Inkjet printheads containing epoxy adhesives and methods for fabrication thereof

An inkjet printhead comprising:

• a first plate;
• a second plate;
• a cured thin film adhesive disposed between and bonding to both of the first plate and the second plate, wherein the cured thin film adhesive comprises a metal layer or a polymer film disposed between a cured first adhesive layer and a cured second adhesive layer,
• wherein curing of a first adhesive layer and a second adhesive layer at a temperature of less than about 200° C. while the first adhesive layer, metal layer or polymer film, and second adhesive layer are disposed between the first plate and the second plate results in the bonding of the cured thin film adhesive to the first plate and the second plate and both of the cured first adhesive layer and the cured second adhesive layer have a Tg of greater than about 115° C. and are stable when exposed to acrylate monomer, and
• wherein at least one of the first adhesive layer and the second adhesive layer comprises an epoxy novolac and an amine.

A method of producing an inkjet printhead comprising:

• placing a thin film adhesive between a first plate and a second plate;
• curing at a temperature of less than about 200° C. the thin film adhesive as it is in contact with both surface of the first plate and the second plate, thereby bonding the cured thin film adhesive to both of the first plate and the second plate,
• wherein the cured thin film adhesive comprises a metal layer or a polymer film disposed between a cured first adhesive layer and a cured second adhesive layer,
• wherein the cured first adhesive layer and the cured second adhesive layer have a Tg of greater than about 115° C. and are stable when exposed to acrylate monomer, and
• wherein at least one of the first adhesive layer and the second adhesive layer comprises an epoxy novolac and an amine.
