HIGH DENSITY INFORMATION RECORDS OF AN ELECTROSTATIC CAPACITANCE TYPE
摘要
<p>High density information records formed from conductive resin compositions which comprise a graft polymer obtained by subjecting vinyl chloride monomer to graft polymerization with a copolymer of ethylene and vinyl acetate having a content of vinyl acetate of not less than 35 wt % and a melt index up to 20 and prepared according to a solution polymerization technique. The conductive composition further comprises predetermined amounts of a conductive material and a lubricant of a specific type. The lubricant is an ester between aliphatic acid and alcohol having a hydroxyl value not larger than 15.</p>
