A latex formed from a cold pressure fix toner composition comprising:

• a crystalline organic material comprising:
• (1) a crystalline polyester;
• or
• (2) a crystalline ester;
• wherein the crystalline organic material has a melting point in a range from about 30° C. to about 130° C.;
• and
• an amorphous organic material comprising:
• (a) a rosin ester;
• (b) styrenated terpenes, polyterpenes, or terpene phenolics;
• or
• (c) a hydrogenated hydrocarbon resin derive from a 5 carbon aliphatic monomer or 9 carbon aromatic monomer;
• wherein the amorphous organic material having a Tg of from about −30° C. to about 70° C., and the number average molecular weight Mn of the amorphous organic material is from about 300 to about 1200, and the weight average molecular weight Mw is from about 300 to about 2,000.
