A pattern carrier for use in transfer pattern printing of textiles comprises paper with an air permeability (Bendtsen-porosity) of more than 500 ml/min and a water absorption corresponding to a Cobb-number of at least 50, said paper being coated with an aqueous dispersion of carboxymethylcellulose containing a non-crystallizing saccharide syrup, preferably in an amount of approximately 30 g of dispersion per m2, whereafter one or more colour patterns are printed on said paper, each colour pattern comprising a water-soluble or dispersible dye admixed an easily soluble thickening carrier with a temporary binding effect, preferably in form of carboxymethylcellulose. The use of a saccharide syrup, preferably a sorbitol syrup, for the coating renders it possible to use standard-absorbing crude paper as the basis of the pattern carrier, which provides obvious financial and production-related advantages.

L'invention concerne un support de modèle à utiliser dans l'impression de modèles par transfert sur des tissus comprenant du papier dont la perméabilité à l'air (porosité Bendtsen) est supérieure à 500 ml/min et dont l'absorption de l'eau correspond à un indice de Cobb d'au moins 50. Ce papier enduit d'une dispersion aqueuse de carboxyméthylcellulose renferme un sirop de saccharide non cristallisé de préférence dans une quantité d'environ 30 g de dispersion par m<2>. Un ou plusieurs modèles de couleur sont imprimés sur ce papier, chaque modèle de couleur comprenant une matrice hydrosoluble ou dispersable mélangée à un support épaississant facilement soluble présentant un effet de liaison temporaire, de préférence sous forme de carboxyméthylcellulose. L'utilisation d'un sirop de saccharide, de préférence un sirop sorbitol, pour l'enduction permet l'utilisation de papier brut absorbant standard comme base du support de modèle qui offre des avantages indéniables en termes de coûts et de production.
