The instant invention relates to new photolatent compounds of the formula I wherein R
1
and R
2
are each independently of the other C
1
-C
10
alkyl or C
3
-C
8
cycloalkyl, R
3
is hydrogen or C
1
-C
4
alkyl, and wherein the photochemically cleaved group R
4
OH is selected from the group consisting of fragrances, UV absorbers, anti-microbials, anti-fogging agents and clarifiers; with the proviso that, when R
1
and R
2
are tert-butyl and R
3
is hydrogen, R
4
is not methyl or phenyl.
本发明涉及公式I的新型光潜化合物,其中R1和R2各自独立地为C1-C10烷基或C3-C8环烷基,R3为氢或C1-C4烷基,光
化学剪断基团R4OH选自
香料、
紫外线吸收剂、抗微
