Meltable reactive ink and process of using same

A method of digital printing, comprising the steps of:

• a. preparing an ink that is solid at ambient temperature, said ink comprising a colorant, a first reagent, a second reagent that reacts with said first reagent, and a blocking agent which, during storage and printing of said ink, prevents a reaction between said first reagent and said second reagent;
• b. supplying a digital printer which uses solid ink with said ink;
• c. applying heat to said ink to melt said ink, wherein said ink melts at a temperature that does not materially disable said blocking agent from materially inhibiting a reaction between said first reagent and said second reagent;
• d. melting said ink and printing said ink onto a substrate to form an image on said substrate;
• and
• e. subsequently disabling said blocking agent and reacting said first reagent and said second reagent to bond said image to said substrate.

A method of digital printing, comprising the steps of:

• a. preparing an ink that is solid at ambient temperature, said ink comprising a first reagent, a second reagent that reacts with said first reagent, a catalyst that facilitates a reaction between said first reagent and said second reagent, wherein said catalyst comprises a blocking agent, and wherein said blocking agent materially inhibits said catalyst from facilitating a reaction between said first reagent and said second reagent;
• b. supplying a digital printer which uses solid ink with said ink;
• c. applying heat to said ink to melt said ink, wherein said ink melts at a temperature that does not materially disable said blocking agent from materially inhibiting a reaction between said first reagent and said second reagent;
• d. melting said ink and printing said ink onto a substrate to form an image on said substrate;
• and
• e. subsequently disabling said blocking agent and reacting said first reagent and said second reagent to bond said image to said substrate.
