The invention relates 6-acyl-(6H)-dibenz[c,e][1,2]oxaphosphorin-6-oxides of the formula ##STR1## wherein each of R.sup.1, R.sup.2 and R.sup.3 may be present one or more times and R.sup.1, R.sup.2 and R.sup.3 represent halogen having an atomic number of from 9 to 35, alkyl or alkoxy each having from 1 to 6 carbon atoms and wherein Ar represents an aromatic hydrocarbon group having from 6 to 10 carbon atoms. The invention further relates to a process for the preparation of the afore-mentioned compounds and polymerizable compositions containing them as an essential ingredient as a photo-initiator. Finally the invention relates to 6-alkoxy-(6H)-dibenz[c,e][1,2]oxaphosphorin of the formula II ##STR2## wherein each of R.sup.1 and R.sup.2 may be present once or more times and R.sup.1 and R.sup.2 represent halogen having an atomic number of from 9 to 35, alkyl or alkoxy each having from 1 to 6 carbon atoms, at least one R.sup.1 being, however, halogen and wherein R.sup.4 represents alkyl having from 1 to 6 carbon atoms.
该发明涉及公式为6-酰基-(6H)-二苯[c,e][1,2]氧代磷杂环己烷-6-氧化物的化合物,其中R.sup.1、R.sup.2和R.sup.3中的每一个可能出现一次或多次,R.sup.1、R.sup.2和R.sup.3代表原子序数为9至35的卤素,具有1至6个碳原子的烷基或烷氧基,其中Ar代表具有6至10个碳原子的芳香烃基。该发明还涉及制备上述化合物的方法以及含有它们作为光引发剂的必要成分的可聚合组合物。最后,该发明涉及公式为II的6-烷氧基-(6H)-二苯[c,e][1,2]氧代磷杂环己烷的化合物,其中R.sup.1和R.sup.2中的每一个可能出现一次或多次,R.sup.1和R.sup.2代表原子序数为9至35的卤素,具有1至6个碳原子的烷基或烷氧基,但至少一个R.sup.1为卤素,其中R.sup.4代表具有1至6个碳原子的烷基。
