    Abstract: Novel polymers contain phthalocyanine ring systems bonded via axial bonds to a central metal atom in the polymer chain and consist of repeating units of the general formula (I) (I) In the general formula (I), Pcs is a phthalocyanine ring system having peripheral substituents, Me is the central atom of the phthalocyanine ring system, which atom is bonded in the polymer main chain, suitable central metal atoms Me being silicon and germanium, R is alkylene, R' and R'' are each alkyl, cycloalkyl, aryl or alkoxy and Z is a silicon-carbon bond or further Si-containing groups. The novel polymers can be particularly advantageously used for the production of ultrathin layers by the LB technique, optically transparent films having high optical anisotropy and a high volume concentration of phthalocyanine radicals being formed.

    Abstract: In the production of resist patterns by applying a photosensitive, positive-working resist layer based on photodegradable polymers to a substrate, image-wise exposing the resist layer to actinic light and removing the exposed layer portions to develop the resist pattern, a photosensitive resist layer is used which is made of a poly(diacetylene) which is, in particular, soluble. The invention also relates to dry film resists with a temporary, dimensionally stable layer base, a photosensitive photodegradable resist layer applied thereto and based on poly(diacetylenes), which are preferably soluble, and, optionally, a top layer on the photosensitive resist layer.

    Abstract: Multi-layered, highly radiation-sensitive recording material, which can be fixed easily, consists of (A) a dimensionally stable sheet support; (B) opt. a subbing coat; (C) a layer of a suspension of radiation-sensitive diyne crystals (I) in a polymeric binder (II), in which (I) can be dissolved by treating the material with a solvent a and/or by increasing the temp., and (D) a transparent top coat (III), which is scarcely water-soluble. Rapid and simple fixing is possible after exposure. (I) is a bisurethane of formula (R-NH-CO-O-Y-X-C=C)2 (where X is (CH2)n with n = 1-9; Y can be absent or -(O-CHR'-CHR")m with m = 1-3 and R'=H, R" = Me or R'=Me, R" = H, R is H, aryl, aralkyl, alkyl, alkenyl, chloralkyl or alkoxyalkyl with 1-17C), (II) a vinylpyrrolidone polymer, and (III) an alcohol-soluble, synthetic polyamide.
