摘要： A process for the preparation of a synthetic resin dispersion stabilized by a protective colloid employing at least one initiator and based on a polymer of (a) a first monomer of at least one ester of acrylic acid or methacrylic acid and an alcohol containing 1 to 22 carbon atoms; and optionally, (b) a second monomer which can be copolymerized with the first monomers. The process comprises introducing at least 50% of the monomers based on the total weight of the monomers, at least 50% of the protective colloid based on the total weight of the protective colloid, and up to 50% of the initiator based on the total weight of the initiator into a reaction vessel to form an aqueous emulsion. Any remaining monomers and protective colloid and at least 50% of the initiator based on the total weight of the initiator are then added to the reaction vessel at a temperature of 30.degree. to 100.degree.

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： Disclosed is a radiation-sensitive composition, a recording material prepared therewith, and process therefor. The invention is suitable for the production of printing plates and photoresists. The composition contains a 1,2-quinonediazide or a combination of (1) a compound which, under the action of actinic radiation, forms a strong acid, and (2) a compound which possesses at least one acid-cleavable C--O--C bond, the solubility of which in a liquid developer is increased by the action of acid and, as the binder, a polymer having lateral crosslinking groups of the formula --CH.sub.2 OR, in which R is a hydrogen atom, a lower alkyl group, acyl group or hydroxyalkyl group. After being exposed and developed, the composition can be thermally cured and results in an image stencil exhibiting a clean background.
