A compound having a novel structure and a photo-sensitive composition comprising (i) the novel compound as a sensitizing dye, (ii) an activator compound generating at least one of a radical and an acid by interacting the activator compound with light absorption of the sensitizing dye to cause chemical change, and (iii) a compound changing its physical or chemical property irreversibly by a reaction with at least one of the radical and the acid.
Where the novel compound has the structure
wherein A represents an aromatic or heterocyclic ring which may have a substituent; X represents an oxygen atom, a sulfur atom or =NR7; R1,R2,R3,R4,R5,R6 and R7 each independently represents a hydrogen atom or a monovalent nonmetallic atom group, provided that at least one of R2,R3,R4,R5 and R6 is a substituent represented by -OR8, in which R8 independently represents a monovalent nonmetallic atom group; and n represents an integer of 1 to 6.
一种具有新结构的化合物和一种光敏组合物,包括(i)新化合物作为感光染料,(ii)激活剂化合物通过与感光染料的光吸收相互作用产生至少一个自由基和酸,引起化学变化,和(iii)通过与至少一个自由基和酸反应而不可逆地改变其物理或化学性质的化合物。其中,新化合物具有结构,其中A代表一个芳香或杂环环,可以具有取代基;X代表氧原子、硫原子或=NR7;R1、R2、R3、R4、R5、R6和R7各自独立地表示氢原子或一价非金属原子基团,但至少其中一个是由-OR8表示的取代基,在其中R8独立地表示一价非金属原子基团;n表示1至6的整数。
