<P>PROBLEM TO BE SOLVED: To provide a photosensitive composition and a curing method capable of curing up to a deep part irrespective of the presence or absence of materials suppressing ultraviolet (UV) ray penetration such as organic and inorganic fillers, carbon and metal particles, short and long fibers, polymers and oligomers and various modification additives. <P>SOLUTION: The UV-ray curable composition is brought to be chain-cured, irrespective of the presence or absence of the materials suppressing the UV-ray penetration in the UV-ray curable composition by using the photosensitive composition containing a chain transfer agent capable of chain-curing the UV-ray curable material in the presence of the UV-ray curable material and the UV-ray penetration-suppressing material for suppressing the UV-ray penetration, and bringing curing active moieties generated by irradiating with the UV-rays the UV-ray curable composition to propagate up to a part where the UV-rays can not reach by means of the chain transfer agent. <P>COPYRIGHT: (C)2013,JPO&INPIT |
