Zusammenfassung:	PCT No. PCT/EP95/03431 Sec. 371 Date Feb. 28, 1997 Sec. 102(e) Date Feb. 28, 1997 PCT Filed Sep. 1, 1995 PCT Pub. No. WO96/08007 PCT Pub. Date Mar. 14, 1996The light-induced modification in a side-chain polymer containing at least one side group whose configuration can be modified induced by light and at least one permanently shape-anisotropic side group can be amplified by warming to a temperature between the glass transition temperature and the clearing point. This effect opens up new aspects for optical data storage.
