摘要： A liquid electrophotographic (LEP) ink composition is described. The composition comprises: a pigment particle having an acidic surface modification; a basic charge director selected from:(i) a polymeric amine dispersant having a Total Base Number of at least 100 mg KOH/gram material, and (ii) a sulfosuccinate salt of the general formula MAn, wherein M is a metal, n is the valence of M, and A is an ion of the general formula (I): [R1—O—C(O)CH2CH(SO3)C(O)—O—R2]− (I); and a liquid carrier. The ink composition does not include a thermoplastic resin. Also described are a method of producing the ink composition, and a method of printing using the ink composition.

摘要： An article comprising a heater that comprises a high-resistance magnification (HRM) PTC ink deposited on a flexible substrate to form one or more resistors. The HRM PTC ink has a resistance magnification of at least 20 in a temperature range of at least 20 degrees Celsius above a switching temperature of the ink, the resistance magnification being defined as a ratio between a resistance of the double-resin ink at a temperature ‘T’ and a resistance of the double-resin ink at 25 degrees Celsius.

摘要： An article comprising a double-switching heater that comprises a double-switching PTC ink deposited on a flexible substrate to form one or more resistors. The double-switching PTC ink comprises a first resin and a second resin; the first resin provides a first PTC effect within a first temperature range (T1, T2); the second resin provides a second PTC effect within a second temperature range (T3, T4), where T3≥T2; the first resin has an NTC effect above the first temperature range; the second PTC effect is greater than the first PTC effect; and the second PTC effect overlaps with, and is greater than, the NTC effect of the first resin. The substrate can be either thermal polyurethane, nylon or a polyester blend.

摘要： A printed circuit that comprises a substrate, electrical interconnects and a double-resin ink having a positive temperature coefficient (PTC), wherein the double-resin ink has a resistance magnification of at least 20 in a temperature range of at least 20 degrees Celsius above a switching temperature of the double-resin ink, the resistance magnification being defined as a ratio between a resistance of the double-resin ink at a temperature ‘T’ and a resistance of the double-resin ink at 25 degrees Celsius. The substrate is a fabric or mesh, while the double-resin ink and the electrical interconnects are deposited onto the substrate.
