    Abstract: The present invention relates to partially branched polymers having a number-average molecular weight Mn in the range from 500 to 20 000 daltons and synthesized from ethylenically unsaturated monomers including:i) from 80 to 99.9% by weight of monoethylenically unsaturated monomers A, andii) from 0.1 to 20% by weight of monomers B containing at least two nonconjugated ethylenically unsaturated double bonds,the weight fraction of the monomers A and B being based on the total amount of the ethylenically unsaturated monomers that constitute the polymer.

    Abstract: The invention relates to transparent, undiscolored and uncrosslinked, radiation-curable binders of low additive content, obtainable by polymer-analogous reaction of epoxy-functional (meth)acrylate copolymers (A) with an unsaturated monocarboxylic acid (B), the reaction a) of the copolymer (A) taking place with at least 2 equivalents of the carboxylic acid (B), b) in the absence of reaction accelerators and inhibitors, c) in a continuously operated reactor, d) without solvent, e) at from 130 to 170° C., f) with a degree of conversion of at least 90% within an average residence time which is as short as possible but sufficient, and which is below 13 to 22 minutes. The reaction products contain virtually no byproducts and are advantageous binders for clearcoat materials and powder coating materials.

    Abstract: Positive-working radiation-sensitive mixt. is based on (a) either (a-1) water-insol. organic polymeric binder(s) with acid-labile gps., rendered soluble in aq. alkaline soln. by the action of acid or (a-2.1) a water-insol. polymeric binder, which is soluble in aq. alkaline soln., and (a-2.2) a low mol. organic cpd., which is rendered more soluble in an aq. alkaline developer by the action of an acid; (b) organic photo-acid(s); and opt. (c) organic cpd(s). other than (b). The novelty is that at least one of (a-1), (a-2.1), (a-2.2), (b) and (c) contains a gp. of formula -O N -R4 (I) or (c) is of formula O-CO-Ä(CH2Ün-CH2-N R3 (II); in which R = 1-6 C alkyl; n = 1-6.

    Abstract: The invention relates to a positive radiation-sensitive composition and a process for obtaining relief images. … The radiation-sensitive composition contains… a) a water-insoluble polymeric binder which is soluble or at least dispersible in aqueous alkaline solutions, and… b) an organic compound whose solubility in an aqueous alkaline developer is increased by exposure to acid and which contains at least one acid-cleavable grouping and, in addition, a further grouping which produces a strong acid when exposed to radiation, the polymeric binder (a) consisting of a mixture of a phenolic polymer and a resin of the novolak type. … The mixture according to the invention is suitable, in particular, for producing photoresists.
