본 발명은 이중 칼라 광중합에 의해 출발 물질을 국부적으로 중합하기 위한 공정, 장치 및 광전환성 개시제, 및 성형체의 체적 프린팅을 위한 방법(xolography)에 관한 것이다. 특히, 2개의 상이한 파장으로의 조사 시에 광중합 가능한 포뮬레이션의 경화를 야기시키고 체적 프린팅을 위해 사용될 수 있는 광개시제(xolocure 개시제)가 사용된다. The present invention relates to a process, an apparatus and photoswitchable photoinitators for locally polymerizing a starting material by dual color photopolymerization and a method for volumetric printing of a shaped body (xolography). In particular, photoinitiators are provided, which cause curing of photopolymerizable formulations upon irradiation with two different wavelengths and which may be used for volumetric printing (xolocure initiators).
