Abstract: Solid aromatic or cycloaliphatic azole-aldehyde addition products can be used as chemical embossing inhibitors. Most of the addition products 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 adducts of azole derivatives (benzotriazole and benzimidazole) reacted with aldehydes.

Abstract: Thermal insulation is prepared using gelatin foam. Embodiments of gelatin foam insulation which are described include gelatin foam having an anti-wicking agent which is an aromatic compound having as ring substituents: an --NH.sub.2 moiety and/or a hydroxyl moiety and also at least two sulfonate moieties. In another embodiment, the gelatin foam is combined with phyllosilicate mineral lamellae for void control and as a shrinkage deterrent. In yet another embodiment, crosslinked gelatin foam is described which has been crosslinked with a melamine/formaldehyde condensation product, a polyfunctional aziridine and/or an epichlorohydrin/polyamide condensation product.

Abstract: 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.
