摘要:
Substituted naphthacenediones of the formula I ##STR1## in which R.sup.1 to R.sup.8 are H and at least one of R.sup.1 to R.sup.8, for example R.sup.2 and R.sup.3 or R.sup.2 and R.sup.6, are, for example, C.sub.1 -C.sub.20 alkoxy, C.sub.1 -C.sub.20 alkenoxy, C.sub.1 -C.sub.20 -alkylsulfinyl, --CN, --CF.sub.3, --NO.sub.2, --Si(CH.sub.3).sub.3 or --COO(C.sub.1 -C.sub.12 alkyl), are suitable, when incorporated into polymers having hydroxyalkyl groups, for currentless deposition of metals onto the polymer surface. They are in some cases suitable as photoinitiators.
摘要:
Substituted or unsubstituted tetrathio-, tetraseleno- or tetratelluronaphthalenes or -tetracenes form electrically conducting networks of crystal needles with electron acceptors, in particular with halogen-containing organic compounds, on a substrate. These needle networks can be coated electrolytically with metals and/or can be peeled off together with polymers from the substrate in the form of films which are electrically conducting on one side.
摘要:
Naphthacene-5,12-diones which are substituted by at least one organic thio radical are not only photoinitiators for the photopolymerization but also sensitizers for the photodimerization of ethylenically unsaturated compounds. Compositions made of these naphthacene-5,12-diones and ethylenically unsaturated compounds are suitable for the preparation of printing inks, paints, printing plates, resist materials or as image recording material.
摘要:
Polymers consisting of (a) vinyl compounds having a 2,2'-bipyridyl side group, (b) vinyl compounds having a radiation-sensitive side group and, if appropriate, (c) olefines which differ from (a) and (b), and their complexes with metal compounds, with the exception of alkali metal and alkaline earth metal compounds. They are suitable for coating substrates and for the preparation of photographic relief images. Complexes with cobalt salts are effective catalysts for the polymerization of acetylene.

In the case of a reinforcing system for reinforcing a cavity of a structural element, a support element is connected to the structural element in the structural element for reinforcement purposes. The support element has channels, an adhesive is disposed in the cavity between the support element and the structural element, and the adhesive can be introduced into the cavity between the support element and the structural element by means of the channels.

The invention relates to a filler material, especially for filling cavities, especially of structural elements, to a method of production and to a structural element. The inventive filler material comprises particles that are coated with a reactive duroplast, whereby the reactive duroplast is non-viscous at room temperature when not yet reacted.
