Abstract

Procédé de fabrication de feuilles d'enregistrement sans carbone sensibles à la pression. On prépare une composition d'enduction hot melt dont le point de fusion est compris entre 60 et 140 degrés C et qui comprend un matériau chromogène et un acide dioïque aliphatique solide Cette composition est déposée sur le substrat puis durcie par refroidissement. Le poids d'enduit est compris entre 0,3 et 12 grammes par mètre carré de substrat. Fabrication en continu de feuilles d'enregistrement et/ou de formulaires à copies multiples sans carbone sensibles à la pression.A method of manufacturing pressure sensitive carbonless recording sheets. A hot melt coating composition is prepared, the melting point of which is between 60 and 140 degrees C and which comprises a chromogenic material and a solid aliphatic dioic acid. This composition is deposited on the substrate and then cured by cooling. The coating weight is between 0.3 and 12 grams per square meter of substrate. Continuous manufacturing of pressure sensitive carbonless recording sheets and / or multiple copy forms.
