    Abstract: The invention relates to positive-working, radiation-sensitive mixtures essentially comprising (a1) an organic binder containing acid-labile groups which is insoluble in water, but becomes soluble in aqueous alkaline solutions on treatment with acid, or (a2.1) a polymeric binder which is insoluble in water, but soluble in aqueous alkaline solutions and (a2.2) an organic compound whose solubility in an aqueous alkaline developer is increased by treatment with acid, and (b) an organic compound which produces an acid on exposure to actinic radiation and which additionally contain (c) a strongly basic, organic compound containing hydroxyl, alkoxy or phenoxy anions. These mixtures are suitable for the production of relief structures of improved contrast.

    Abstract: Positive-working radiation-sensitive mixt. is based on (a) polymer(s) contg. acid-labile gps., which are insol. in water and rendered soluble in aq. alkaline soln. by acid; (b) organic photo-acid(s); and (c) other organic cpd(s)., in which (a) comprises 35-70 mole-% 4-hydroxystyrene units (I), 30-50 mole-% 4-tetrahydropyran-2-yloxystyrene units (II) and 0-15 mole-% 4-vinylcyclohexanol units (III); (b) is 2-methyl-4-hydroxy-5-isopropyl-phenyl-dimethylsulphonium triflate (IV); and (c) is an organic ammonium deriv. (V) of (IV) or an analogue. In the formulae, R', R", R'" = 1-4 C alkyl; or R', R" = CH2 gps. linked to a 5-membered ring.

    Abstract: The novel compounds of the general formula I having nonlinear optical properties in which the variables have the following meaning: X is a straight-chain or branched alkanediyl radical having 1 to 20 C atoms or X is a straight-chain or branched alkanediyl radical having 2 to 20 C atoms, the carbon chain of which is interrupted by -O-, -S- and/or -NR-; R is a hydrogen atom, a straight-chain or branched alkyl radical having 1 to 6 C atoms or a cycloalkyl radical, Y is a non-centrosymmetrical radical containing an easily polarisable conjugated pi -electron system and at least one terminal electron acceptor group; are outstandingly suitable as nonlinear optical materials for nonlinear optical arrangements and for the preparation of polymers having nonlinear optical properties. In particular, they are used for the preparation of organopolysiloxanes having nonlinear optical properties and which contain side groups of the general formula Ia in which the variables have the abovementioned meaning. These novel organopolysiloxanes having nonlinear optical properties are in turn outstandingly suitable for the preparation of Langmuir-Blodgett films.
