    Abstract: The invention relates to a radiation-sensitive mixture and to a process for the formation of relief patterns. The radiation-sensitive mixture contains (a) a polymeric binder which is insoluble in water and soluble in aqueous-alkaline solutions, and (b) an organic compound whose solubility in an aqueous-alkaline developer is increased by the action of acid and which contains at least one grouping cleavable by acid and additionally one grouping which forms a strong acid under the action of radiation, the polymeric binder (a) containing 5 to 35 mol% of copolymerised or co-condensed monomer units having acid-sensitive groupings, or the acid-sensitive groupings having been introduced by a polymer-analogous reaction. It is suitable for the formation of relief patterns.

    Abstract: A radiation-sensitive mixture consists of a polymeric binder which is insoluble in water but soluble in aqueous alkaline solutions, and of an organic compound whose solubility in an aqueous alkaline developer is increased by the action of an acid and which contains both one or more acid-cleavable groups and a group which forms a strong acid under the action of radiation. The radiation-sensitive mixture is suitable for use in photosensitive coating materials for the production of relief patterns and relief images.

    Abstract: Compositions which can be crosslinked under an atmospheric oxygen atmosphere by means of ultraviolet irradiation and are based on (meth)acrylate copolymers having a K value of from 10 to 100, obtained by free-radical polymerisation in solid phase or solution of a) 5 to 97.4% by weight of i-amyl acrylate and/or i-amyl methacrylate and b) 0 to 89.9% by weight of (meth)acrylates whose hompolymers have a glass transition temperature of below -30 DEG C, c) 2.5 to 30% by weight of alpha , beta -monoolefinically unsaturated compounds whose homopolymers have a glass transition temperature of above - 30 DEG C, d) 0 to 10% by weight of monoolefinically unsaturated acids and/or anhydrides thereof, e) 0 to 20% by weight of further olefinically unsaturated monomers containing at least one of the following functional groups: hydroxyl, amide, epoxide, ether, ester, urethane, urea, primary, secondary or tertiary amine and ether, and f) 0.1 to 5% by weight of a copolymerisable benzophenone or acetophenone derivative, the sum of the percentages by weight x = a + b + c + d + f in each case being 100.

    Abstract: The invention relates to compounds containing carbonate groups and carbonyl groups and having the general formula (* CHEMICAL STRUCTURE *) in which R stands for a C1-C4-alkyl radical, an aryl radical, or a radical R1, where R1 has the following formula (* CHEMICAL STRUCTURE *) in which R2 to R6 stand for H, alkyl, OH, O-alkyl, SH, S-alkyl, halogen, N(alkyl)2, or N(alkyl)(aryl) and at least one but not more than three of the radicals R2 to R6 stand for a radical of the formula (* CHEMICAL STRUCTURE *) in which A, B and C stand for alkylene, cycloalkylene, oxaalkylene, polyoxaalkylene or arylene, k and l both stand for an integer from 1 to 80, and the end group Z stands for alkyl, aryl, alkoxycarbonyl, alkoxycarbonyloxy, or aryl. These compounds are suitable for use as emulsifiers for dispersions.
