISCHE ANILIN- & SODA-FABRIK AG 18 Sept 1970 [20 Sept 1969] 44628/70 Heading C2C [Also in Division C3] The invention comprises olefinically unsaturated sulphito-betaines, particularly those having the formula where X is -O- or -NH-, R 1 is an optionally substituted vinyl group, R 2 and R 3 each represent an alkyl group or together with the linking N atom form a heterocyclic ring which optionally contains at least one further hetero atom, R 4 is H, a phenyl radical, a carbamoyl radical, or an alkyl or alkenyl radical having up to 4 C atoms and optionally substituted by a halogen atom, an amido group, an epoxy group or a phenyl radical, and n is an integer from 1 to 18. The moiety R 1 -COX- is preferably an acyloxy or acylamino radical derived from an olefinically unsaturated monocarboxylic acid or dicarboxylic acid having 3-5 carbon atoms (e.g. acrylic, methacrylic, maleic, fumaric or itaconic acid). The sulphitobetaines can be prepared by reacting (a) equimolar amounts of sulphur dioxide and an alkylene oxide with (b) an olefinically unsaturated tertiary amine.
