For those in labor and delivery!

Resin

Noun:

1. Any of a class of nonvolatile, solid or semisolid organic substances, as copal or mastic, that consist of amorphous mixtures of carboxylic acids and are obtained directly from certain plants as exudations or prepared by polymerization of simple molecules: used in medicine and in the making of varnishes and plastics.

I'm taking a resin that was sythesized out of various monomers and "cutting" it by partially neutralizing it with ammonia in order to make it just soluble in water enough to disperse and then it's used in inks and other things to prevent agglomeration of the pigment particles.
