A method for manufacturing a luminescent horological component for a portable object comprising the following steps:
- mixing an epoxy resin and a phosphorescent pigment in an amount of 40% by mass;
- adding to the mixture a fluorescent pigment in an amount of 3% by mass;
- optionally, adding silane to the mixture in an amount of 10% by mass;
- adding a hardener and mixing everything mechanically to obtain a homogenous solution;
- pouring under vacuum the solution obtained into a mould and cross-linking the solution to obtain a luminescent moulded part;
- after hardening, removing the part from the mould and blanking it by laser to obtain the luminescent horological component.
