摘要:
The present invention provides modified multifunctional thiol-ene monomers wherein one or more thiols are reacted with a Michael addition reactive double bond compound. The present invention further discloses photocurable thiol-ene formulations comprising thiol-ene monomers including the modified multifunctional thiols. The present invention further discloses photocurable thiol-ene formulations comprising thiol-ene monomers and Michael addition reactive double bond molecules and a Michael catalyst. The formulations of the present invention can be photocured to make films or coatings. In a further disclosure, the formulations, including those comprised of unmodified multifunctional thiols and multifunctional enes, are photocured to form films applied to non-flexible or flexible polymer or non-polymer substrates suitable for food packaging, electronic products, optical products and other applications and free-standing films. The present invention further discloses photocurable thiol-ene formulations comprising thiol-ene monomers and Michael addition reactive double bond molecules and a Michael catalyst. These formulations are disclosed to form free-standing films and coatings on substrates when applied to flexible substrates. Such materials are suitable for use in the packaging of food products and other products which are to be maintained in a hermetically sealed relationship to the atmosphere.
摘要:
The present invention discloses a method of photolytically developing a walnut wood color on a wood sample. The sample is contacted with a salt of an aminobenzenesulfonyl azide. The sample is thereafter exposed to a light source for an amount of time sufficient to produce a walnut wood color thereon.
摘要:
The invention is directed to a coating system which is adaptable to being crosslinked subsequent to being embossed. The system comprises a linear polyurethane that contains sites of unsaturation only in its polymeric backbone and a photoinitiator. The polyurethane is produced by the reaction of a diisocyanate and an unsaturated polyester diol.
摘要:
The present invention discloses a method of photolytically developing a colored image on a cellulosic material. In this method, the material is contacted with a nitrogen containing polymer in solution and a mono-sulfonyl azide compound in solution. The sample is thereafter exposed to a UV-containing light source for an amount of time sufficient to develop a color thereon.
