Abstract
Disclosed is an ink jet printhead containing a polymer of the formula ##STR1## wherein P is a substituent which enables crosslinking of the polymer, a, b, c, and d are each integers of 0, 1, 2, 3, or 4, provided that at least one of a, b, c, and d is equal to or greater than 1 in at least some of the monomer repeat units of the polymer, A is ##STR2## or a mixture of ##STR3## wherein R is a hydrogen atom, an alkyl group, an aryl group, or mixtures thereof, B is one of specified groups, such as ##STR4## or mixtures thereof, and n is an integer representing the number of repeating monomer units.
