SELF-DISPERSING PARTICLES AND METHODS FOR MAKING AND USING THE SAME

摘要

A method of modifying a particle that includes reacting a reactive compound having an X-[Y]n reactive group with a secondary compound N-S-ZM to form a substituted reactive intermediate [Y]a-X-(N-S-ZM)b, and reacting the particle with the substituted reactive intermediate [Y]a-X-(N-S-ZM)b to attach the substituted reactive intermediate to the surface of the particle to form a surface modified particle. The particle may comprise at least one of a dye particle, an inorganic pigment particle, an additive, or a combination thereof. X may be a sulfonyl, phosphoryl, or 1,3,5-triazinyl group. Y may be a halogen leaving group. N may be a nucleophilic group. S may be an organic group. ZM may be an ionizable end group. Also, n is an integer between 1 and 3, b is an integer between 1 and 3, and a = n-b. When n is equal to or greater than b, and wherein if b is 2 or 3, each N-S-ZM can be the same or different.
