Title
(EN) RECEIVER MEDIUM FOR INK JET PRINTING
(FR) SUPPORT RECEPTEUR D'IMPRESSION A JET D'ENCRE
Abstract
(EN)
A receiver medium for use with oil-based ink jet printing ink comprises a substrate having an ink receiving surface bearing a coating of a mixture of optionally substituted polybutadiene emulsion, particularly polybutadiene emulsion or polyisoprene emulsion (e.g. a natural rubber latex), and colloidal inorganic material, e.g. an alumina or silica sol. The coating is capable of absorbing oil and use of such a coating can thus enable oil-based inks to be printed successfully onto non-absorbent substrates, including optically transparent media such as polyethylene terephthalate films, e.g. for the production of transparency sheets for use in OHPs, in a way that has not hitherto been possible. The substrate may alternatively be absorbent and may itself act to absorb some of the oil from applied ink. The invention also covers a method of making the medium and a method of printing using the medium.
(FR)
L'invention concerne un support récepteur utilisé avec une encre d'impression à jet d'encre à base d'huile comprenant un substrat présentant une surface de réception de l'encre enduite d'un revêtement d'un mélange d'émulsion de polybutadiène éventuellement substitué, plus précisément une émulsion de polybutadiène ou une émulsion de polyisoprène (par exemple un latex caoutchouc naturel) et une matière inorganique colloïdale, par exemple un sol d'alumine ou de silice. Le revêtement peut absorber l'huile et l'utiliser comme revêtement qui permet l'impression des substrats non absorbants avec des encres à base d'huile, notamment des supports optiquement transparents tels que des films de polyéthylène térephtalate, en vue notamment de la production de feuilles transparentes utilisées dans les rétroprojecteurs ce qui n'était pas viable jusqu'à présent. Selon une variante, le substrat peut être absorbant et peut servir à absorber une partie de l'huile de l'encre appliquée. L'invention concerne aussi un procédé de production de ce support et un procédé d'impression utilisant ce support.
