Claims16
A coating composition for applying an antistatic layer to a surface comprising a hydrophobic binder and an antistatic polymer having the formula:
- ##STR7## wherein:
- A represents units of an addition polymerizable monomer containing at least two ethylenically unsaturated groups;
- B represents units of a copolymerizable .alpha., .beta.-ethylenically unsaturated monomer;
- Q is N or P;
- R.sup.1, R.sup.2 and R.sup.3 are independently selected from the group consisting of carbocyclic and alkyl groups;
- M- is an anion;
- x is from about 0.1 to about 20 mole percent;
- y is from about 0 to about 90 mole percent;
- and
- z is from about 10 to about 99 mole percent;
- in a solvent mixture comprising from 8 to 30 percent by weight of n-propyl acetate, 1-methoxy-2-propanol or cyclohexane;
- from 50 to 55 weight percent of acetone and the balance methanol.
