Abstract

[Problem] To provide an LED-curable composition for photomolding excellent in LED curability and reusability of a mold, and a molded member using the same. [Solution] An LED curable composition for photomolding, comprising the following components (A) and (B). Component (A): photopolymerization initiator having a molar extinction coefficient at 385 nm of 20 L*mol-1*cm-1 or more; and Component (B):an ethylenically-unsaturated group-containing compound; wherein the content ratio of the component (A) is 0.05 parts by mass or more and less than 10 parts by mass with respect to 100 parts by mass of the component (B).

Description

technical field [0001] The invention relates to an LED curable composition for light shaping and its application. Background technique [0002] Photocurable compositions are used in various applications such as coating agents, inks, resists, adhesives, and sealants, and are widely used as curing systems using ultraviolet lamps such as high-pressure mercury lamps and metal halide lamps as light sources. [0003] In recent years, ultraviolet irradiation devices using light-emitting diodes (hereinafter referred to as "LEDs") as light sources have been developed as curing systems modified from these ultraviolet lamps. [0004] LED light sources have the advantages of long light source life and excellent energy-saving properties, but have the disadvantage that the surface curability of the coating film composed of the composition is significantly inferior compared with the conventional ultraviolet light source. This is because a monochromatic light source does not emit light in ...
