C) 65 Teile des Aminoplastes A): werden in 35 Teilen des Polyesters B) gelöst. Das gemäß C): nun lösungsmittelfrei in Weichmachungsmittel gelöste Aminoplast wird jetzt in an sich bekannter Weise mit oder ohne Zusatz von Härtungsmittein, z. B. p.#Toluolsulfosäure,. einer nachfolgenden Temperaturbehandlung -in der Schmelze, in der Form, auf beheizten Walzen oder in der Folienherstellung üblichen beheizbaren Bändern, in Eztrudern (bedingt durch die Temperatursteigerung verursachend, Scherwrkung) oder in sonst üblicher Weise unterworfen, bis - _ der Schmelzpure ca. 9000 beträgt, worauf die W4iterkondensation durch geeignete Maßnahmen, z. B. Abkühlen durch gas- förmige tiefgekühlte Luft, unterbrochen wird und sofort zu Pulver vermahlen wird. Das Pulver mit einer Korngröße bis zu max. 100 my wird elektrostatisch mit 60 KV auf einer üblichen Anlage oder mittels Handspritzpistolen auf Stahlblech aufge-tragen und 20 min. bei ZZ 16000 eingebrannt. Es resultieren außergewöhnlich hartelastische hackfilve mit einer Schichtdicke. von ca. 80 my. Beispiel 2: 7 Teile eines Kondensationsproduktes bzw. Alkydharzets bzw. Polyesters aus 2 Mol Aethylenglycol, 1 Mol Terephthalsäure, 1 Mol Benzol-tricarbonsäure- (1,2,4)-an.hydrid, 0,4 Mol 4,4-Diamino-diphenylmethan und 0,8 Mol Tris-hydroxy-äthylisocyanurat, Schmelzpunkt 1100C, werden in der Wärme mit einer Pigmentpaste aus gleichen Teilen Titandioxid und des Aminoplastes aus Beispiel 1 oder Hexamethoxymethylmelamin vermischt, sodaß auf 7, Teile des Alkydharzes 3 Teile der Pigmentpaste zum Einsatz gelangen und diese Mischung wird und anschließend zu Pulver vermahlen. Die Anwendung ist analog Beispiel 1, wobei die besten Ergebnisse bei Verwendung des Aminoplastes aus Beispiel 1 erhalten werden.A) Aminoplast with an acid number of 58, consisting of the reaction product of a Kol ethylene glycol. 0.2 moles of adipic acid, one col trimellitic anhydride and two moles of hexamethoxymethylmelamine. B) Hydroxyl group-containing polyester based on glycerol, 1,2-propylene glycol, phthalic anhydride, adipic acid, acid number 12, hydroxyl number 520, viscosity 75 sec./20 oCDIN 4mm, 75% in ethanol. C) 65 parts of the aminoplast A): are dissolved in 35 parts of the polyester B). According to C): the aminoplast, now dissolved in a plasticizer without a solvent, is now used in a manner known per se with or without the addition of hardeners, e.g. B. p. # Toluenesulfonic acid ,. Subsequent temperature treatment - in the melt, in the mold, on heated rollers or heatable belts customary in film production, in extruders (caused by the increase in temperature , shear force) or in any other customary manner , until the melt track is approx. 9000 , whereupon the W4iterkondensation by suitable measures, z. B. Cooling by gaseous deep-frozen air, is interrupted and is immediately ground to powder. The powder with a grain size of up to a maximum of 100 my is applied electrostatically at 60 KV on a conventional system or using a hand spray gun on sheet steel and baked for 20 minutes at ZZ 16000 . The result is extraordinarily hard-elastic hackfilve with a layer thickness. of about 80 my. Example 2: 7 parts of a condensation product or alkyd resin set or polyester from 2 mol of ethylene glycol, 1 mol of terephthalic acid, 1 mol of benzene-tricarboxylic acid (1,2,4) anhydride, 0.4 mol of 4,4-diamino diphenylmethane and 0.8 mol of tris-hydroxy-ethyl isocyanurate, melting point 1100C mixed in the heat with a pigment paste made from equal parts of titanium dioxide and the aminoplast from Example 1 or hexamethoxymethylmelamine, so that for 7 parts of the alkyd resin 3 parts of the pigment paste are used and this mixture is used and then ground to powder. The application is analogous to Example 1, the best results being obtained using the aminoplast from Example 1.
