Non-ionic surface active compounds and photographic materials containing them.

摘要

Water soluble surface active compounds are provided having the formula wherein each of R<1> and R<2> independently is hydrogen, substituted or unsubstituted alkyl, substituted or unsubstituted cycloalkyl, or substituted or unsubstituted aryl, provided that not both R<1> and R<2> are hydrogen, and each of x and y independently is an integer from 3 to 6. The compounds are particularly useful as coating aids and dispersing aids in the preparation of photographic materials.
