By using an amine hydrochloride represented by the formula (1) as a catalyst, a polythiourethane resin which is suitably used for a transparent resin for optical use, can be obtained without using an organotin compound which has been conventionally used as a catalyst for polythiourethane resins and without being affected by the acidity of an additive:
wherein R1, R2 and R3 independently represent a monovalent or higher valent linear aliphatic, branched aliphatic, cyclic aliphatic or aromatic organic residue which may have a hydroxyl group or an amino group; and R1, R2 and R3 may be arbitrarily bonded to each other to form a ring.
