Abstract
The present invention relates to a composition based on isocyanate(s), advantageously not completely masked. This composition is defined in that it comprises a compound containing an anionic functional group and a polyethylene glycol chain fragment of at least 5, advantageously of at least 7 ethyleneoxy units. Application to organic synthesis.

A coating composition, consisting essentially of, in emulsion in water, a composition autodispersible in aqueous phase which is a mixture of an aliphatic isocyanate composition, with at least one surfactant containing an anionic functional group, a countercation and, a polyethylene glycol chain fragment having one or more ethyleneoxy units, wherein the anionic functional group of said surfactant corresponds to the following formula:
- wherein:
- q is zero or 1;
- pis 1 or 2;
- m is 0 or 1;
- the sum:
- 1+p+2m+q is equal to three or to five;
- X and X′ are a divalent group;
- s is an integer chosen between 1 and 30;
- n is an integer chosen between 1 and 30;
- E is a phosphorus atom;
- and
- R1 and R2 are a hydrocarbon radical.
