| 摘要 |
The invention relates to an aqueous polymeric dispersion where :
- it comprises :
a) at least one polymer in aqueous dispersion, having a minimum film forming temperature (MFFT) between 0 and 100°C, and
b) 0.05 to 30% by weight with respect to the said aqueous dispersion a), of at least one organic carboxylic acid in C 1 to C 25 , or their mixtures,
- the said organic carboxylic acid b) and its content in the said aqueous dispersion is selected to be compatible with the said aqueous polymeric dispersion as such and with the said polymer as polymer itself,
- the said acid b) is in its acid form. The invention does also cover a process of preparation, an end-use composition comprising the said aqueous polymeric dispersion for various specific uses in : paints, varnishes, inks, glues, adhesives, fibre sizing compositions or textile or leather treatment compositions, or food coatings or packagings. |
