Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
88 words
An ink jet printing process for an ink jet printing system which supplies an informational signal pulse, comprising the steps of providing an ink composition comprising a suspension of wax particles having a melting temperature less than about 150° C., and having an average particle diameter of about 0.01 micrometer to about 2 micrometers in a water phase and a colorant, said water phase present in an amount 50 to 99% by weight and jetting said ink composition onto a substrate in response to said informational signal pulse.
Claim 2
Dependent Claim
88 words
An ink jet printing process for an ink jet printing system which supplies an informational signal pulse, comprising the steps of providing an ink composition comprising a suspension of wax particles having a melting temperature less than about 150° C., and having an average particle diameter of about 0.01 micrometer to about 2 micrometers in a water phase and a colorant, said water phase present in an amount 50 to 99% by weight and jetting said ink composition onto a substrate in response to said informational signal pulse.
