The present invention relates to a positive working photosensitive composition having an improved sensitivity due to the use of a sensitizer and having an excellent incandescent light safty. This composition comprises at least 1 molar % of a structural unit derived from at least one of monomers having the following general formulae:
wherein:
R₁ represents a hydrogen atom, an alkyl group or a substituted alkyl group,
R₂ represents a divalent alkylene group or a substituted divalent alkylene group,
R₃, R₄ and R₅ may be the same as or different from each other and each represents an alkyl group, a substituted alkyl group, an aryl group or a substituted aryl group,
R₆ and R₇ may be the same as or different from each other and each represents a hydrogen atom, an alkyl group, a substituted alkyl group, an aryl group or a substituted aryl group,
Ar₁ represents a single bond or Ar₂, and
Ar₂ represents a divalent arylene group or a substituted divalent arylene group.
本发明涉及一种正工作光敏组合物,由于使用了增感剂,其灵敏度有所提高,并具有极佳的白炽灯安全性。这种组合物包含至少 1 摩尔%的结构单元,该结构单元至少来自具有以下通式的单体之一:
其中
R₁ 代表氢原子、烷基或取代烷基、
R₂ 代表二价亚烷基或取代的二价亚烷基、
R₃、R₄ 和 R₅ 可以相互相同或不同,各自代表烷基、取代烷基、芳基或取代芳基、
R₆ 和 R₇ 可以相同或互不相同,各自代表氢原子、烷基、取代烷基、芳基或取代芳基、
Ar₁ 代表单键或 Ar₂,以及
Ar₂ 代表二价芳基或取代的二价芳基。
