ABSTRACT:
A recording sheet comprising a substrate and a coating consisting essentially of an optional binder, an optional filler, and quaternary ammonium polymers selected from ##STR1## wherein n is an integer from 1 to 200, R.sub.1, R.sub.2, R.sub.3, and R.sub.4 are selected from alkyl, hydroxyalkyl, and polyoxyalkylene, p is an integer from 1 to 10, q is an integer from 1 to 10, X is an anion, and Y.sub.1 is selected from --CH.sub.2 CH.sub.2 OCH.sub.2 CH.sub.2 --, --CH.sub.2 CH.sub.2 OCH.sub.2 CH.sub.2 OCH.sub.2 CH.sub.2 --, --(CH.sub.2).sub.k --, wherein k is an integer from 2 to 10, and --CH.sub.2 CH(OH)CH.sub.2 --; ##STR2## wherein wherein n is an integer from 1 to 200, R.sub.5, R.sub.6, R.sub.7, and R.sub.8 are selected from alkyl, hydroxyalkyl, and polyoxyalkylene, m is an integer from 0 to 40, r is an integer from 1 to 10, s is an integer from 1 to 10, X is an anion, and Y.sub.2 is selected from --CH.sub.2 CH.sub.2 OCH.sub.2 CH.sub.2 --, --CH.sub.2 CH.sub.2 OCH.sub.2 CH.sub.2 OCH.sub.2 CH.sub.2 --, --(CH.sub.2).sub.k --, wherein k is an integer from 2 to 10, and --CH.sub.2 CH(OH)CH.sub.2 --; ##STR3## wherein a and b are integers wherein the sum of a+b is from 2 to 200, R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5, R.sub.6, R.sub.7, and R.sub.8 are selected from alkyl, hydroxyalkyl, and polyoxyalkylene, p is an integer from 1 to 10, q is an integer from 1 to 10, X is an anion, and Y.sub.1 and Y.sub.2 are selected from --CH.sub.2 CH.sub.2 OCH.sub.2 CH.sub.2 --, --CH.sub.2 CH.sub.2 OCH.sub.2 CH.sub.2 OCH.sub.2 CH.sub.2 --, --(CH.sub.2).sub.k --, wherein k is an integer from 2 to 10, and --CH.sub.2 CH(OH)CH.sub.2 --. Mixtures of these polymers are also suitable.
