Abstract: A washable non-splatter ink for use in oscillographic type pen recorders is disclosed. The ink is characterized by being stable at room temperature for extended periods of time, thus not requiring refrigeration for the maintenance of stability. The ink contains a high molecular weight polyacrylamide rather than polyethylene oxide as a pituity agent to stop splatter of the ink at fast writing speeds. The polyacrylamide allows the use of washable acid dyes. The inclusion of an unsaturated alcohol, such as butyne diol acts to retard the oxidation of the pituity, thus stabilizing the pituity against aging degradation.
