摘要:
A photosensitive element for the production of near infrared absorbing images having a photosensitive medium comprising a trialkyl orthoester, a photochemical source of a strong acid and a compound of the formula (I):
in which:
n is 0 or 1,
R¹ and R² independently represent hydrogen or an alkyl group of up to 5 carbon atoms and
Ar₁ and Ar₂ represents aryl groups bearing an electron-donating substituent in the 4-position.
