The present invention relates to a composition comprising
(i) at least one sensitizer compound that, upon exposure to electromagnetic radiation, changes from a ground state into an excited state;
and
(ii) at least one acid generating compound that, upon transfer of energy or an electron from the sensitizer compound in its excited state to the acid generating compound, releases an acid, the acid generating compound having the general structure (I)
wherein
- R1, R2, R3, R4, R5 and R6 independently from each other represent a hydrogen atom or an organic residue, with the provisio that at least one of R1, R2, R3, R4, R5 and R6, preferably at least one of R2 and R3, is an organic residue;
- R7 represents an organic residue.
The present invention also relates to a process for producing a composite, to the composite obtained by the process according to the present invention, to a composite comprising a substrate and a coating applied on the surface of the substrate in a patterned structure and to the use of a combination of a sensitizer compound and an acid generating compound for photoinduced polymerization, photoinduced crosslinking, photoinduced degradation and photoinduced transformation of functional groups.
本发明涉及一种组合物,其中包括
(i) 至少一种敏化剂化合物,该化合物在暴露于电磁辐射时从基态变为激发态;
和
(ii) 至少一种酸生成化合物,当能量或电子从激发态的敏化剂化合物转移到酸生成化合物时,该化合物释放出一种酸,酸生成化合物具有一般结构 (I)
其中
- R1、R2、R3、R4、R5 和 R6 相互独立地代表氢原子或有机残基,但 R1、R2、R3、R4、R5 和 R6 中至少有一个是有机残基,最好是 R2 和 R3 中至少有一个是有机残基;
- R7 代表有机残留物。
本发明还涉及一种生产复合材料的工艺,涉及根据本发明的工艺获得的复合材料,涉及一种复合材料,该复合材料包括基材和以图案结构涂敷在基材表面的涂层,还涉及使用敏化剂化合物和酸生成化合物的组合进行光诱导聚合、光诱导交联、光诱导降解和光诱导官能团转化。
