| titleOfInvention | Radiation curable resin composition for use in magnetic recording media |
| abstract | Disclosed is a radiation curable resin composition permitting good dispersion of magnetic powders and forming a highly durable cured film, and hence suitable for use in the formation of magnetic recording media. This resin composition consists essentially of a urethane (meth)acrylate obtained by the reaction of n (A) a hydroxyl-containing compound (I) composed of an amido hydroxy compound (a 1 ) having at least one amido group and at least one isocyanate-reactive hydroxyl group in the molecule, and at least one polyol compound (a 2 ) selected from polyester polyols, polyether polyols and alkyl polyols, the number of moles (x 1 ) of the hydroxyl groups present in the amido hydroxy compound (a 1 ) being from 5 to 80% of the total number of moles of the hydroxyl groups contained in component (A) and the number of moles (x 2 ) of the hydroxyl groups present in the polyol compound (a 2 ) being from 95 to 20% of the total number of moles of the hydroxyl groups contained in component (A); n (B) a polyisocyanate compound having two or more isocyanate groups in the molecule; n (C) a phosphoric ester of the general formula ##STR1## where R is hydrogen or methyl, A is a divalent alcohol residue, R' is hydrogen or an alkyl group of 1 to 4 carbon atoms, and m is 1 or 2; and n (D) a hydroxyl-containing alkyl (meth)acrylate other than component (C), n the urethane (meth)acrylate being further characterized in that, when the number of moles of the hydroxyl groups present in component (A) is represented by X and the number of moles of the isocyanate groups present in component (B) is represented by Y, the ratio of X to Y ranges from 1:1.1 to 1:2, the number of moles (Z) of the hydroxyl groups present in components (C) and (D) is not less than (Y-X), and the number of moles of component (C) is between 0.1 (Y-X) and 0.7 (Y-X), both inclusive. |
