  • Patent number: 5384378
    Abstract: Copolymers with non-linear optical properties, which contain or are composed of repeating units of the formula (I) ##STR1## where D is an electron donor,A is an electron acceptor,R.sup.1, R.sup.2, R.sup.3 and R.sup.4 can be the same as or different from one another, and are each H, alkyl, cycloalkyl, or R.sup.3 and R.sup.4 are each CN, NO.sub.2 or CHO, or R.sup.1 forms with R.sup.2, or R.sub.3 forms with R.sup.4, a fused-on ring,X is CH and/or N,m is an integer from 2 to 11, andR is hydrogen or methyl,and repeating units of at least one of the formulae (II), (III) and (IV) ##STR2## are suitable for the production of optical components.

  • Patent number: 5011627
    Abstract: Membrane keyboards are manufactured using screen-printable, electrically conductive pastes consisting of 40 to 75% by weight of metal powder (silver, aluminum, copper and their mixtures), 5 to 55% by weight of an organic solvent and 5-20% by weight of and synthetic resin based on a thermoplastic epoxy or phenoxy resin with an average molecular weight of 10,000 to 250,000 and an epoxide content of 0 to 1.
