<p>An aperture plate including a first layer having a first emissivity; a second layer having a second emissivity disposed over the first layer; wherein the first emissivity is higher than the second emissivity; and optionally, at least one additional layer disposed over the second layer. A method for preparing an aperture plate including providing a first layer having a first emissivity; disposing a second layer having a second emissivity over the first layer; wherein the first emissivity is higher than the second emissivity; optionally, disposing at least one additional layer over the second layer; and forming at least one aperture, wherein aperture formation can be before or after disposing the second layer over the first layer. An ink jet print head having an aperture plate including a first layer having a first emissivity; a second layer having a second emissivity disposed over the first layer; wherein the first emissivity is higher than the second emissivity; optionally, at least one additional layer disposed over the second layer; wherein one of the optional at least one additional layers disposed over the second layer is a coating layer for controlling surface tension.</p> |
