Abstract: Application of coatings or double layers onto supports comprises curing a coating compsn. contg. polymerisable binders and photo-inductors, by the action of light of wave length 200-500 nm. The coating compsn. consists of (A) 99.9-20% of a reaction prod. from (a) opt. (partially)etherified amine-HCHO condensates, and (b) acrylic and/or methacrylic cpds. contg. OH or NH2 gps, in amts. of 1/3-1 mol. acrylic cpds/equiv. CH2-O-gps. in the amine-HCHO condensate; (B) 0-60% of copolymerisable organic cpds. liq. at room temp; (c) 0-80% of pigments or fillers; (D) 0-20% of organic auxiliary prods. usual in paints and varnishes; (E) 0-50% of other unsatd. polymerisable binders; and (F) 0.1-20% of a photo-inductor system. The binders are cheap, easily prepd. and are rapidly cured. The compsns. may be applied to wood, metal, paper or synthetic resins and may also be used as mastics or printing inks.

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.

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: Finely divided waxes of mol. wt. 500-10000 and particle size 2-12 mu m are prepd. from a wax melt. The wax should have a melt viscosity of 100-400 mPas and an electric resistance 103-1010 ohm. The melt is split into fine particles by application of a potential of 50-200kV. The waxes can be used as matting agents for paints. Most waxes cannot be reduced to a small enough particle size by simple grinding and a narrow range of sizes is also essential for this application. Suitable prods. can be obtd. by pptn. from soln. by addn. of a non-solvent but this involves the handling of inflammab le liqs. and expensive drying processes. Air-spraying of wax solns. gives a very wide range of particle sizes. Atomisation with application of an electric potential enables a fully satisfactory prod. to be obtd.
