The encapsulation of pigment particles in an acrylate polymer is 
not a new idea.  20 years ago and maybe even longer  silkscreen 
inks for plastics used that concept. The encapsulated pigments 
were called pellets then if I remember it correctly.  The ink was 
considered more fade resistant and wasn't cheap. To make pellets 
small enough for use in inkjets must have been a difficult task 
but getting a patent even more difficult.
