    摘要: The present invention relates to a photosensitive transfer material, which comprises a flexible temporary support film which is preferably transparent, a thermoplastic photosensitive layer, optionally a flexible cover film on the free side of the photosensitive layer and, optionally, an intermediate layer between the support film and the photosensitive layer. The photosensitive transfer material is suitable for manufacturing photoresist stencils and solder masks. The temporary support film has a rough surface which exerts an embossing effect on the surface of the photosensitive layer and the intermediate layer, respectively. The mat-finish of the intermediate layer prevents an irregular deformation of this layer in moist air, while the mat-finish of the photosensitive layer precludes unwanted reflections.

    摘要: A radiation-sensitive composition is disclosed which comprises: (a) a polymeric binder comprised of an alkenyl phenol monomer; (b) a compound which forms a strong acid under the action of actinic radiation; and (c) a compound which contains at least one acid-cleavable C-O-C bond and has a solubility in a liquid developer which is increased by the action of acid. The composition yields positive-working recording layers which are more flexible than layers comprising known novolak binders.

    摘要: The present invention relates to thermoplastic moulding compositions of (A) 99.5 to 80% by weight, of at least one amorphous linear polyamide and (B) 0.5 to 20% by weight of at least one segmented thermoplastic elastomeric copolyester. These novel moulding compositions combine good toughness and hardness with good elongation and stiffness properties as well as good flowing properties of the molten material.
