Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
52 words
A print comprising a base material and a printing ink containing an infrared reflective coloring agent and another printing ink containing an infrared absorptive coloring agent applied in combination on the base material, whereby visually-recognizable information is provided along with other information, which is recognizable by infrared rays, on the base material.
Claim 2
Dependent Claim
52 words
A print comprising a base material and a printing ink containing an infrared reflective coloring agent and another printing ink containing an infrared absorptive coloring agent applied in combination on the base material, whereby visually-recognizable information is provided along with other information, which is recognizable by infrared rays, on the base material.
Claim 3
Dependent Claim
56 words
The print as claimed in Claim 1, wherein the infrared reflective coloring agent is a coloring agent selected from the group consisting of chromatic and black coloring agents of the azo, anthraquinone, phthalocyanine, perinone·perylene, indigo·thioindigo, dioxazine, quinacridone, isoindolinone, chromatic iron oxide and chromatic spinel-structured types, or a mixture of at least two coloring agents selected therefrom.
