- 8. The recording element of claim 5 which is a disc.
- 9. A phonograph record having upon its playing surface a composition comprising N-alkyl-substituted N,N-dialkanolamine having the formula:
- (HOR.sub.1).sub.2 N--R.sub.2
- wherein R.sub.1 is alkylene selected from the group consisting of ethylene, isopropylene and propylene and R.sub.2 is a hydrocarbon radical having about four to twenty carbon atoms.
