    • New ink-jet printing inks provide red printed images with high-intensity fluorescence emission and are capable of printing images that can be used for high density bar code applications (2D bar codes) having high readability. The inks are aqueous and capable of producing machine-readable markings exhibiting fluorescence when exposed to fluorescent-exciting radiation. They exhibit a peak of fluorescence between about 500 nm and about 700 nm and a fluorescent strength of the ink diluted by 100 times of more than about 70 by excitation of ultraviolet radiation. The inks exhibit a peak of absorbance of between about 400 nm and about 600 nm, and an absorbance of the ink diluted by 100 times and measured in 1 mm cell of more than about 0.6. The preferred inks are characterized by a color of the ink diluted by 100 times with water and measured in 1 mm cell is t L*: about 80±10, a*: about 45±20, b*: about 20±35 and a color of the printed image of L*: about 65±10, a*: about 55±10, b*: about 5±20. Compositionally, the preferred inks are comprised of a dye selected from the group consisting of C.I. Acid Red 52, C.I. Acid Red 87 and C.I. Acid Red 92. In some preferred inks, the absorption coefficient to paper is between about 0 mL/m2sec1/2 and about 130 mL/m2sec1/2 by the measurement of the Bristow method.
    • 新的喷墨印刷油墨提供具有高强度荧光发射的红色印刷图像,并且能够打印可用于具有高可读性的高密度条形码应用(2D条形码)的图像。 油墨是水性的,并且能够产生当暴露于荧光激发辐射时显示荧光的机读标记。 它们表现出约500nm至约700nm之间的荧光峰值,并且通过紫外线辐射的激发使得油墨的荧光强度被稀释为大于约70的100倍。 油墨的吸光度峰值在约400nm至约600nm之间,并且油墨的吸光度被稀释100倍,并且在1mm单元格中测量的吸光度大于约0.6。 优选的油墨的特征在于用水稀释100倍的油墨的颜色,并且在1mm细胞中测量为t L *:约80±10,a *:约45±20,b *:约20±35和 L *的印刷图像的颜色:约65±10,a *:约55±10,b *:约5±20。 在组成上,优选的油墨由选自C.I. 酸性红52,C.I。 酸性红87和C.I. 酸性红92.在一些优选的油墨中,对纸的吸收系数为约0mL / m 2 / sec 1/2至约130mL / m 2 通过Bristow方法的测量,秒<1/2>
