Method for producing a pattern on a transparent substrate

A method for producing a pattern on a transparent substrate comprising:

• a) depositing on at least one area of one of the faces of the substrate a first layer of a photosensitive resin comprising at least one sensitizing agent and at least one photosensitive compound essentially composed of a polymer with an average degree of cross-linking such that it is able to absorb solid particles;
• b) exposing certain areas of said first layer to light to increase the average degree of cross-linking of said polymer wherein the absorption capacity of the polymer is modulated as a function of light exposure;
• c) depositing on said first layer at least one second layer of a mineral particle containing composition that includes an enamel composition that comprises at least one glass frit and pigments;
• d) removing excess enamel not absorbed in the first layer;
• and
• e) repeating steps a), b), c) and d) a plurality of n times in succession on the same area is with the alternating deposition of a photosensitive hydrophilic resin and a photosensitive hydrophobic resin, and each of the enamel compositions contains black, white, or single-color pigments as its majority constituent
• e) subjecting said substrate to a first treatment cycle in order to fix said enamel in said second layer.

A method of manufacturing a decorative glass substrate comprising:

• a) providing a transparent substrate and depositing on at least one area of one of the faces of the substrate a first layer of a photosensitive resin comprising at least one sensitizing agent and at least one photosensitive compound essentially composed of a polymer with an average degree of cross-linking such that it is able to absorb solid particles;
• b) exposing certain areas of said first layer to light to increase, the average degree of cross-linking of said polymer wherein the absorption capacity of the polymer is modulated as a function of light exposure;
• c) depositing on said first layer at least one second layer of a mineral particle containing composition having a particle size that can be absorbed by the unexposed areas of the first layer;
• d) removing particles of the second layer not absorbed in the first layer;
• and
• e) subjecting said substrate to at least one heat treatment cycle in order to fix said mineral particles in the second layer;
• wherein the decorative glass substrate includes a glass-covered luminous sign, a glass oven door with an oven molding, a display window, and a stained-glass window.

A method of manufacturing a substrate that forms the front of a flat emittive screens comprising the steps of:

• a) providing a transparent substrate and depositing on at least one area of one of the faces of the substrate a first layer of a photosensitive resin comprising at least one sensitizing agent and at least one photosensitive compound essentially composed of a polymer with an average degree of cross-linking such that it is able to absorb solid particles;
• b) exposing certain areas of said first layer to light to increase, the average degree of cross-linking of said polymer wherein the absorption capacity of the polymer is modulated as a function of light exposure;
• c) depositing on said first layer at least one second layer of a mineral particle containing composition having a particle size that can be absorbed by the unexposed areas of the first layer;
• d) removing particles of the second layer not absorbed in the first layer;
• and
• e) subjecting said substrate to at least one heat treatment cycle in order to fix said mineral particles in the second layer.
