    摘要： The invention relates to a cladding resin composition curable by heat, ultraviolet radiation, an electron beam or the like. The composition comprises a polyoxyalkylene polyol phosphate ester (hydroxyl value: 10-2,000 mg KOH/g) and a polymerizable or reactive functional group-containing compound. This composition is highly conductive as it is and, without incorporation of the conventional conductive additives, can be used successfully in the field of coatings and protective films where electric conductivity is a requisite.

    摘要： A polyurethane resin is synthesized from a reaction mixture of at least one phosphorus compound, an epoxy compound, a polyisocyanate, a polyfunctional hydroxy compound, and optionally a chain extender. The polyurethane resin contains one phosphoric acid group or one residual group derived from phosphoric acid per 3,000 to about 200,000 number average molecular weight of the polyurethane resin. The weight average molecular weight of the polyurethane resin is from about 10,000 to about 250,000. A magnetic coating formulation is comprised of principally of magnetic particles and a binder. A magnetic recording media comprises a laminate as in the form of a magnetic layer composed principally of magnetic particles and a binder wherein at least a portion of the binder is the polyurethane resin. The substrate of the magnetic recording medium is a suitable polymer such as polyester, and the like. The utilization of the polyurethane resin containing a phosphorus compound therein results in excellent dispersion of the magnetic particles as well as exceptional durability.

    摘要： A magnetic coating formulation is composed principally of magnetic particles and a binder. At least a portion of the binder is a polyurethane resin synthesized from a reactant mixture of specific phosphorus compound, epoxy compound, isocyanate compound and polyfunctional hydroxy compounds. The reactant mixture may optionally contain a chain extender. The polyurethane resin contains one phosphoric acid group or one residual group derived from phosphoric acid per 3,000-200,000 number average molecular weight of the polyurethane resin, and has a number average molecular weight of 4,000-150,000. A magnetic recording medium with a magnetic coating layer formed from the magnetic coating formulation is also disclosed. The magnetic coating layer features not only excellent dispersion of magnetic particles, in other words, excellent magnetic characteristics but also superb durability.

    摘要： The invention comprises a phosphorus-containing polyether obtainable by reacting an epihalohydrin and a polyol component which comprises a sugar alcohol containing 5 or 6 carbons, a triol and orthophosphoric acid as described below. The reaction is suitably effected in the presence of an acidic fluorine-containing compound as catalyst, e.g. fluoboric acid. The term orthophosphoric acid includes strong phosphoric acid which contains in addition to orthophosphoric acid, pyrophosphoric acid and possibly higher polyphosphoric acids. In an example a mixture of glycerine, sorbitol and phosphoric acid is heated to 85 DEG C., fluoboric acid is added as catalyst and the temperature maintained between 86 DEG C. and 92 DEG C. during the addition of epichlorhydrin, and the mixture allowed to stand for 2 hours after the addition. The reaction mass is neutralized with triethanolamine. The epihalohydrin is preferably epichlorhydrin and the ratio of the number of moles of epihalohydric to the number of hydroxyl groups in the polyol component is preferably 0.5: 1 to 6: 1. The polyol component is preferably a mixture of from 80 to 30 equivalent weight per cent of the sugar alcohol, preferably sorbitol, and 20 to 70 equivalent weight per cent of the triol, preferably glycerine, and orthophosphoric acid taken together, and the amount of orthophosphoric acid is preferably such that the polyether contains 0.3 to 2.5% by wt. of combined phosphorus.
