Abstract
Sublimable pad-printing ink and a method of marking an object with the ink, wherein the ink includes a hardening transparent pad-printing ink base and at least one sublimable colored pigment. The hardening transparent pad-printing ink base resists a sublimation temperature of the at least one sublimable colored pigment. The method includes pad-printing the object with a marking that includes a monochrome or polychrome marking composition having at least one monocolor pigmented component including fine particles of at least one sublimable monocolor colored pigment and heating at least one of the object and the pad-printed marking composition.

A method of marking an object comprising:
- pad-printing the object with a marking comprising one of a monochrome or polychrome marking composition having at least one monocolor pigmented component comprising fine particles of at least one sublimable monocolor colored pigment;
- and
- heating at least one of the object and the pad-printed marking composition,
- wherein the heating comprises sublimation heating which progressively cures a base prior to sublimation the fine particles of the at least one sublimable monocolor colored pigment, whereby the base acts as a screen for pigment vapors which migrate into a surface of the object, and whereby the base channels the pigment vapors towards the surface of the object so as to migrate into the surface.

A method of marking an object comprising:
- pad-printing the object with a marking comprising one of a monochrome or polychrome marking composition having at least one monocolor pigmented component comprising fine particles of at least one sublimable monocolor colored pigment, wherein the one of monochrome or polychrome marking composition includes at least one hardening component having a hardening temperature lower than the sublimation temperature of the at least one sublimable monocolor colored pigment;
- and
- heating, at a temperature at least equal to a sublimation temperature of the at least one sublimable monocolor colored pigment, at least one of the object, the pad-printed marking composition, and the hardening component.
A method of marking an object comprising:
- pad-printing the object with a marking comprising one of a monochrome or polychrome marking composition having at least one monocolor pigmented component comprising fine particles of at least one sublimable monocolor colored pigment;
- coating the pad-printed marking composition with a hardening component that resists a sublimation temperature of the at least one sublimable monocolor colored pigment;
- and
- after the coating, heating at least one of the object, the hardening component, and the pad-printed marking composition.

A method of marking an object comprising:
- pad-printing the object with a marking comprising one of a monochrome or polychrome marking composition having at least one monocolor pigmented component comprising fine particles of at least one sublimable monocolor colored pigment, wherein the one of monochrome or polychrome marking composition includes at least one hardening component having a hardening temperature lower than the sublimation temperature of the at least one sublimable monocolor colored pigment and wherein the hardening component is mainly comprised of a hardening transparent pad-printing ink base;
- and
- heating at least one of the object and the pad-printed marking composition.
A method of marking an object comprising:
- pad-printing the object with a marking comprising one of a monochrome or polychrome marking composition having at least one monocolor pigmented component comprising fine particles of at least one sublimable monocolor colored pigment, wherein the one of monochrome or polychrome marking composition includes at least one hardening component having a hardening temperature lower than the sublimation temperature of the at least one sublimable monocolor colored pigment and wherein the fine particles of at least one sublimable monocolor colored pigment are capable of being dispersed directly in the hardening component without and
- heating at least one of the object and the pad-printed marking composition.
A method of marking an object having a surface made of plastic comprising:
- pad-printing the surface with a marking comprising one of a monochrome or polychrome marking composition having at least one monocolor pigmented component comprising fine particles of at least one sublimable monocolor colored pigment;
- and
- heating the surface and the pad-printed marking composition,
- wherein the one of monochrome or polychrome marking composition includes at least one hardening component,
- wherein the at least one hardening component resists a sublimation temperature of the at least one sublimable monocolor colored pigment, and
- wherein the heating comprises heating at a temperature at least equal to a sublimation temperature of the at least one sublimable monocolor colored pigment.
