  • Plastic film with optical effect
    Publication number: 20020081424
    Abstract: The present invention relates to a decorative plastic film for the surface treatment, in particular, of vehicle bodies and building facades. It has a micro- or nano-scale structure, in which micro-or nano-scale particles (4) are introduced in uniform shape, size, and orientation into a transparent polymer substrate (3), so that the optically perceptible effect is produced exclusively or largely by optical effects in the collective arrangement of the particles (4).

  • Polymeric compounds and radiation-sensitive mixture containing them
    Patent number: 4910119
    Abstract: New polymers comprising repeat units represented by the formula ##STR1## where R is a hydrogen or a halogen atom, a cyanide group or an alkyl group,R1, R2 and R3 are identical or different, and each denotes a hydrogen or a halogen atom, an alkyl group, an alkoxy group or an alkoxycarbonyl group,R4 is a hydrogen atom or a divalent radical,A denotes the atoms required for completing a mononuclear or dinuclear aromatic ring system andm is 2 or 3,are used as binders in positive-working, radiation-sensitive recording materials.

    Inventors: Arnold Schneller, Juergen Sander
  • Monoacrylates of trihydric phenols and method for producing same
    Patent number: 4739097
    Abstract: Compounds of the general formula I ##STR1## in which R is a hydrogen or halogen atom, a cyanide or an alkyl group having 1-4 carbon atoms andR.sub.1 is a hydrogen or halogen atom, nitro, alkyl, alkoxy, aryl, aryloxy, acyl or alkoxycarbonyl group,are prepared by esterifying two adjacent OH groups to give the cyclic carbonate, esterifying the free OH group with (meth)acrylic acid and selectively hydrolyzing the carbonate. The compounds are free of polyunsaturated impurities and can be used for preparing purely linear polymers.
