Non-ionic surface active compounds |
| abstract |
Water-soluble, non-ionic surface active compounds are provided having the formula <IMAGE> wherein R1 and R2 are each independently hydrogen or an alkyl group having from 1 to 4 carbon atoms; X is a hydrophobic substituted or unsubstituted arylene group or a hydrophobic substituted or unsubstituted alkylene group; Y1 and Y2 are each independently a chemical bond, -CO- or -(CH2)mNR3CO-; m is an integer from 1 to 6; R3 is as defined for R1 and R2; and, Z1 and Z2 are each independently a hydrophilic polyhydroxyalkyl group. The compounds are particularly useful as coating aids for the coating of hydrophilic colloid layers in the preparation of photographic materials. |
