We present the observation of coherent population trapping resonances on the second resonance line of potassium: 4s^{2}S_{1/2} → 5 p^{2}P_{3/2} with wavelength of 404.4 nm. Moreover, a transfer of the coherent population trapping resonance occurs to the excited 4p^{2}P_{1/2} and 4p^{2}P_{3/2} states of the first resonance line due to cascade transitions. This transfer is evidenced by the observation of narrow resonances at the infrared 4s^{2}S_{1/2} → 4p^{2}P_{1/2} and 4s^{2}S_{1/2} → 4 p^{2}P_{3/2} transitions when alkali excitation is performed at the 404.4 nm violet line.
