The object of the present invention is to provide a photocurable resin composition which allows obtainment of a cured product that has high concealability, while being suppressed in fading due to ultraviolet light, a cured product of the photocurable resin composition, and a method for producing a cured product.
The present invention relates to a photocurable resin composition containing the following component (A) to component (D):
component (A): leuco dye;
component (B): photoacid generating agent;
component (C): radical polymerizable compound; and
component (D): α-hydroxy acetophenone-based radical initiator which has a 5% weight loss temperature (thermal decomposition temperature) in a nitrogen atmosphere of 200° C., or higher as determined by a TGA method at a temperature increase rate, of 10° C./minute.
本发明的目的是提供一种光固化树脂组合物,该组合物可获得具有高隐蔽性的固化产品,同时可抑制紫外线引起的褪色;提供该光固化树脂组合物的固化产品;以及提供生产固化产品的方法。
本发明涉及一种光固化树脂组合物,它含有以下组分(A)至组分(D):
组分(A):白炭黑染料;
组分(B):光酸生成剂
成分(C):可自由基聚合的化合物;以及
组分 (D):α-羟基苯乙酮基自由基引发剂,其在氮气环境中的失重 5%温度(热分解温度)为 200 摄氏度,或通过 TGA 方法以 10 摄氏度/分钟的升温速率测定的更高温度。
