Abstract

Mejoras introducidas en la fabricación de hojas copiadoras sensibles al calor que tienen resistencia mejorada al oscurecimiento bajo la luz solar directa y que incluyen una capa sensible al calor que comprende un jabón de ácido orgánico de un metal noble, un agente reductor orgánico para los iones del metal noble, y caracterizadas porque dicha capa sensible al calor incluye una proporción pequeña importante de un componente estabilizador que tiene uno o más radicales de etilenimina activados con la estructura *** ver imagen 01 donde R¿ y R¿¿ representan hidrógeno o un radical alcohilo inferior.
