Abstract

A method for preparing a color laser marked article using three infrared lasers L- 1 L- 2 and L -3 having respectively a laser emission wavelength of A(L- 1) , A(L -2) and A(L- 3) and comprising the steps of: • - laser marking with the infrared laser L- 1 a first color laser markable layer including an infrared dye IR- 1 having an absorption maximum in the infrared region λ max (IR- 2); • - laser marking with the infrared laser L- 2 a second color laser markable layer including an infrared dye IR -3 having an absorption maximum in the infrared region λmax (IR 2); • laser marking with the infrared laser L- 3 a third color laser markable layer including an infrared dye IR- 3 having an absorption maximum in the infrared region λ (IR- 3); and • at least partially exposing the color laser markable article to light having a wavelength between 520 nm and 700 nm • wherein the laser emission wavelengths satisfy the condition of: λ (L- 1 ) > λ(L -2) > λ(L -3); • the infrared dye absorption maxima satisfy the condition of: λmax(IR- 1 ) > λmax(IR- 2) > λmax(IR -3); and • the light emitted by the infrared laser L- 1 passes , in order - through the third and second color laser markable layer before exposing the first color laser markable layer.
