Description
als durch UV-Licht aktivierbare Härtungskatalysatoren für säurehärtende Harze und Harzgemische.as curing catalysts for acid-curing resins and resin mixtures that can be activated by UV light.
2525th
Es ist bekannt, durch Säuren härtbaren Harzen oder Harzgemischen halogenhaltige organische Verbindungen, z. B. Bromoform, Jodoform, Tetrabromkohlenstoff, Hexabromäthan, Bromal, Z5-Dimethyl-(a-tribrornacetophenon und 9,10-Dibromanthracen, zuzusetzen. Bei Bestrahlung solcher Gemische mit UV-Licht werden aus diesen Zusätzen Säuren freigesetzt, die ihrerseits dann die Härtung der Harze bzw. Harzgemische herbeiführen. Solche Zubereitungen sind schon z. B. in der Reproduktionstechnik verwendet worden (NL-OS 65 12 894).It is known to use acid-curable resins or resin mixtures to produce halogen-containing organic compounds, z. B. bromoform, iodoform, carbon tetrabromide, hexabromoethane, bromal, Z5-dimethyl- (a-tribrornoacetophenone and 9,10-dibromoanthracene to be added. at If such mixtures are irradiated with UV light, acids are released from these additives, which in turn then bring about the hardening of the resins or resin mixtures. Such preparations are already z. Am reproductive technology has been used (NL-OS 65 12 894).
Die meisten niedermolekularen Halogenverbindungen sind jedoch flüchtig, haben einen durchdringenden Geruch und reizen die Schleimhäute. Manche sind auch thermisch nicht völlig stabil, so daß die mit ihnen versetzten Zubereitungen nicht lange lagerfähig sind.Most of the low molecular weight halogen compounds, however, are volatile, have a penetrating effect Odor and irritate the mucous membranes. Some are also not completely thermally stable, so that with them mixed preparations cannot be stored for a long time.
Gegenstand der Erfindung ist die Verwendung von Benzophenonderivaten der FormelThe invention relates to the use of benzophenone derivatives of the formula

als durch UV-Licht aktivierbare Härtungskatalysatoren für säurehärtende Harze und Harzgemische.as curing catalysts for acid-curing resins and resin mixtures that can be activated by UV light.
Diese Verbindungen haben die genannten Nachteile nicht. Gegenüber den bisher bekannten lichtempfindlichen Säurekatalysatoren zeichnen sie sich im allgemeinen zudem durch eine höhere Empfindlichkeit gegenüber UV-Licht und damit auch höhere Reaktivität aus. Andererseits ist ihre Stabilität derart, daß sie in Mischung mit den betreffenden Harzen bei Raumtemperatur, aber auch bei leicht erhöhter Temperatur, beliebig lagerfähig sind.These connections do not have the disadvantages mentioned. Compared to the previously known photosensitive They are also generally more sensitive to acid catalysts UV light and thus higher reactivity. On the other hand, their stability is such that they can be used in Mixing with the resins in question at room temperature, but also at a slightly elevated temperature, can be stored as required.

Auch Gemische dieser Verbindungen können verwendet werden.Mixtures of these compounds can also be used.
Geeignete Harze, die mit den erfindungsgemäßen Katalysatoren durch Lichteinwirkung gehärtet werden können, sind z.B. Phenolharze und Aminoplaste, insbesondere Harnstoff- und Melaminharze, entweder allein oder in Kombination mit anderen Harzen, wie Nitrocellulose, Alkydharzen und anderen Polyestern. Sie können als Lacke, für Reproduktionszwecke, z. B. als sogenannte Photo-Resistlacke, aber auch zur Beschichtung von Textilien verwendet werden. Die erfindungsgemäßen Verbindungen können ferner zur Säurehärtung von Epoxyharzen sowie zur Aktivierung von Methylolverbindungen, z. B. Methyloläthern von PoIycarbonsäureamiden, wie Polyacryl- und -methacrylsäureamiden und Polymeren, die Carbamidsäureester von N-Methylolamiden enthalten, dienen.Suitable resins which are cured with the catalysts according to the invention by exposure to light are, for example, phenolic resins and aminoplasts, especially urea and melamine resins, either alone or in combination with other resins such as nitrocellulose, alkyd resins and other polyesters. They can be used as varnishes, for reproduction purposes, e.g. B. as so-called photo-resist paints, but also for coating used by textiles. The compounds according to the invention can also be used for acid hardening of epoxy resins and for the activation of methylol compounds, e.g. B. methylol ethers of polycarboxamides, such as polyacrylic and methacrylic acid amides and polymers, the carbamic acid esters of Containing N-methylolamides, serve.
Zweckmäßig werden die beanspruchten Verbindungen den Harzen in Mengen von etwa 0,1 bis etwa 10, vorzugsweise von etwa 1 bis etwa 6 Gewichtsprozent zugesetzt, bezogen auf das härtbare Harz, das unter Umständen in den üblichen Lösungsmitteln gelöst sein kann.The claimed compounds are expediently added to the resins in amounts of about 0.1 to about 10 preferably added from about 1 to about 6 percent by weight, based on the curable resin, which under Can be dissolved in the usual solvents under certain circumstances.
Solche Gemische sind im Dunkeln praktisch unbegrenzt lagerstabil, beim Belichten mit UV-Licht, zu dessen Erzeugung die üblichen Lichtquellen herangezogen werden können, setzt aber die erwünschte Gelierung ein, und die Härtung erfolgt, je nach der Harzzusammensetzung, entweder sofort oder nach der üblichen Einbrennzeit.Such mixtures have practically unlimited storage stability in the dark, when exposed to UV light, too the generation of which the usual light sources can be used, but sets the desired Gelation occurs and curing takes place either immediately or after the resin composition, depending on the resin composition usual burn-in time.
