  公开（公告）日：2004-12-02

  Cationic initiator compositions for initiating cationic polymerization which contain a sulfur- or nitrogen-containing initiator, such as a sulfonium salt photoinitiator, and a deodorizing agent are disclosed. The deodorizing agent reduces undesirable odors, such as the organosulfur/mercaptan/thio odor generated by the decomposition of the sulfonium salt initiator upon initiation. The deodorizing agent may be a free radical inhibitor or phenolic compound such as methylether of hydroquinone, toluhydroquinone and hydroquinone. Processes for making and using the composition are also disclosed. The composition has applications in the coating, photoresist, adhesion, graphic arts and sealant arts among others

  本发明公开了用于引发阳离子聚合的阳离子引发剂组合物，该组合物含有含硫或含氮引发剂（如锍盐光引发剂）和除臭剂。除臭剂可减少不良气味，例如锍盐引发剂在引发时分解产生的有机硫/硫醇/硫代气味。除臭剂可以是自由基抑制剂或酚类化合物，如氢醌的甲基醚、对苯二酚和对苯二酚。此外，还公开了该组合物的制造和使用方法。该组合物可应用于涂料、光刻胶、粘合剂、图形艺术和密封剂等领域。
• 2,5-Dihydroxybenzyl and (1,4-Dihydroxy-2-naphthyl)methyl, Novel Reductively Armed Photocages for the Hydroxyl Moiety
  作者：Alexey P. Kostikov、Vladimir V. Popik

  DOI：10.1021/jo701426j

  日期：2007.11.1

  [Graphics]Irradiation of alcohols, phenols, and carboxylic acids "caged" with the 2,5-dihydroxybenzyl group or its naphthalene analogue results in the efficient release of the substrate. The initial byproduct of the photoreaction, 4-hydroxyquinone-2-methide, undergoes rapid tautomerization into methyl p-quinone. The UV spectrum of the latter is different from that of the caging chromophore, thus permitting selective irradiation of the starting material in the presence of photochemical products. These photoremovable protecting groups can be armed in situ by the reduction of photochemically inert p-quinone precursors.
