Title (EN) WASHABLE NON-SPLATTER INK
(FR) ENCRE LAVABLE QUI NE BAVE PAS
Abstract: front page image
(EN)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.
(FR)Encre lavable qui ne bave pas utilisable pour les enregistreurs a plume oscillographiques. L"encre se caracterise par sa stabilite a temperature ambiante pendant de longues periodes de temps sans qu"elle soit necessaire de la refroidir pour conserver sa stabilite. L"encre contient un polyacrylamide d"un poids moleculaire eleve au lieu de contenir de l"oxyde de polyethylene, comme agent de cohesion pour arreter les bavures de l"encre aux grandes vitesses d"ecriture. Le polyacrylamide permet l"utilisation de colorants acides lavables. L"incorporation d"un alcool non-sature, tel que le butynediol retarde l"oxydation de l"agent de cohesion en le stabilisant et en le protegeant contre la degradation due au vieillissement.
