Provided is a method for creating an authentication mark on a recording medium comprising: (a) depositing marking material directly onto a recording medium or depositing marking material onto an intermediate transfer member, in an image area to create a marking material image and in an authentication image area to create a marking material authentication image, wherein the marking material is an ultraviolet curable phase change ink composition comprising an optional colorant and a phase change ink vehicle comprising a radiation curable monomer or prepolymer; a photoinitiator; a reactive wax; and a gellant; (b) depositing a predetermined amount of additional marking material upon the authentication image area to increase an amount of marking material associated with the marking material authentication image in the authentication image area; (c) when an intermediate transfer member is used, transferring the deposited marking material from the intermediate transfer member to the recording medium; and (d) curing the marking material upon the recording medium such that the fixed marking material associated with the authentication image area is a tactilely perceptible authentication mark, the fixed marking material associated with the tactilely perceptible authentication mark having a first height, the first height being tactilely perceptible
摘要:
A document includes paper having an average surface roughness of at least about 0.5 microns and including one or more optical brighteners, and includes at least one image thereon wherein the at least one image includes clear binder and light absorbing material that absorbs light only at wavelengths below 350 nm. The image is substantially not detectable to a naked human eye through differential gloss or exposure to light having wavelengths of 365 nm or more, but may be revealed to the naked human eye by exposing the document to light having a wavelength at which the light absorbing material absorbs light.
摘要:
It is provided an electrophoretic display device comprising a display layer comprised of a multiplicity of individual reservoirs containing a display medium over a conductive substrate, and a color filter layer over the display layer, wherein the display medium comprises a set of white particles dispersed in a dark colored dielectric fluid or a set of dark colored particles and a set of white particles dispersed in a clear dielectric fluid, the display medium having an electrical conductivity of about 10 -11 to about 10 -15 S/m, and wherein the color filter layer comprises each of a red tinted transparent portion, a blue tinted transparent portion and a green tinted transparent portion.
