Abstract: A polyurethane resin, which is soluble in organic solvents, is the product of at least one diisocyanate and a component having isocyanate reactive functional groups which include a first polyol group having an average molecular weight from 1000 to 10000 g/mol, a second polyol group having an average molecular weight from 10000 to 20000 g/mol, and a third polyol group having an average molecular weight not greater than 800 g/mol. The equivalent ratio of the diisocyanate to the components having isocyanate reactive functional groups is such that the resulting polyurethane resin has no unreacted polyisocyanate. When used as a film forming binder in inks, the resin provides excellent initial adhesion to plastic films.

Abstract: A polyurethane resin (soluble in organic solvents, preferably in alcohols) being in one embodiment of the present invention the reaction product of at least one diisocyanate components having isocyanate reactive functional groups, said components comprising a first group of at least one polyol, a second group of at least one polyol and a third group of at least one polyol, at least one amine and optionally a terminating agent wherein all polyols of said first group have an average molecular weight from 1000 to 10000 g/mol wherein all polyols of said second group have an average molecular weight from 10000 to 20000 g/mol, and wherein all polyols of said third group have an average molecular weight of equal to or less than 800 g/mol, and the ratio of the equivalent weights of the diisocyanate to the components having isocyanate reactive functional groups is selected such that essentially all of the isocyanate groups of the diisocyanate are present as the reaction product with one of said isocyanate reactive fun

Abstract: A portable device has a container portion for tools and materials and a handle for carrying and hanging, an electrical power supply section for obtaining power for and sending power to lights and tools, an illumination section for lighting a work area, and a base for standing the device on a surface. The device nests with other like devices when empty. The power cord preferably is stored on a reel within the base of the container, within the electrical section. The device enables tradesmen to be self-sufficient on a work site in building construction, providing light, storage, and power where needed, conveniently and inexpensively.
