  • Patent number: 4889895
    Abstract: Magnetic recording media have been made with a new class of binder resins having the formula ##STR1## wherein the portion of the copolymer having the a subscript comprises 50 to 97 weight percent of the copolymer, the portion of the copolymer having the b subscript comprises 0 to 30 weight percent of the copolymer, the portions of the copolymer having the c and d subscripts combinec comprise, 0.1 to 20 weight percent of the copolymer, while d can be 0,R.sub.1 is an alkyl group selected from --CH.sub.3 and --(CH.sub.2).sub.n1 CH.sub.3 wherein n1=1-10,R.sub.2 is an alkylene group which may be --CH.sub.2).sub.n1 or --CH.sub.2).sub.n2 (CH)(CH.sub.2).sub.n3 CH.sub.3, n2=1-4 and n3=0-4,R.sub.3 may be selected from --H and --CH.sub.3, n5=0 or 1, and X is a linking group which is stable under electron beam irradiation and may be, for example, ##STR2## R.sub.4 =C1-6 alkylene, for example, with the proviso that when d=0, there is at least one additional polymer in the binder.
