Pattern forming method and ink compostion

A method of forming a phosphor pattern on a glass substrate comprising the steps of:

• forming a tacky layer on said glass substrate;
• filling a pattern of grooves formed on an intaglio with a mixture of at least a photo-absorbent powder and an ink mainly composed of a resin which is removable by pyrolysis or combustion to form a pattern of the mixture on said intaglio;
• transferring said pattern of the mixture on said intaglio onto a surface of a blanket whose surface is covered with an elastic material to form a pattern of the mixture on said blanket;
• forming a pattern of a phosphor layer on said photo-absorbing pattern;
• and
• firing said glass substrate.

• transferring said pattern of the mixture on said blanket onto said tacky later formed on said glass substrate to form a pattern of the mixture on said tacky layer;
• and
• firing said glass substrate.

A method of forming a color filter comprising the steps of:

• forming a tacky layer on a glass substrate;
• filling a pattern of grooves formed on an intaglio with a mixture of at least a color pigment and an ink mainly composed of a resin to form a pattern of the mixture on said intaglio;
• transferring said pattern of the mixture on said intaglio onto a surface of a blanket whose surface is covered with an elastic material to form a pattern of the mixture on said blanket;
• and
• transferring said pattern of the mixture on said blanket onto said tacky layer formed on said glass substrate to form a pattern of the mixture on said tacky layer to thereby obtain a color filter.

A method of forming a cathode-ray tube anode comprising the steps of:

• forming a tacky layer on a glass substrate;
• forming a pattern of a graphite ink on an intaglio;
• transferring said pattern of the graphite ink onto a surface of a blanket whose surface is covered with an elastic material;
• transferring said pattern of the graphite ink on said blanket onto said tacky layer formed on said glass substrate to thereby form a black matrix layer;
• forming a pattern of a phosphor ink on an intaglio;
• transferring said pattern of the phosphor ink onto a surface of a blanket whose surface is covered with an elastic material;
• transferring said pattern of the phosphor ink on said blanket onto said glass substrate on which said black matrix layer has been formed to thereby form a phosphor layer;
• forming a metal-back layer by covering said black matrix layer and said phosphor layer with an aluminum thin film having formed thereon a plurality of pores;
• and
• firing said glass substrate.
