Abstract
A silicone composition having superior moisture- and photocurability and easy to manufacture is provided. A polyorganosiloxane having primary amino, (meth)acryl or epoxy groups at both ends is reacted with a compound having two to three hydrolyzable groups and also having (meth)acryl or epoxy group in the case where the said end groups are primary amino groups, or also having a primary amino group in the case where the said end groups are (meth)acryl or epoxy groups, then the resulting reaction product is reacted with a compound having vinyl group and (meth)acryl, epoxy or isocyanato group, to prepare a polysiloxane having hydrolyzable groups and vinyl group, and this polysiloxane is combined with a photopolymerization catalyst and a moisture-curing catalyst.
