    Abstract: A process for obtaining a material including a glass sheet, includes providing a glass sheet including a first face coated at least partly by an essentially mineral first coating, the face having at least one first zone and at least one second zone, the at least one first zone having a higher emissivity than that of the second zone, then applying, on at least one portion of the second zone, a sacrificial layer including a resin, then heat treating the coated glass sheet at a temperature of at least 550° C., during which step the sacrificial layer is removed by combustion.

    Abstract: A glass substrate includes on a face a water-insoluble polymeric temporary protective layer intended to be removed by heat treatment during a processing operation, and an enamel layer that has a mixture of glass frit, inorganic pigments and organic components that is deposited on at least one portion of the protective layer. The enamel has a glass transition temperature Tg above the temperature Tc60%, defined as being the temperature at which 60% of the initial weight of the protective layer is consumed, a maximum shrinkage measured by thermomechanical analysis between 450° C. and 650° C. greater than 20%, a difference between the inflection point temperature Tinflection and the glass transition temperature Tg less than 60° C., the inflection point temperature being defined as being the temperature at which the rate of displacement measured by thermomechanical analysis of the enamel is maximum, and a content of inorganic pigments less than 35% by weight.
