Abstract

1. Mejoras en un procedimiento para la preparación de un material registrador sensible a la presión constituido por una hoja de microcápsulas que contiene un agente básico formador de color, esencialmente incoloro, que cambia a una forma coloreada por interacción con fibras celulósicas y que tiene un coeficiente de extinción molecular en etanol no inferior a 100, y una hoja de papel donde se forma el color, consistiendo dicho procedimiento en: a) formar microcápsulas que contienen el agente básico formador del color; b) combinar sobre una hoja de papel un ligante y las microcápsulas del apartado anterior y c) sacar la hoja de mircrocápsulas así obtenida; cuyas mejoras consisten en emplear como papel donde se forma el color, una hoja de celulosa que contiene un pigmento inorgánico adsorbente de aceite.
