PV Fast Maroon HFM based polyurethane ionomers were successfully synthesized at our lab, and these ionomer structures have been proven by infrared spectra. In aqueous solution, the surface tension was found to be lower for the HFM pigment‐based polyurethane ionomer made by toluene diisocyanate (TDI), as a result of more hydrophobicity adsorbed at the surface of aqueous solution. The viscosity decreases with increasing the concentration of the HFM pigment used to prepare the HFM pigment based polyurethane ionomer, indicating that the structure of this ionomer is possibly considered to be a type of micelle. In addition, the number‐average particle sizes are seen to be decreased with increasing the concentration of HFM pigment employed for making the HFM pigment based polyurethane ionomer. These results also suggest that the HFM pigment based polyurethane ionomer molecule could have a micelle‐like sturcture. However, the 100% modulus property for both the IPDI type or the TDI type of PV Fast maroon HFM based PU ionomer molecules appears to increase gradually with increasing the concentration of HFM, as a result of more crosslinking formed. ©1996 John Wiley & Sons, Inc.
