The present invention has its object to provide a photoradical- and photocation-curable composition improved in curability.
The present invention relates to
a photoradical- and photocation-curable composition which comprises:
(A) a vinyl polymer having, per molecule, two or more groups represented by the general formula (1):
-OC(O)C(Ra)=CH2 (1)
wherein Ra represents a hydrogen atom or an organic group containing 1 to 20 carbon atoms, at least one of which groups occurs at a molecular terminus, and
(B) an epoxy compound and/or oxetane compound and that the N atom-containing compound concentration in the component (A) is not higher than 1,000 ppm and the N atom-containing compound concentration relative to the component (B) is not higher than 2,300 ppm.
本发明的目的是提供一种可提高固化性的光降解和光致发光固化组合物。
本发明涉及
一种光致抗坏和光致脱落固化组合物,它包括
(A)
乙烯基聚合物,每个分子具有两个或两个以上由通式(1)表示的基团:
-OC(O)C(Ra)=
CH2(1)
其中 Ra 代表氢原子或含有 1 至 20 个碳原子的有机基团,其中至少一个基团位于分子末端,以及
(B) 环氧化合物和/或氧杂
环丁烷化合物,且组分 (A) 中含 N 原子化合物的浓度不高于 1,000 ppm,相对于组分 (B) 含 N 原子化合物的浓度不高于 2,300 ppm。
