摘要:
Salts of organic optical brighteners or light stabilizers with compounds which contain at least one ammonium, cycloammonium or immonium group and at least one aliphatic group, cycloaliphatic group, or aromatic group bonded to at least one (up to four) carbonyl group, or heteroaromatic group. resp. basic brighteners or light stabilizers with compounds which contain a radical containing at least one carboxylic acid or sulphonic acid radical and one aliphatic, cycloaliphatic, monomeric aromatic or heteroaromatic group, or contain a C.sub.2-14 -dicarboxylic acid or amino-C.sub.2-1 -alkylcarboxylic acid radical, are eminently suitable for the brightening and light stabilizing of synthetic plastic compositions.
摘要:
A method for preparing a pigment preparation comprising kneading a pigment presscake (comprising a pigment and water and/or one or more organic liquids) at a temperature in the range 80.degree. to 200.degree. C. under vacuum together with a thermoplastic material, thereby at the same time removing the water and/or any organic liquids present. These preparations are useful for coloring polymeric material.
