A photopolymerizable or radiation polymerizable alkaline developing crosslinking curable resin composition possessing superior antiplating properties and a short stripping period, in which the stripped plate is not easily dissolved in the stripping fluid, and which is comprising:
(a) 5-30 parts by weight of at least one compound possessing in one molecule on the average 1.5 or more (meth)acryloyloxy groups, which is obtained by reacting (meth)acrylic acid with a reaction product formed by adding, to a polyatomic alcohol possessing 3 or more OH groups in one molecule, an alkylene oxide containing propylene oxide in an amount of 67% molar or greater in an amount of 5-12 moles per mole of OH group in the aforementioned polyatomic alcohol,
(b) 5-30 parts by weight of at least one crosslinkable monomer other than that stated above in (a), possessing in one molecule 2 or more ethylenically unsaturated groups,
(c) 45-75 parts by weight of a thermoplastic polymer for use as a binder, the thermoplastic polymer in turn being formed of 15-35 wt % of at least one α,β-unsaturated carboxyl group containing a monomer having 3-15 carbon atoms, and 65-85 wt % of another copolymerizable monomer, and
(d) 0-10 parts by weight of a photopolymerization initiator.
一种可光聚合或可辐射聚合的碱性显影交联固化树脂组合物,具有优异的防电镀性能和较短的剥离周期,剥离后的板材不易溶解在剥离液中,它包括
(a) 5-30 份(按重量计)至少一种化合物,其分子中平均含有 1.5 个或更多的(甲 基)丙烯酰氧基,该化合物是通过将(甲基)丙烯酸与一种反应产物反应而得,该 反应产物是通过向一种分子中含有 3 个或更多羟基的多原子醇中加入一种含氧 化丙烯的环氧烷,其摩尔量为 67%或更高,在上述多原子醇中每摩尔羟基的 含量为 5-12 摩尔、
(b) 5-30 份(重量)除上述(a)所述单体外的至少一种可交联单体,其一个分子中 具有 2 个或 2 个以上乙烯不饱和基团、
(c) 45-75 重量份用作粘合剂的热塑性聚合物,该热塑性聚合物又是由 15-35 重量份含有 3-15 个碳原子的单体的至少一个α,β-不饱和羧基和 65-85 重量份另一种可共聚的单体组成,以及
(d) 0-10 重量份的光聚合引发剂。
