Process for obtaining aminotriazine derivatives, of the general formula: ** (see formula) ** Wherein a means an alkyl radical, optionally branched, or an alkenyl radical with a maximum of 6 carbon atoms and b means an alkyl radical, optionally branched, with a maximum of 6 carbon atoms, and i defines as a hydrogen atom, an amino group, an alkyl group with a maximum of 4 carbon atoms, a phenyl group or a group (see formula) having a and b the meaning defined above; characterized in that aminotriazine derivatives of the general formula: ** (see formula) ** Wherein y means hydrogen, an alkyl group with a maximum of 4 carbon atoms, a phenyl group or an amino group and r represents hydrogen or a group (see formula), in which a and b have the meaning defined above, where in the case that y has a meaning different from the amino group, at least one of the r means hydrogen, they react at least with 1/2 excess mol, in relation to the equivalent amount of the number of groups (see formula) to introduce, of an aldehyde of the general formula: ** (see formula) ** Where b has the definition indicated above and at least 1 mol in excess, in relation to the equivalent amount of the number of groups (see formula) to be introduced, of a primary or secondary alcohol, saturated or unsaturated, of general formula: A - oh (IV) Wherein a has the above defined definition, at a temperature comprised between 50º and at most the boiling temperature of the reaction mixture, and in the presence of an inorganic or organic acid as catalyst, after which the existing ether groups are re-etherifying by heating with another primary or secondary alcohol, preferably longer chain, of formula a-oh, wherein a has the meaning defined above, in the presence of an inorganic or organic acid as a catalyst.
