Claims (5)

1. Procédé pour préparer un papier comprenant, à des fins d'identification, un ou plusieurs pigments sous forme de granules inapparents en lumière du jour, mais visibles à l'examen dans un environnement assombri ou après éclairage à une longueur d'onde prédéterminée avec une source artificielle, caractérisé en ce que, pour assurer le contraste entre les granules de pigments et le fond dans un tel examen, sans que les granules de pigments individuels apparaissent, un pigment granulé préformé est sensiblement débarrassé des granules dont la taille est inférieure à 30 pm ou supérieure à 500 94m, puis est incorporé au papier.
2. Procédé selon la revendication 1, dans lequel la taille desdits granules incorporés est de 100 à 230 ou 250 µm.
3. Procédé selon la revendication 1 ou 2, dans lequel lesdits granules sont formés par broyage d'une résine contenant un colorant photoréactif ou sont des particules de résine photoréactive préformées liées pour former les granules.
4. Procédé selon la revendication 3, dans lequel la résine est liée par addition d'une certaine quantité d'un liant résineux liquide aux particules et brassage au tambour jusqu'à ce que les agrégats constituant les granules soient formés, cette quantité de liant étant suffisante pour agglomérer les particules, mais non pour former une phase liquide continue.
5. Procédé selon la revendication 4, dans lequel les particules préformées sont elles-mêmes des agrégats formés par un procédé semblable de brassage au tambour.
