PURPOSE:To form high-grade multicolor images with decreased overlaps of photosensitive wavelength regions by respectively specifying the polymn. initiators in the components constituting a recording layer. CONSTITUTION:The recording layer on the base of this recording medium consists of the components A-C contg. compds. having unsatd. double bonds and the polymn. initiators. The polymn. initiator in the component A contains the compd. expressed by the formula I and the absorption max. of the polymn. initiator in the component B is in a 360-430nm wavelength region. The absorption max. of the polymn. initiator in the component C is in a >=430nm wavelength region. In the formula, R1 denotes 1-6C alkyl group or phenyl group which may have a substituent; R2 denotes a phenyl group which may have a substituent. The multicolor images which have less overlaps of the photosensitive wavelength regions of the polymn. initiators and are bright even with light of relatively low energy such as fluorescent lamp are obtd. in this way. |
