Abstract: A recording medium comprises a substrate coated with a light reflecting layer which in turn is coated with a light absorbing layer selected from the group consisting of Pt complexes of bis-(dithio-.alpha.-diketones) which have the formula: ##STR1## wherein R is a phenyl or substituted phenyl group. During recording, portions of the absorbing layer are ablated, vaporized or melted by an intensity-modulated, focussed light beam, thereby exposing portions of the reflective layer and recording video information as a reflective-antireflective pattern.

Abstract: Ortho-quinone diazide compounds of the formula ##STR1## wherein R is an organic radical are useful sensitizers for photoresist compositions and intermediates for novel dyes.
