Intaglio printing inks with unique rheological properties have been discovered. The intaglio printing inks are extremely dependent on temperature and almost independent of shear. The intaglio printing inks preferably are low in volatile organic components. The intaglio printing inks, because of the unique rheological properties exhibited, are excellent for intaglio printing on Tyvek and paper, for example, in the printing of security documents such as currency, postage stamps, stock certificates, bank notes and the like. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader quickly to ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the appended issued claims. 37 CFR .xi. 1.72(b).
La présente invention concerne des encres d'impression en creux présentant des propriétés rhéologiques uniques. Ces encres d'impression en creux sont extrêmement dépendantes de la température et quasiment indépendantes du cisaillement. Lesdites encres d'impression en creux présentent de préférence une faible teneur en composants organiques volatils. En raison de leurs propriétés rhéologiques uniques, les encres d'impression en creux sont excellentes pour une impression en creux sur du Tyvek et du papier, par exemple pour imprimer des documents de sécurité, tels que du papier-monnaie, des timbres postaux, des certificats d'actions, des billets de banque et similaire.
