Hot melt ink jet transparency

摘要

In the particular embodiments of the invention described in the specification, a transparency includes a transparent substrate made of a polyester material, a colored ink pattern disposed on one surface of the transparent substrate in the form of three-dimensional ink spots having curved surfaces, and spots of a colorless ink made of a material which has an index of refraction approximately the same as that of the colored ink spots deposited in overlapping relation to colored ink spots as to reduce the dispersion of light by those ink spots. In one embodiment, the colorless ink spots are located in regions having no colored ink spots and in another embodiment the colorless ink spreads to a greater extent than the colored ink.
