A polymeric diamino triazine dispersing agent comprising a compound the essential parts of which are a diamino triazine group and a polymer chain having a molecular weight of at least 1000, which compound has been obtained by reacting a diamino triazine and a polymer chain having a molecular weight of at least 1000 with an oxiran containing compound. The dispersing agent comprises compounds of the formulas <IMAGE> I <IMAGE> II and <IMAGE> III wherein R1 is aryl or alkyl having 1-8 carbon atoms, R2 is a hydrocarbon radical optionally comprising one or more ether groups and having a molecular weight of less than 200, and R3 is a polymer chain residue having a molecular weight of at least 1000. The dispersing agent can be used for dispersing solid particles, such as pigment particles, in a non polar solvent.
