PURPOSE: To provide a radiation polymerizable mixture having improved corrosion resistance and dielectric strength.
CONSTITUTION: The radiation polymerizable mixture contains the following components. They are (a) a compound having at least one of free radical polymerizable group, (b) a polymer like binder soluble in an aq. alkaline solution but insoluble in water, (c) a fine particulate mineral pigment consisting essentially of silicic acid or a silicate, which has reactivity itself and a surface improved by the reaction with a compound containing a free radical crosslinkable or thermal cosslinkable group, (d) a polymerization initiator activated by radiation or a combination of polymerization initiators and (e) a compound capable of being crosslinked itself, with the binder (b) or with the compound (a) by heating.
