摘要:
A process for making a latex emulsion suitable for use in a toner composition includes contacting at least one polyester resin with a bio-based solvent to form a resin mixture, adding a neutralizing agent and deionized water to the resin mixture, removing the solvent from the formed latex, and recovering the emulsion. The solvent removed from the formed latex may be re-used, making the process very environmentally friendly.
摘要:
Disclosed is a polyester resin comprising the polycondensation product of (a) at least one diacid, acid ester, or diester; and (b) at least one diol; wherein either (i) at least one diacid, acid ester, or diester comprises a rosin diacid, rosin acid ester, or rosin diester; or (ii) at least one diol comprises a rosin diol, and wherein at least one of the rosin diacid, rosin acid ester, rosin diester, or rosin diol is either (A) an ester of a functionalized rosin or an ester of a reduced functionalized rosin, or (B) a dimerized rosin. Also disclosed is a toner composition comprising particles which comprise the disclosed polyester resin and an optional colorant.
摘要:
Substituted oxazoline compounds and/or substituted oxazoline derivatives having amorphous, semi-crystalline, or crystalline properties and methods for producing such compounds and derivatives are presented. The substituted oxazoline compounds and/or substituted oxazoline derivatives are useful for various applications. For example, the substituted oxazoline compounds and/or substituted oxazoline derivatives may function as phase-change agents, a binder resins, rheology modifiers or plasticizers for ink compositions.
摘要:
A solid ink composition comprising at least one crystalline oxazoline compound and at least one amorphous component derived from a polyol, and a colorant and optional viscosity modifier, which are suitable for inkjet printing, including printing on coated paper substrates. In embodiments, the solid ink formulation comprises a blend of an amorphous and crystalline components which provides a solid ink with excellent robustness when forming images or printing on coated paper substrates.
