| 摘要 |
The invention concerns the use, as a buffer dispersing agent for compositions and bases for water-based paints and pigmentary compositions in aqueous phase similar to paints, of the combination of a partially or totally neutralised water-soluble dispersing agent which is a homopolymer of acrylic or methacrylic acid with at least one other unsaturated ethylenic monomer, alone or in mixture, with a compound having specific buffer properties. It also concerns buffer dispersing agents and the compositions and bases for water-based paints and pigmentary compositions in aqueous phase similar to the paints containing them. |
