    摘要: An alkoxysilane bearing amic acid or derivative thereof is formed by reacting an aromatic or aliphatic dianhydride and an aminoalkyltrialkoxysilane or aminoaryltrialkoxysilane, or reacting an aromatic or aliphatic dianhydride and a diamine to form an amic acid which is reacted with an aminoalkylenetrialkoxysilane. A thin, hard protective silica glass network is formed by reacting the alkoxysilane bearing amic acid with an alkoxysilane, preferably tetraalkoxysilane, and an epoxy bearing silane coupling agnet in an acid catalyzed sol-gel process involving hydrolysis and condensation, which provides an amide/ester modified silica network. In a variation of this process, a polyamic acid bearing anhydride termination is prepared by reacting an excess of a dianhydride with a diamine. The product of this reaction when reacted with an aminoalkylenetrialkoxysilane provides an alkoxysilane bearing oligomeric polyamic acid. The latter product yields an imide modified silica network when subjected to acid catalyzed hydrolysis and condensation with tetraalkoxysilane.

    摘要: A high melting solid aromatic or cycloaliphatic azole-based chemical embossing inhibitor is essentially insoluble and inert in water and/or water alcohol mixtures. These solid azoles can be readily micronized and dispersed into water-based printing inks for use in producing textured foamed plastic surfaces. These compounds comprise a general class of 1-N substituted aminomethylaryl- or cyclohexyltriazole and imidazole derivatives. Some of the preferred compounds are symmetrical di-functional triazole derivatives and some of the preferred embodiments have a carboxy moiety or a sulfonyl moiety attached to a nitrogen atom.
