The present invention provides a novel triazine derivative of the formula
wherein ring A is an optionally substituted aromatic group which be;
X is an oxygen or sulfur atom;
R1 and R6 are each a hydrogen atom or an optionally substituted hydrocarbon residue or heterocyclic group which may bound through a hetero-atom;
R2 and R3 are each independently a hydrogen atom, a halogen atom, or a group bound through a carbon, oxygen or sulfur atom, or taken together, represent ═S;
R4 and R5 are each independently a hydrogen atom, a halogen atom, or a group bound through a carbon, oxygen, nitrogen or sulfur atom;
R1 and R2, and R5 and R6, may each bind together to form a chemical bond; provided that where ring A is a phenyl group having at least a halogen atom in position-2 or 4 and X is an oxygen atom, R4 and R5 do not conjoinedly represent a chemical bond and an antiprotozoan composition containing the same or salt thereof.

The present invention provides a novel triazine derivative of the formula ##STR1## wherein ring A is an optionally substituted aromatic group; X is an oxygen or sulfur atom; R.sup.1 and R.sup.6 are each a hydrogen atom or an optionally substituted hydrocarbon residue or heterocyclic group which may bound through a hetero-atom; R.sup.2 and R.sup.3 are each independently a hydrogen atom, a halogen atom, or a group bound through a carbon, oxygen or sulfur atom, or taken together, represent .dbd.S; R.sup.4 and R.sup.5 are each independently a hydrogen atom, a halogen-atom, or a group bound through a carbon, oxygen, nitrogen or sulfur atom; R.sup.1 and R.sup.2, and R.sup.5 and R.sup.6 may each bind together to form a chemical bond; provided that where ring A is a phenyl group having at least a halogen atom in position -2 or 4 and X is an oxygen atom, R.sup.4 and R.sup.5 do not conjoin to form a chemical bond, or a salt thereof. The invention also encompasses an antiprotozoan composition comprising the novel triazine derivative or a salt thereof.
