A1

An object of the invention is to facilitate the reuse of an uncured resin. Another object is to improve the fixability of a masking material to a photocurable material. The invention relates to a method of curing a photocurable resin comprising a first ingredient and a second ingredient. The first ingredient is one which upon mixing with the second ingredient comes to have enhanced photocurability. An example of the first ingredient is a photopolymerizable material of the sol-gel conversion type. An example of the second ingredient is a photopolymerization initiator. The method comprises the following steps. (1) A step in which the second ingredient (12), (22) is supplied to those areas of the first ingredient (11), (21) which are to be cured.
