A method of reducing thickness non-uniformity in a microjet-deposited solids layer is disclosed which comprises depositing onto a substrate by microjet deposition a composition containing a liquid vehicle, at least one reagent; and a polyol which is present at a concentration that enhances thickness uniformity of a solids layer, containing the reagent(s), which is formed by the microjet-deposited composition is dried. L'invention concerne un procédé de réduction de la non-uniformité d'épaisseur d'une couche de solides déposée par microjets qui comprend le dépôt sur un substrat par dépôt de microjets d'une composition contenant un véhicule liquide, au moins un réactif; et un polyol qui est présent à une concentration qui accentue l'uniformité d'épaisseur d'une couche de solides, comprenant le ou les réactifs, qui sont formés par la composition déposée par microjets qui est séchée.
