    Abstract: Acylphosphine oxide compounds of the general formula where R1 is alkyl, cyclohexyl, cyclopentyl, aryl which is unsubstituted or substituted by halogen, alkyl or alkoxy, or an S-containing or N-containing five-membered or six-membered heterocyclic radical, R2 has one of the meanings of R1 (but R1 and R2 may be identical or different) or is alkoxy, aryloxy or aralkoxy, or R1 and R2 together form a ring and R3 is an at least disubstituted phenyl, pyridyl, furyl or thienyl radical which carries, at least at the two carbon atoms adjacent to the linkage point of the carbonyl group, the substituents A and B, which may be identical or different, and each of which is alkyl, alkoxy or alkylthio of 1 to 6 carbon atoms, cycloalkyl of 5 to 7 carbon atoms, phenyl or halogen, or R3 is alpha -naphthyl substituted by A and B at least in the 2- and 8-positions or is beta -naphthyl substituted by A and B at least in the 1- and 3-positions, a process for the preparation of these acylphosphine oxide compounds from acid halides of the general formula where X is chlorine or bromine, and a phosphine of the general formula and the use of these acylphosphine oxide compounds as photoinitiators in photopolymerizable surface coatings, finishes and printing inks.

    Abstract: A process for the preparation of soft and hard resins, and their use in surface-coating binders. According to the invention, soft and hard resins are prepared from a urea and a CH-acidic aldehyde by reacting a urea of the general formula (I) (I) where X is oxygen or sulfur and R1 and R2 are hydrogen or identical or different alkyl, aryl or aralkyl, or may be an alkyleneurea radical, with at least 2 moles of a CH-acidic aldehyde of the general formula (II) (II) where R3 is hydrogen and R4 is alkyl, aryl or aralkyl, or R3 and R4 are identical or different alkyl, aryl or aralkyl, in the presence of a strong acid, to give a condensation product, and then treating the latter with a base in an anhydrous medium. These soft and hard resins are used, in combination with other film-forming agents, as surface-coating binders.

    Abstract: A process for the preparation of soft and hard resins, and their use in surface-coating binders are disclosed. According to the invention, soft and hard resins are prepared from a urea, formaldehyde and a CH-acidic aldehyde by reacting a urea of the general formula (I) or (II) (I) (II) where R1 and R2 are hydrogen or identical or different alkyl, A is alkylene and X is oxygen or sulfur, with formaldehyde and a CH-acidic aldehyde of the general formula (III) where R3 and R4 are identical or different alkyl, aryl or alkylaryl wherein the urea, formaldehyde and CH-acidic aldehyde are employed in a mole ratio of from 1:2:2 to 1:4:4, at from 60 DEG to 150 DEG C., in the presence of an acid and in the presence or absence of a solvent and/or diluent, and then treating the product with a base in an anhydrousmedium.
