Abstract
Process comprising the following steps: a) deposition of a green layer based on 0.1% of an organic binder, on a mineral filler and on 0.1% to 13% of a mineral binder; b) formation of the barriers by spraying an abrasive material onto a mask applied against this layer, and then removal of the mask; c) deposition of a phosphor-based green layer; d) baking of the two layers, preferably simultaneously. By virtue of the limited amount of organic binder, the abrasion rate is high; if this content is at least 2%, deterioration of the green barriers is avoided.
